食源性疾病
40 道题The Temperature Danger Zone is 41°F to 135°F; bacteria multiply fastest between these limits, and growth is most rapid from 70°F to 125°F. Cold holding must stay at or below 41°F and hot holding at or above 135°F to keep food out of the zone. The other ranges are incorrect because they do not match the Food Code limits.
Cold TCS (Time/Temperature Control for Safety) food must be held at 41°F or below. At 45°F or 50°F the food is inside the danger zone and pathogens can grow. 38°F is safe but is not the maximum allowed limit the question asks for.
FDA Food Code §3-501.16Hot TCS food must be held at 135°F or above. 125°F is inside the danger zone and unsafe. 145°F and 155°F are cooking temperatures for certain foods, not the minimum hot-holding requirement.
FDA Food Code §3-501.16TCS food reheated for hot holding must reach 165°F for 15 seconds within 2 hours. Reaching only 135°F, 145°F, or 155°F would not destroy pathogens that may have grown, and taking longer than 2 hours keeps food in the danger zone too long.
FDA Food Code §3-403.11Poultry must be cooked to 165°F for 15 seconds because it commonly carries Salmonella and Campylobacter. 155°F is for ground meat, 145°F is for whole cuts and seafood, and 175°F is not a Food Code standard.
FDA Food Code §3-401.11Ground meat such as hamburger must reach 155°F for 17 seconds because grinding spreads surface bacteria throughout the patty. Whole cuts only need 145°F since bacteria stay on the surface, and 165°F is for poultry.
FDA Food Code §3-401.11Whole muscle seafood, steaks, chops, and shell eggs cooked for immediate service require 145°F for 15 seconds. 155°F applies to ground meat, and 165°F to poultry; 135°F is a holding temperature, not a cooking temperature.
FDA Food Code §3-401.11FAT TOM stands for Food, Acidity, Temperature, Time, Oxygen, and Moisture, the six factors that control bacterial growth. Controlling temperature and time is the tool managers rely on most. The other options substitute incorrect words like Fat or Minerals.
Cut melons, including cantaloupe, are TCS foods because cutting exposes the moist, low-acid flesh where bacteria can grow. Whole citrus, uncooked dry rice, and shelf-stable honey are not TCS in their listed state. Once rice is cooked it becomes TCS.
Hepatitis A is a virus linked to raw or undercooked shellfish and to infected food handlers with poor handwashing, and it can cause jaundice. Salmonella, Shigella, and STEC are bacteria, not viruses. Hepatitis A is one of the Big 6 highly infectious pathogens.
Norovirus is extremely contagious and spread by the fecal-oral route, so excluding sick employees and strict handwashing plus no bare-hand contact with ready-to-eat food are the key controls. Freezing does not kill Norovirus, sanitizer alone is not effective against it, and 135°F is a holding temperature, not a kill step.
Nontyphoidal Salmonella is commonly found in poultry, eggs, meat, and fresh produce, and cross-contamination spreads it. Cooking to required temperatures and avoiding cross-contamination are the main controls. Highly acidic or dry, shelf-stable items are not typical vehicles.
Salmonella Typhi lives only in humans and is spread when an infected food handler contaminates food, often via ready-to-eat items and beverages. It is one of the Big 6. Refrigeration does not destroy it, and it clearly affects humans, causing typhoid fever.
Shigella is spread by the fecal-oral route, often through flies, contaminated water, and food handlers who do not wash hands after using the restroom. It commonly contaminates ready-to-eat foods and salads. Controlling handwashing and excluding ill staff are key, not freezing.
STEC is strongly linked to undercooked ground beef and to contaminated produce, and even a small dose can cause severe illness such as hemolytic uremic syndrome. Cooking ground beef to 155°F controls it. Canned tomatoes, boiled rice, and pasteurized milk are not typical STEC vehicles.
Highly susceptible populations include young children, older adults, pregnant women, and people with weakened immune systems, because their bodies fight infection less effectively. Facilities serving these groups (such as hospitals and nursing homes) must not serve certain raw or undercooked foods. Healthy adults and athletes are not high-risk by definition.
Scombroid poisoning is caused by histamine that forms when fish like tuna, mahi-mahi, and mackerel are time-temperature abused; symptoms appear rapidly and include flushing and rash. The histamine is not destroyed by cooking, so cold storage is critical. Ciguatera comes from reef fish toxins and botulism causes neurological paralysis.
Ciguatera toxin accumulates in large predatory reef fish such as barracuda, amberjack, and large grouper; the toxin cannot be destroyed by cooking or freezing. Buying fish from approved, reputable suppliers is the main control. Farmed tilapia, cod, and canned sardines are not typical ciguatera sources.
Anisakis is a roundworm parasite found in raw or undercooked fish; freezing fish at required temperatures for the required time destroys it, which is why fish for raw service must be frozen unless exempt. Salmonella is bacteria, Norovirus a virus, and Clostridium botulinum a toxin-forming bacterium.
Some molds produce dangerous mycotoxins, so moldy soft foods, breads, and high-moisture items should be thrown out; only certain hard cheeses can have mold trimmed at least an inch away. Not all mold is harmless, mold does not require the freezer to grow, and most yeasts spoil food rather than cause infection.
The complete handwashing process should take at least 20 seconds, including vigorous scrubbing with soap for 10 to 15 seconds. Five or ten seconds is too short to remove pathogens, and while thorough washing is important, the Code sets a minimum of 20 seconds total.
FDA Food Code §2-301.14The two-stage cooling method requires cooling from 135°F to 70°F within 2 hours, then from 70°F to 41°F within an additional 4 hours, for a total of 6 hours. If the food does not reach 70°F within the first 2 hours it must be reheated or discarded. The 2-hour first stage limits the time bacteria spend in the fastest-growth range.
FDA Food Code §3-501.14After the first stage brings food to 70°F within 2 hours, the second stage must bring it from 70°F down to 41°F within 4 more hours, for a maximum total of 6 hours. Allowing more time would keep the food in the danger zone too long and permit pathogen growth.
FDA Food Code §3-501.14Clostridium botulinum grows and forms toxin in anaerobic, low-acid, moist environments such as improperly home-canned foods, ROP (reduced-oxygen packaged) foods, and garlic-in-oil mixtures. Oxygen and high acidity inhibit it, and it does not thrive in dry foods. The toxin attacks the nervous system.
Bacillus cereus forms heat-resistant spores that survive cooking; if cooked rice or pasta is left in the danger zone, the bacteria grow and produce toxins that reheating may not destroy. This is why cooked rice must be cooled quickly or held at safe temperatures. It is not limited to raw meat and can survive in cooked food.
Listeria monocytogenes can grow at cold refrigeration temperatures and is dangerous to pregnant women, causing miscarriage, as well as to elderly and immunocompromised people. It is often found in deli meats, soft cheeses, and smoked seafood. Refrigeration slows most bacteria but not Listeria, so date-marking and discarding old ready-to-eat foods matter.
Ready-to-eat TCS food held at 41°F or below may be kept for a maximum of 7 days, with the day of preparation counted as day 1. After 7 days the food must be discarded because Listeria and other pathogens can slowly grow even under refrigeration. Shorter counts are not required by the Code, and the 5-day framing here misstates the counting rule.
FDA Food Code §3-501.17Under time as a public health control, cold TCS food may be held up to 6 hours if it begins at 41°F or below and does not exceed 70°F, after which it must be discarded. Alternatively, food may be held up to 4 hours with no temperature limit. The item must be labeled with the discard time; 12 or 24 hours is far too long.
FDA Food Code §3-501.19An employee diagnosed with Norovirus (one of the Big 6) must be excluded from the food establishment and can only return when cleared according to the Food Code, typically after being symptom-free for at least 24 to 48 hours and with regulatory approval. Gloves, reassignment, or simply avoiding food contact are not sufficient for a Big 6 diagnosis.
FDA Food Code §2-201.12Food handlers must report to the manager and be restricted or excluded when they have vomiting, diarrhea, jaundice, a sore throat with fever, or an infected open wound, as these signal pathogens that can contaminate food. Headache, tiredness, dry skin, or a properly bandaged minor cut do not by themselves require exclusion.
FDA Food Code §2-201.11Shellfish toxins such as those causing paralytic shellfish poisoning are naturally occurring, heat-stable, and not destroyed by cooking or freezing, so the only control is buying shellfish from approved, reputable suppliers with proper tags. Cooking to 145°F will not neutralize the toxin, and PSP causes neurological symptoms, not just a rash.
Whole-muscle roasts may be cooked to 145°F held for 4 minutes, or to an approved lower temperature held for a longer time, because the interior of an intact roast has few surface bacteria. Poultry needs 165°F and ground meat 155°F, while 135°F is only a holding temperature, not a safe cook temperature for roasts.
FDA Food Code §3-401.11In an intoxication, the person eats a toxin already produced in the food (for example by Staphylococcus aureus, often introduced by bare-hand contact), so symptoms appear quickly, sometimes within hours. An infection requires living pathogens to multiply in the body, with a slower onset. Good hygiene, especially handwashing and no bare-hand contact, helps prevent Staph intoxication.
Staphylococcus aureus lives in the nose, mouth, skin, and infected cuts of many healthy people and is transferred to ready-to-eat food by bare-hand contact; the toxin it forms is heat-stable and not destroyed by cooking. Controls include handwashing, no bare-hand contact with ready-to-eat food, and keeping food out of the danger zone. Freezing, acidity, or undercooking vegetables are not the transfer routes.
Highly susceptible guests such as immunocompromised patients should not be served raw or undercooked animal foods like raw oysters, because their weakened immune systems cannot fight pathogens such as Vibrio or Norovirus. Fully cooked chicken, pasteurized juice, and properly hot-held soup are safe choices.
Shell eggs that are pooled or will be hot-held (not cooked to order for immediate service) must reach 155°F for 17 seconds, the same as ground meat, because pooling and holding increase risk. Eggs cooked to order for immediate service only need 145°F. 135°F is a holding temperature, not a cooking temperature.
FDA Food Code §3-401.11Raw animal foods cooked in a microwave must reach 165°F, and the food should be rotated or stirred, covered, and allowed to stand for 2 minutes after cooking to even out cold spots. Microwaves heat unevenly, so the higher 165°F standard and the standing time add a safety margin. Lower temperatures like 145°F or 155°F apply to conventional cooking of certain foods, not microwaving raw animal foods.
FDA Food Code §3-401.11STEC and Shigella are notable for very low infectious doses, so even slight contamination of ready-to-eat food can cause serious illness, which is why handwashing and no bare-hand contact are critical. Clostridium perfringens and Bacillus cereus generally require larger numbers to cause illness, and Staph illness depends on toxin buildup from time-temperature abuse.
Cyclospora and Giardia are parasites, often spread through contaminated water or fresh produce irrigated or washed with contaminated water. Buying from approved suppliers and using safe water are key controls. Bacteria, viruses, and fungi are separate categories of biological hazards.
When an outbreak is suspected, the manager should gather information from affected guests, isolate and label the suspect food so it is not thrown out or served, and contact the local health department. Discarding the evidence, ignoring reports, or hiding information would hinder the investigation and endanger more customers.
污染与过敏原
40 道题The three categories of food contamination are biological (pathogens like bacteria and viruses), chemical (cleaners, sanitizers, toxic metals), and physical (foreign objects like glass or metal). Recognizing all three helps managers build controls for each. Bacterial/viral/fungal are all subtypes of biological hazards.
Storing chemicals above or next to food risks chemical contamination if the cleaner leaks or splashes onto the food. Chemicals must be stored in a separate area, below and away from food and food-contact surfaces. This is not biological or physical contamination, and degreaser is not a food allergen.
A foreign object such as glass, metal shavings, bandages, or bone is physical contamination. Managers prevent it with practices like not using glassware to scoop ice and inspecting produce. It is not chemical, biological, or an allergen issue.
Cross-contamination is the transfer of pathogens from one food or surface to another, such as raw poultry juices dripping onto ready-to-eat produce or using the same unwashed cutting board. Storing raw meats below ready-to-eat foods and using separate equipment prevent it. Natural spoilage, seasoning, and proper cooking are not cross-contamination.
Foods should be stored top to bottom in order of increasing required cooking temperature: ready-to-eat foods on top, then whole seafood/steaks (145°F), then ground meat (155°F), with raw poultry (165°F) on the bottom. This prevents juices from higher-temperature raw items from dripping onto foods cooked less or eaten raw. Covering alone does not remove the risk of drips and spills.
FDA Food Code §3-302.11Sesame became the ninth major allergen in the U.S. under the FASTER Act, joining milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, and soybeans. Corn, garlic, and mustard are not among the U.S. Big 9. Managers must be able to identify all nine on their menus.
When a guest asks about allergens, staff must give accurate information, so an unsure server should check with the kitchen or manager and verify every ingredient before answering. Guessing, reassuring without facts, or removing visible allergens does not eliminate hidden allergen proteins or cross-contact and can trigger a life-threatening reaction.
Cross-contact occurs when an allergen protein is unintentionally transferred to a food that should be allergen-free, for example frying shrimp and then french fries in the same oil, or using the same unwashed utensils. Unlike pathogens, allergen proteins are not destroyed by cooking, so cooking hotter does not help. Freezing and intentional safe mixing are unrelated.
Because allergen proteins are not destroyed by heat, the kitchen must prevent contact entirely by using clean, sanitized equipment and surfaces, washing hands, and often preparing the dish in a separate area. Cooking hotter, rinsing, or serving less does not remove the allergen and can still cause a severe reaction.
Allergic reactions can include hives, itching, swelling of the face or throat, wheezing, and difficulty breathing, which can progress to life-threatening anaphylaxis within minutes. Staff should call for emergency help immediately. A mild delayed stomachache, improved energy, or food cravings are not the warning signs of a serious allergic reaction.
ALERT stands for Assure (use safe suppliers), Look (monitor security of products and areas), Employees (know who is in the facility), Reports (keep records of security), and Threat (know what to do and who to contact if there is a threat). It is a food defense tool against intentional contamination. The other options are invented phrases.
Deliberate contamination is intentional, done by people seeking to cause harm through tampering, sabotage, or terrorism, and food defense programs like ALERT help prevent it. Accidental contamination comes from mistakes in handling. Security measures such as limiting access and monitoring suppliers do help reduce the risk.
The manager should take the complaint seriously, stop serving the affected batch of soup, retrieve the object, and investigate where it came from, such as loose equipment parts, to prevent recurrence. Ignoring it, dismissing the hazard, or blaming others without investigation fails to protect guests and correct the root cause.
Chemicals must be stored physically separated from food, equipment, utensils, and single-service items, typically in a dedicated area below or away from them, and in clearly labeled original or working containers. Storing them with food, in prep sinks, or in unlabeled containers risks chemical contamination and mistaken use.
FDA Food Code §7-201.11Physical contaminants are hard or soft foreign objects like metal staples, glass, bones, hair, or bandages that can injure a guest. Salmonella is biological, cleaning residue is chemical, and peanut protein is an allergen. Inspecting deliveries and keeping foreign objects out of food prevent physical contamination.
To prevent cross-contamination, food-contact surfaces used for raw meat must be washed, rinsed, and sanitized before use with ready-to-eat food, or separate color-coded boards and utensils should be used. Wiping with a dry towel or rinsing in warm water does not remove or kill pathogens. Cutting produce first then meat helps only if the surface is still cleaned between raw meats and later uses.
An allergen-free claim requires controlling hidden allergen ingredients (like peanut oil or flour) and cross-contact from shared fryers, utensils, prep surfaces, and gloves, not just visible pieces. Even trace amounts from shared equipment can cause a reaction. Price and plate color are irrelevant to allergen safety.
Soy sauce typically contains both wheat and soybeans, two of the Big 9 allergens, which can surprise guests who do not realize it. Managers and staff must know hidden allergen sources in sauces, marinades, and dressings. Plain rice, a whole apple, and water do not contain Big 9 allergens.
Food that shows signs of pests, damage, or contamination should be rejected at the receiving dock and not accepted into the establishment, protecting the food supply. Washing, separating, or freezing contaminated product does not make it safe. Rejecting problem deliveries is a key manager control point.
Preventing cross-contact requires washing hands, putting on clean gloves, and using freshly cleaned and sanitized equipment, utensils, and surfaces dedicated to that order. Keeping the same gloves, working amid other allergen-containing foods, or sharing a fryer with breaded shrimp would transfer allergen proteins to the meal.
Almonds are tree nuts, along with walnuts, cashews, pecans, and pistachios. Peanuts are legumes and are their own separate Big 9 allergen, while chickpeas and sunflower seeds are not among the Big 9. Because peanuts and tree nuts are separate categories, both must be tracked individually.
An infected wound can carry Staphylococcus aureus, so it must be covered with a clean impermeable bandage and, on the hand, a single-use glove or finger cot; if the infection is significant, the handler may need to be restricted from working with food. Simply being careful, rinsing, or ignoring the wound risks contaminating food with pathogens.
Storing or serving food in a container that held a toxic chemical, or letting cleaner residue reach food, is chemical contamination. A hair is physical, raw beef juice on lettuce is biological cross-contamination, and a milk allergy is an allergen concern. Using only food-grade containers and controlling chemicals prevents this hazard.
Anaphylaxis is a life-threatening emergency, so staff must call emergency services immediately, follow the operation's emergency plan, and assist the guest, who may need epinephrine. Waiting, offering water, or leaving the guest alone can cost precious minutes and be fatal. Managers should train staff to recognize and respond to reactions.
Handling ready-to-eat food with gloves, tongs, or other utensils instead of bare hands reduces biological contamination from pathogens like Norovirus, Hepatitis A, Shigella, and Staph carried on hands. While good practices also help with allergens, the bare-hand rule primarily targets pathogen transfer. It is not aimed at glass or sanitizer.
A core food-defense practice is limiting access to preparation and storage areas so only authorized employees enter, reducing opportunities for deliberate tampering. Propping doors open, allowing unknown visitors into the kitchen, or storing chemicals with food all increase vulnerability to intentional and accidental contamination.
Regular flour tortillas are made from wheat flour and must be avoided for a wheat-allergic guest, while corn tortillas, plain grilled chicken, and white rice are wheat-free. Managers should teach staff which menu items and substitutions are safe. Reading labels and recipes helps catch hidden wheat in breading, sauces, and thickeners too.
Preventing physical contamination involves removing potential foreign objects: not wearing jewelry that can fall in, using shatter-resistant light shields, keeping fingernails trimmed, and inspecting food for bones, pits, or packaging. Cooking temperature, salt, and room-temperature storage address other hazards, not physical objects.
Unlike most pathogens, allergen proteins are not destroyed by cooking or freezing, so the only reliable protection for an allergic guest is preventing the allergen from contacting the food at all. This is why cooking hotter, freezing, or rinsing cannot make a dish safe once cross-contact has occurred.
A strong ammonia smell, dull sunken eyes, and slimy or soft flesh indicate spoilage, so the fish should be rejected. Fresh fish has bright red gills, firm flesh that springs back, clear eyes, and only a mild sea smell. Accepting spoiled fish risks scombroid poisoning and other illness.
Milk allergens hide in ingredients such as butter, whey, casein, and many creamy sauces, so staff must read labels and recipes carefully. Olive oil, vinegar, and plain black coffee do not contain milk. Knowing hidden dairy sources is essential to protect a milk-allergic guest.
Cold TCS food should be received at 41°F or below; deliveries arriving warmer than 41°F should be rejected because time-temperature abuse may have allowed pathogen growth. Accepting food at 50°F, 60°F, or 70°F would bring unsafe product into the operation. Checking delivery temperatures is a key receiving control.
A clear communication system, such as marked tickets, allergen flags, or verbal confirmation between servers and kitchen, ensures everyone knows an order must be allergen-safe. Serving last, hiding information, or leaving it to individual judgment increases the chance of a mistake that could harm an allergic guest.
Soy is a hidden allergen in many sauces, dressings, marinades, and processed foods, so staff must read labels. Eggs also hide in mayonnaise, baked goods, and batters, fish (as anchovies) appears in sauces like Worcestershire and Caesar dressing, and peanuts appear in oils, sauces, and desserts, so the other statements are false.
A metal fragment from a scouring pad in food is a physical contaminant that could injure a guest. Managers should keep such tools away from open food and inspect for stray fragments. It is not an allergen, chemical, or biological hazard.
Crustacean shellfish includes shrimp, crab, lobster, and crawfish, all of which must be avoided and kept from cross-contact for this guest. Beef, broccoli, and rice are not crustacean shellfish. Note that mollusks like clams and oysters are a separate category, though many operations treat all shellfish carefully.
During events like a boil-water advisory, sewage backup, or contamination emergency, the manager must protect guests by stopping the affected operations, discarding unsafe food, and following the local regulatory authority's guidance, which may require closing until it is safe. Continuing to serve to protect sales endangers guests and violates food safety responsibilities.
For a recall, the manager should identify and remove the recalled product from service, label it clearly as 'Do Not Use' or 'Do Not Sell,' store it separately from other food, and follow the recall notice instructions for return or disposal while keeping records. Continuing to sell, hiding it, or discarding it without documentation fails to protect customers and comply with the recall.
Raw chicken should be thawed in the cooler on the bottom shelf, in a pan or container that catches drips, and kept below and away from ready-to-eat foods so juices cannot contaminate them. Thawing above produce, uncovered next to cooked food, or on the counter overnight all invite cross-contamination or time-temperature abuse.
The first step is to take the allergy seriously, listen to the guest, and identify exactly which allergens must be avoided so the kitchen can prepare a safe meal or advise against certain dishes. Dismissing the guest, recommending dishes blindly, or falsely claiming everything is allergen-free can lead to a dangerous reaction.
个人卫生
40 道题Food handlers may not touch ready-to-eat food with their bare hands; they must use suitable utensils such as single-use gloves, tongs, spatulas, or deli tissue. Even clean, recently washed hands can transfer pathogens like Norovirus and Staphylococcus aureus. Sanitizer does not replace this barrier, and the rule applies whether the food is hot or cold.
FDA Food Code §3-301.11The complete handwashing procedure must take at least 20 seconds, which includes vigorously scrubbing hands and arms with soap for 10 to 15 seconds. Five or three seconds is far too short to remove soil and pathogens, and while 60 seconds is thorough, the Code sets 20 seconds as the minimum standard, not a fixed 60.
FDA Food Code §2-301.12Hands must be washed after handling raw meat, poultry, or fish and before switching to ready-to-eat foods, to prevent cross-contamination with pathogens like Salmonella. A quick water rinse or a spray of sanitizer does not remove the load of pathogens the way soap, warm water, and 20 seconds of scrubbing do. Changing aprons alone does not address contaminated hands.
FDA Food Code §2-301.14A handwashing sink must be used only for washing hands; it may not be used to rinse equipment, prep food, or dump mop water, because doing so can contaminate the sink and discourage proper handwashing. The problem is not the sink size or water temperature. Equipment must be cleaned in a designated warewashing or prep sink instead.
FDA Food Code §5-205.11Hands may be washed only at a sink designated for handwashing, not in sinks used to prepare food, wash dishes, or dump mop water, because those sinks can cross-contaminate hands or food. A handwashing sink must be stocked with warm running water, soap, and a way to dry hands. Convenience is never a reason to wash hands in a prep or utility sink.
FDA Food Code §2-301.15Single-use gloves must be discarded and hands washed whenever they become contaminated, such as after taking out trash, and a fresh pair put on before handling food. Gloves are single-use only; they cannot be wiped, sanitized, or reused. The hands must be washed between glove changes because the gloves themselves do not replace handwashing.
FDA Food Code §3-304.15Gloves must be changed when they are torn or soiled, when switching tasks or foods, after handling raw meat before touching ready-to-eat food, and at least every four hours of continuous use. Waiting until the end of a shift lets contamination build up. A strict four-hour rule alone ignores tears and task changes, and glove changes should not depend on a manager's reminder.
FDA Food Code §3-304.15An employee diagnosed with Norovirus, one of the Big 6 pathogens, must be excluded from the establishment and can return only when cleared per the Code, generally after being symptom-free at least 24 to 48 hours with regulatory approval. Gloves, reassignment to the counter, or ignoring it because she 'only' washes dishes all leave a highly contagious pathogen in the operation.
FDA Food Code §2-201.12An employee with vomiting or diarrhea must be excluded from the operation because these symptoms strongly signal a transmissible foodborne pathogen. A restriction (keeping the person away from food and clean equipment) applies to lesser situations, but active vomiting or diarrhea calls for full exclusion. A cough, headache, or tired eyes alone do not by themselves require exclusion.
FDA Food Code §2-201.11A food handler with jaundice that appeared within the last seven days must be excluded, and the regulatory authority must be notified, because jaundice can indicate Hepatitis A, one of the Big 6. This is especially critical where a highly susceptible population such as a nursing home is served. Restriction, gloves, or a brief break are not sufficient responses to jaundice.
FDA Food Code §2-201.11A food handler with a sore throat accompanied by fever must be restricted from working with food and food-contact surfaces (but need not be fully excluded) when serving the general population; exclusion is required only when a highly susceptible population is served. Ignoring the symptom or continuing to serve tables normally risks transmitting Streptococcus. A 30-day exclusion is not the Code standard.
FDA Food Code §2-201.11An infected wound or lesion containing pus on the hand must be covered with an impermeable (waterproof) bandage and then a single-use glove or finger cot, because Staphylococcus aureus in the wound can contaminate food. Leaving it uncovered or using a paper towel provides no barrier, and extra handwashing alone does not contain an infected lesion.
FDA Food Code §3-301.11Employees may drink in food prep areas only from a container that is covered with a lid and straw, held so that hands and the food are not contaminated, and away from exposed food and clean equipment. Open cups are prohibited because they can spill and expose the drinker's saliva to the hands. The rule is not limited to water, and reasonable drinking areas are allowed, so a total building ban is incorrect.
FDA Food Code §2-401.11Smoking, vaping, and chewing gum or tobacco are prohibited in food prep and service areas because they encourage hand-to-mouth contact and can contaminate food and surfaces. Employees who eat, smoke, or chew must do so only in designated areas and wash hands afterward. Wearing a clean apron, washing hands, and wearing a hair restraint are all required good practices, not violations.
FDA Food Code §2-401.11Food handlers must keep fingernails trimmed, filed, and clean so they can be maintained; if they wear nail polish or artificial nails, they must wear gloves when touching exposed food, because polish can chip into food and artificial nails can harbor pathogens and break off. Long nails and chipped polish trap soil and pathogens. Clean, short natural nails are the safe standard for bare-hand tasks like handwashing.
FDA Food Code §2-302.11While preparing food, a food handler may wear a plain band ring (such as a wedding band) with no stones, but must remove watches, bracelets, and other rings, because jewelry can harbor pathogens, fall into food, or catch on equipment. Rings with stones and bracelets create crevices that are hard to clean. A plain smooth band is the only commonly allowed item.
FDA Food Code §2-303.11Hair restraints such as caps, hairnets, and beard covers keep hair out of food and discourage handlers from touching their hair, which can transfer oils and pathogens to the hands. The purpose is food safety, not just appearance or comfort. Loose hair is a physical contaminant and a route for Staphylococcus that lives on skin and hair.
FDA Food Code §2-402.11Soiled clothing and aprons must be changed when they become contaminated, such as with raw egg, because they can transfer pathogens to food and hands; the handler should also wash hands. Wiping the apron or turning it around does not remove the contamination, and waiting until it is fully soiled allows cross-contamination in the meantime. Aprons should be removed before using the restroom or taking out trash as well.
FDA Food Code §2-304.11Handwashing is required after using the restroom, touching the body or hair, handling raw animal foods, coughing or sneezing, taking out trash, and before starting food work, among others. Simply tying on a clean apron over hands that are already clean and freshly washed does not, by itself, contaminate the hands. All the other options involve clear contamination that demands washing.
FDA Food Code §2-301.14Hand antiseptics may be used only after hands are properly washed and dried; they supplement but never replace handwashing, because sanitizer does not remove soil and is less effective on soiled hands or against some pathogens like Norovirus. Using sanitizer instead of washing, especially after the restroom, is a serious violation. Hands that merely look clean can still carry pathogens.
FDA Food Code §2-301.16Handling money contaminates the hands, so a cashier must wash her hands, and use deli tissue, a utensil, or gloves, before handling ready-to-eat pan dulce, because bare-hand contact with ready-to-eat food is prohibited. Although the bread was baked earlier, it will not be cooked again, so contamination now reaches the customer. Wiping hands on an apron and washing only once per shift are both inadequate.
FDA Food Code §2-301.14Coughing or sneezing, even into a tissue, contaminates the hands, so the cook must wash his hands before returning to food. Using a tissue helps, but discarding it still transfers respiratory secretions and pathogens to the hands. A mask or a short wait does not remove contamination the way handwashing does.
FDA Food Code §2-301.14An employee excluded for vomiting or diarrhea may generally return when symptom-free for at least 24 hours, or with approval from the regulatory authority or a medical practitioner, depending on the pathogen. Returning while still symptomatic or after only two hours risks spreading pathogens such as Norovirus. A blanket 30-day exclusion is not the standard for simple vomiting/diarrhea without a specific diagnosis.
FDA Food Code §2-201.13The Person in Charge must ensure that food employees know to report required symptoms (vomiting, diarrhea, jaundice, sore throat with fever, infected wounds) and Big 6 diagnoses, and must apply the correct exclusion or restriction. The manager does not diagnose illness or prescribe medicine, and being short-staffed is never a valid reason to keep a sick handler working.
FDA Food Code §2-103.11The best compliance is to use single-use gloves (or utensils like tongs) and change gloves between tasks, when torn or soiled, and at least every four hours, keeping bare hands off the ready-to-eat greens. Washing once then using bare hands violates the no-bare-hand rule. Keeping the same gloves through task changes or rinsing bare hands in a prep sink both allow contamination.
FDA Food Code §3-301.11Proper handwashing is: wet hands and arms with warm running water, apply soap, vigorously scrub hands, arms, between fingers, and under nails for 10 to 15 seconds, rinse thoroughly, and dry with a single-use paper towel or hand dryer, for a total of at least 20 seconds. The other sequences put steps out of order or use an apron, which recontaminates the hands.
FDA Food Code §2-301.12He should have washed hands after handling raw pork (before touching anything else), and again after touching his cell phone, which is a contaminated non-food surface, before portioning the ready-to-eat carnitas. That is at least two missed handwashing points. Cell phones are not clean, and gloves worn earlier do not excuse washing between these contamination events.
FDA Food Code §2-301.14The Food Code calls for a sign or poster at handwashing sinks used by food employees, reminding them to wash their hands before returning to work. This reinforces the handwashing culture that prevents fecal-oral pathogen transmission. A no-smoking sign, a menu, or a morale poster do not satisfy this specific requirement.
FDA Food Code §6-301.14Employees may eat, drink (from open containers), and take breaks only in designated areas away from exposed food, equipment, utensils, and prep surfaces, and must wash hands before returning to work. Eating at a prep table or over open food risks contaminating it with saliva, crumbs, and hand-to-mouth pathogens. Speed does not justify eating in food areas.
FDA Food Code §2-401.11Hands must be washed before putting on single-use gloves, because gloves placed over dirty hands can be contaminated during use and through small tears. Gloves are a supplement to, not a replacement for, handwashing. Rinsing gloves in sanitizer or rubbing hands on a towel does not clean the hands underneath.
FDA Food Code §2-301.14Taking out trash contaminates the hands, so the cook must wash his hands before handling food again, even if he thinks he did not touch the garbage directly, because bins, lids, and door handles are contaminated. Changing gloves without washing the hands underneath, or merely wiping the hands, does not remove the pathogens. Handwashing is required after this task.
FDA Food Code §2-301.14Bare-hand contact is prohibited with ready-to-eat food, but it is acceptable to handle food with bare hands when that food will still be cooked to its required temperature afterward, because cooking is a kill step. Plating cold sandwiches, garnishing desserts, and adding fresh herbs all involve ready-to-eat food and require gloves or utensils. Washing produce destined for cooking does not trigger the ready-to-eat rule.
FDA Food Code §3-301.11Employees with facial hair who prepare exposed food should wear an effective beard restraint, along with a hair restraint for head hair, to keep hair out of food. Facial hair can and does shed into food, so doing nothing is incorrect. A hat alone does not cover a beard, and shaving is not required, a beard cover is the practical control.
FDA Food Code §2-402.11Handwashing frequency depends on activity, not the pace of business: hands must be washed before starting food work and whenever they become contaminated, such as after the restroom, handling raw animal foods, touching the face or hair, taking out trash, or switching tasks. Washing only once, only when visibly dirty, or on a rigid 30-minute timer misses the actual contamination events that matter.
FDA Food Code §2-301.14A diagnosed Big 6 illness such as STEC (along with Salmonella Typhi, nontyphoidal Salmonella, Shigella, Hepatitis A, and Norovirus) requires excluding the food handler and reporting the diagnosis to the regulatory authority. Restriction, gloves, or waiting for symptoms are inadequate because the handler can shed the pathogen. Reinstatement follows the Code and regulatory clearance.
FDA Food Code §2-201.11During food preparation, employees must remove bracelets, watches, and fitness trackers from hands and arms, keeping only a plain band ring, because such jewelry harbors pathogens, can fall into food, and interferes with handwashing and glove use. Taping over jewelry or gloving over bracelets does not solve the contamination and cleaning problems; the items must simply be removed.
FDA Food Code §2-303.11The fecal-oral route is how many of the most dangerous foodborne pathogens spread, including Norovirus, Shigella, Hepatitis A, and STEC, so washing hands after the restroom is critical to breaking that route. It is a food-safety control, not a matter of smell, dress code, or customer perception. This is why handwashing sinks and signage are required near restrooms.
FDA Food Code §2-301.14When serving a highly susceptible population, a food handler diagnosed with nontyphoidal Salmonella must be excluded even if asymptomatic, because these guests are especially vulnerable. In a general operation, an asymptomatic nontyphoidal Salmonella diagnosis may be restricted rather than excluded, but the high-risk setting raises the standard. Letting the handler work or ignoring the diagnosis is unsafe.
FDA Food Code §2-201.11Frequent, correct handwashing at the right moments is the single most effective personal-hygiene control against foodborne illness, since hands are the main vehicle for transferring pathogens to food. Cologne and gum do nothing for safety, and gum-chewing is prohibited in prep areas. Long, painted nails without gloves actually harbor pathogens and violate the Code.
After handling raw ground beef, the cook must wash his hands thoroughly, and put on clean gloves, before plating the cooked, ready-to-eat quesadillas, to avoid transferring pathogens like STEC and Salmonella. Simply swapping gloves without washing leaves contaminated hands underneath, and a cold-water rinse does not sanitize. The quesadillas will not be cooked again, so contamination now reaches the guest.
FDA Food Code §2-301.14收货与储存
40 道题Food must be obtained from approved, reputable suppliers that comply with applicable federal, state, and local laws and are inspected as required, because food safety begins with a safe source. Price, delivery time, and distance are business conveniences, not safety controls. Buying from unapproved sources, such as an unlicensed roadside seller, is prohibited.
FDA Food Code §3-201.11Cold TCS food such as raw chicken must be received at 41°F or below, so it enters the operation out of the danger zone. Receiving at 45°F, 50°F, or 60°F means the food has been time-temperature abused and should be rejected. The 45°F allowance applies only to specific items like live shellfish, shell eggs, and milk, not to raw chicken.
FDA Food Code §3-202.11Hot TCS food must be received at 135°F or above to stay out of the temperature danger zone. Receiving at 125°F, 130°F, or 110°F means the food has cooled into the danger zone where pathogens can grow, and it should be rejected. The receiving standard mirrors the hot-holding minimum of 135°F.
FDA Food Code §3-202.11Frozen food should be received frozen solid; signs of thawing and refreezing, such as large ice crystals, pooled frozen liquid, or water stains on the case, indicate time-temperature abuse and require rejection. Being cold, solidly frozen, or properly labeled with a harvest date are all good signs, not reasons to reject. Refreezing lets pathogens grow during the thaw period.
FDA Food Code §3-202.11Live molluscan shellfish may be received at an internal temperature of 45°F or below, a specific allowance recognizing how they are shipped; they must then be cooled appropriately. Requiring 41°F or 32°F is stricter than the Code demands for receiving live shellfish, while 50°F is too warm and would be a basis for rejection. Shellstock must also arrive with proper identification tags.
FDA Food Code §3-202.11Shellstock identification tags must be kept, in order and marked with the date the last shellfish was used, for 90 days from that date, so illnesses can be traced to the harvest source. Keeping them only 24 hours or 7 days is too short for traceback, and a full year is more than the Code requires. The tag links each container to its harvest location and date.
FDA Food Code §3-203.12Shell eggs must be received and stored in refrigerated equipment that maintains an ambient air temperature of 45°F or below, which helps limit Salmonella growth inside the egg. 55°F and 50°F are too warm, and while 41°F is also acceptable, the specific Code allowance for shell eggs is an ambient 45°F, so stating 41°F as the only limit is incorrect. Eggs should be used promptly after receiving.
FDA Food Code §3-202.11Fluid milk may be received at 45°F or below, but it must then be cooled to 41°F or below within 4 hours, so a 45°F delivery is acceptable if promptly cooled. It cannot be held at 45°F indefinitely, and it need not be rejected or discarded outright simply for arriving at 45°F. This mirrors the special receiving allowance the Code gives certain items.
FDA Food Code §3-202.11Cans that are swollen, leaking, rusted, or dented on a seam must be rejected, because these defects can allow contamination or indicate Clostridium botulinum growth. A swollen can is a serious warning sign of gas from toxin-forming bacteria. Intact labels do not make a damaged can safe, and a swollen can must never be used or opened for tasting.
FDA Food Code §3-202.15Deliveries must be rejected when packaging is torn, punctured, or water-stained, when there is evidence of pests such as droppings or gnaw marks, or when there are off odors, slime, or mold, because these indicate contamination or abuse. Neatly stacked cases, properly cold produce, and sealed undamaged bags are all acceptable. The receiving inspection is a key control before food enters storage.
FDA Food Code §3-202.15Once a commercial container of ready-to-eat TCS food is opened, it must be date-marked and used within 7 days when held at 41°F or below, counting the day of opening or preparation as day 1. Fourteen days is too long, and same-day use is stricter than required. Date marking controls slow-growing pathogens like Listeria under refrigeration.
FDA Food Code §3-501.17When ready-to-eat TCS ingredients with different date marks are combined, the finished dish must carry the earliest discard date among its components, so nothing is held past its safe limit. Using the later date, restarting the 7-day count, or dropping the date entirely would let some ingredients exceed the maximum safe age. The 7-day maximum at 41°F still governs each component.
FDA Food Code §3-501.17FIFO means First In, First Out: the oldest product (with the soonest use-by or expiration date) is used first, so newer deliveries are stored behind or beneath existing stock. Using the newest first leaves old product to spoil or expire. FIFO reduces waste and prevents serving out-of-date food; it is a rotation rule, not a color- or inventory-quantity rule.
Ready-to-eat foods and washed produce go on the top shelf, above all raw animal foods, so their juices cannot drip onto and contaminate them. Raw animal foods are stored below in order of their minimum cooking temperature. Placing raw ground beef, chicken, or pork on top would risk dripping pathogens onto ready-to-eat items.
FDA Food Code §3-302.11Raw poultry, which has the highest minimum cooking temperature (165°F), is stored on the bottom shelf so its drippings cannot contaminate foods that are cooked to lower temperatures or eaten raw. Ready-to-eat salads go on top, followed by whole fish and whole cuts of beef, with ground meat below those and poultry at the very bottom. The order follows required cook temperatures.
FDA Food Code §3-302.11The correct top-to-bottom order by minimum internal cooking temperature is: whole salmon (145°F), whole pork chops (145°F), raw ground beef (155°F), then raw chicken (165°F) on the bottom. Foods needing higher cook temperatures go lower so their juices cannot drip onto foods cooked to lower temperatures. The other orders place higher-temperature items above lower-temperature ones, risking contamination.
FDA Food Code §3-302.11Food must be stored at least 6 inches (about 15 cm) off the floor, which protects it from contamination, splash, and pests and allows cleaning underneath. One inch is not enough clearance, storing directly on the floor is prohibited even in boxes, and 24 inches is more than required. Shelving must also be smooth, cleanable, and away from walls where practical.
FDA Food Code §3-305.11Dry storage should be kept between 50°F and 70°F, with good ventilation and low humidity, to keep dry and canned goods safe and slow spoilage and pest activity. A refrigeration range of 32°F to 41°F is for TCS foods, not dry storage; 70°F to 90°F is too warm and speeds spoilage and pests; and below freezing is unnecessary and can damage some products.
To verify receiving temperatures, the clerk should insert a clean, sanitized, calibrated thermometer into the thickest part of the food, or fold the probe between two packages for packaged items, and record the reading. Air temperature, the invoice figure, or touching the box do not give the food's true internal temperature. The probe must be cleaned and sanitized before and after to avoid cross-contamination.
FDA Food Code §3-202.11Storing raw poultry above ready-to-eat food is dangerous because a leak, spill, or condensation drip can carry Salmonella and Campylobacter down onto food that will not be cooked again. That is why raw poultry belongs on the bottom shelf regardless of packaging. The concern is contamination, not odor, airflow, or mere labeling; proper storage order is a physical barrier against cross-contamination.
FDA Food Code §3-302.11Raw ground beef at 50°F must be rejected because cold TCS food must be received at 41°F or below, and 50°F is well inside the temperature danger zone, indicating time-temperature abuse in transit. Accepting it and cooling later, judging by color, or planning to use it quickly all ignore that pathogens may already have grown. Document the rejection and notify the supplier.
FDA Food Code §3-202.11Rejected food should be separated from accepted deliveries so it is not mistakenly used, the reason explained to the driver, and a signed credit slip or adjustment obtained before the truck leaves. Throwing it out yourself forfeits the credit and record; storing rejected food in the walk-in risks accidental use; and accepting then labeling 'do not use' still brings unsafe food into the operation.
Ready-to-eat TCS food held at 41°F or below may be kept a maximum of 7 days, counting the preparation day as day 1, so chicken salad made Monday must be discarded by the end of the following Sunday (day 7). Day 8 exceeds the limit, day 3 is stricter than required, and 'never' is wrong because Listeria can grow slowly even under refrigeration.
FDA Food Code §3-501.17Fresh cut melon is cold TCS food that must be received at 41°F or below, so cut cantaloupe at 50°F must be rejected. Live oysters at 45°F, shell eggs in 45°F ambient air, and milk at 45°F (if cooled to 41°F within 4 hours) all fall within specific Code allowances for those items. The 45°F allowances do not extend to cut produce.
FDA Food Code §3-202.11For temperature safety, the receiver should probe the thickest part of the pork with a clean, calibrated thermometer and confirm it is 41°F or below before accepting. Box weight, price matching, and delivery time are business or quality checks, not temperature verification. If the pork is above 41°F, it has been temperature-abused and should be rejected.
FDA Food Code §3-202.11Labeling each item with a received or use-by date and shelving newer stock behind or below older stock makes FIFO easy, so the oldest, soonest-to-expire product is always used first. Pushing new stock to the front, leaving items unlabeled, or mixing old and new randomly all defeat rotation and increase spoilage and the risk of using expired food.
A reduced-oxygen (ROP/vacuum) package that is puffy, loose, or leaking must be rejected, because loss of the seal can allow oxygen and temperature abuse leading to Clostridium botulinum growth, whose toxin is deadly and not destroyed by cooking. Accepting or freezing a compromised package does not fix the safety risk, and opening it to smell exposes staff and does not make it safe.
FDA Food Code §3-202.15Food must be stored where it is protected from contamination: away from walls, off the floor, and never beneath exposed sewer lines, leaking pipes, condensation, or open stairwells. Storing food under waste lines or leaking pipes invites contamination even if wrapped, and chemicals must be stored below and away from food, never above it, to prevent leaks or spills onto food.
FDA Food Code §3-305.11Frozen food must be received frozen solid; chicken that is partially thawed and pliable shows time-temperature abuse and must be rejected. Refreezing does not undo the microbial growth that occurred while thawed, being merely cold is not sufficient for a product that should be frozen, and accepting it to cook immediately still rewards an unsafe delivery. Document and return it to the supplier.
FDA Food Code §3-202.11Shellstock identification tags must be retained in chronological order, each marked with the date the last shellfish from that container was served or sold, and kept for 90 days to support traceback during an illness investigation. Discarding tags when the container opens, merging them, or keeping them only after a complaint all break the traceability the Code requires.
FDA Food Code §3-203.12Whole fish and whole beef/pork cuts have a minimum cooking temperature of 145°F, lower than ground meat (155°F) and poultry (165°F), so they are stored above ground beef and poultry. Placing them below ground beef or poultry reverses the safe order, and the order always matters among raw meats because juices from higher-temperature items must never drip onto lower-temperature ones.
FDA Food Code §3-302.11All food, including canned goods and shellfish, must come from approved, reputable, regulated sources; home-canned salsa (risking botulism) and untagged shellfish from an unlicensed harvester are prohibited. Taste is not a safety test, and both items fail the approved-source requirement. Shellfish specifically must arrive from a certified dealer with shellstock identification tags.
FDA Food Code §3-201.11Date marking is required for ready-to-eat TCS food prepared on-site or held after opening a commercial container for more than 24 hours; a commercially processed, hermetically sealed container that remains unopened does not require date marking until it is opened. House-made tuna salad, an opened deli container, and cooked-and-cooled pasta are all prepared or opened items that must be date-marked and used within 7 days.
FDA Food Code §3-501.17Fresh fish should have firm flesh, clear bright eyes, red moist gills, and a mild sea smell; soft flesh, cloudy sunken eyes, and a strong ammonia or sour odor are signs of spoilage and the delivery must be rejected. Cooking does not reverse spoilage or remove toxins like histamine, and selling or storing questionable fish only passes the risk to customers.
FDA Food Code §3-202.11Dry goods should be stored on cleanable shelving at least 6 inches off the floor, away from walls, in a clean, dry, well-ventilated room kept between 50°F and 70°F. Stacking on the floor against a wall blocks cleaning and invites pests, 80°F accelerates spoilage and infestation, and storing near a leaking pipe risks contamination even if boxes are covered.
FDA Food Code §3-305.11Ready-to-eat cooked rice must be stored above raw chicken so that chicken juices, which can carry Salmonella, cannot drip down onto food that will not be cooked again. Storing them side by side still risks splash and cross-contamination, and placing chicken above the rice is exactly the wrong order. Proper vertical order is a barrier against cross-contamination.
FDA Food Code §3-302.11The Food Code grants specific 45°F receiving allowances for live molluscan shellfish, shell eggs (ambient air), and milk, reflecting safe shipping practices, but with follow-up controls such as cooling milk to 41°F within 4 hours. These are still TCS foods, 45°F is not the general cold rule (which is 41°F), and temperature very much matters, these are narrow, item-specific exceptions.
FDA Food Code §3-202.11Scheduling deliveries during slow periods lets trained staff inspect temperatures and condition right away and quickly move TCS food into refrigeration or freezing before it enters the danger zone. It does not set prices, it does not eliminate the need for signatures or paperwork, and it certainly does not remove the requirement to check temperatures, prompt inspection is the whole point.
TCS and other foods should be covered and arranged so they are protected from contamination, including overhead drips, condensation, splash, and cross-contamination from raw foods above. Leaving containers open or uncovered under a fan exposes food to airborne and drip contamination, and stacking so raw juices drip between containers is a direct cross-contamination hazard. Covering also helps maintain temperature and quality.
FDA Food Code §3-304.11With the preparation day counted as day 1 and a 7-day maximum at 41°F or below, beans made on July 1 must be discarded by the end of July 7. June 30 is before preparation, July 15 exceeds the 7-day limit, and same-day discard is far stricter than the Code requires. Correct date marking ensures the food is used or discarded within its safe window.
FDA Food Code §3-501.17备制与烹饪
40 道题The FDA Food Code allows exactly four thawing methods: refrigeration at 41°F or lower, submerged under running drinkable water at 70°F or lower, in a microwave when cooking continues immediately, and as part of the cooking process. Room-temperature counters and standing warm water are never approved because the outer layers of the food would sit in the temperature danger zone.
FDA Food Code §3-501.13Running water used for thawing must be drinkable and at 70°F or lower. Warmer water would raise the surface of the food into the temperature danger zone while the center is still thawing, allowing pathogens to grow.
FDA Food Code §3-501.13Thawing under refrigeration at 41°F or lower keeps the food out of the temperature danger zone for the entire process and requires no monitoring, making it the safest method when time allows. Microwave thawing is only allowed when cooking continues immediately, and standing water or ambient thawing is never permitted.
FDA Food Code §3-501.13Cooking food from its frozen state is one of the four approved thawing methods. The key control is that the food must still reach its required minimum internal cooking temperature, in this case 165°F for 15 seconds for poultry.
FDA Food Code §3-501.13Microwave thawing partially heats the food and can bring portions of it into the temperature danger zone. For that reason, food thawed in a microwave must move directly into the cooking process without any holding or storage in between.
FDA Food Code §3-501.13When food thaws at room temperature, its surface can spend hours between 41°F and 135°F even though the core is still frozen. That surface time in the danger zone allows bacteria to multiply, which is why ambient thawing is not one of the four approved methods.
FDA Food Code §3-501.13Working in small batches means only the food being actively prepped is out of refrigeration, while the rest stays at 41°F or lower. This minimizes the total time each portion spends in the danger zone between 41°F and 135°F.
Correct small-batch prep keeps most of the product at 41°F or lower while only a workable amount is on the table. Each finished batch goes back to refrigeration immediately, so no portion accumulates significant time in the temperature danger zone.
Poultry must reach a minimum internal temperature of 165°F held for at least 15 seconds. At 158°F the thigh has not met the requirement, so cooking must continue and the temperature must be rechecked in the thickest part.
FDA Food Code §3-401.11Stuffed foods and stuffing, including stuffed pasta, must be cooked to 165°F for 15 seconds. The dense interior heats slowly and can shelter pathogens, so the highest cooking standard applies regardless of whether the filling contains meat.
FDA Food Code §3-401.11Grinding distributes surface bacteria throughout the meat, so ground beef requires 155°F for 17 seconds rather than the 145°F standard used for whole-muscle steaks. Only patties served under a consumer advisory as undercooked may go below this.
FDA Food Code §3-401.11Mechanically tenderized and injected meats are treated like ground meats and must reach 155°F for 17 seconds. The blades or needles used in tenderizing can push surface pathogens deep into the muscle, so the whole-muscle steak standard of 145°F no longer applies.
FDA Food Code §3-401.11Whole-muscle cuts such as steaks and chops of pork, beef, veal, and lamb must reach 145°F for 15 seconds. Bacteria on intact muscle remain on the surface, which cooks first, so a lower internal temperature is sufficient compared with ground products.
FDA Food Code §3-401.11Seafood, including fish, shellfish, and crustaceans, must be cooked to 145°F for 15 seconds. This is the same standard applied to whole-muscle steaks and chops and to eggs cooked for immediate service.
FDA Food Code §3-401.11Shell eggs cooked to order and served immediately must reach 145°F for 15 seconds. If eggs are pooled or will be held for later service, the higher standard of 155°F for 17 seconds applies instead.
FDA Food Code §3-401.11Whole roasts of beef, pork, and cured products such as ham must reach 145°F and hold that temperature for 4 minutes. The extended hold time compensates for the lower temperature and achieves the required pathogen reduction throughout the large cut.
FDA Food Code §3-401.11Fruits and vegetables that will be hot-held must be cooked to at least 135°F, which matches the minimum hot-holding temperature. No specific hold time is required for plant foods at this temperature.
FDA Food Code §3-401.13Raw animal foods cooked in a microwave must reach 165°F in all parts, be covered, and be rotated or stirred partway through to offset uneven heating. The food must then stand covered for 2 minutes so the temperature can equalize before serving.
FDA Food Code §3-401.12Microwave energy creates hot and cold spots in food. Rotating or stirring during cooking and a 2-minute covered stand afterward allow conduction to even out the temperature so all parts reach 165°F. The temperature should still be verified with a thermometer after the stand time.
FDA Food Code §3-401.12Stuffed foods, including stuffed shrimp, must be cooked to 165°F for 15 seconds, the highest standard on this list. The steak and halibut require 145°F for 15 seconds, and the ground lamb requires 155°F for 17 seconds.
FDA Food Code §3-401.11The first cooling stage requires food to drop from 135°F to 70°F within 2 hours. This stage is the most critical because bacteria grow fastest in the upper part of the danger zone, so the clock for the chili runs from 3:00 to 5:00 p.m.
FDA Food Code §3-501.14Once food reaches 70°F within the first 2 hours, it must continue cooling from 70°F to 41°F within 4 more hours. The entire process from 135°F to 41°F may take no more than 6 hours total.
FDA Food Code §3-501.14The sauce failed the first cooling stage because it did not reach 70°F within 2 hours. The manager-approved corrective actions are to reheat the food to 165°F and re-cool it using a more effective method, or to throw it out. Simply continuing the clock would leave the food too long in the danger zone.
FDA Food Code §3-501.14An ice-water bath works by surrounding the pot with ice and water up to the food level and stirring often so heat transfers out of the entire batch. Adding ice directly to the soup is a separate approved method, but it dilutes the product and only works when the recipe allows water as an ingredient.
FDA Food Code §3-501.15Dividing food into shallow layers, generally 2 inches deep or less for thick products, dramatically increases surface area relative to volume. This speeds heat loss so the beans can pass from 135°F to 70°F within 2 hours and reach 41°F within 6 hours total.
FDA Food Code §3-501.15An ice paddle is a food-safe plastic wand filled with water and frozen solid. Stirring it through hot food pulls heat from the center of the batch, and it is often combined with an ice bath and shallow pans to meet the 2-hour and 6-hour cooling limits.
FDA Food Code §3-501.15Deep containers insulate the center of the food, and a tight cover traps heat and steam, so the rice would stay in the danger zone far past the 2-hour and 6-hour limits. Cooling food should be portioned shallow and left loosely covered or uncovered, protected from contamination, until it reaches 41°F.
FDA Food Code §3-501.15Using ice as an ingredient is an approved cooling method. The soup is cooked concentrated, and the water in the recipe is added at the end as ice, which absorbs heat as it melts and drops the batch temperature quickly without diluting the recipe beyond its intended formula.
FDA Food Code §3-501.15Cutting large dense items into smaller portions is an approved way to speed cooling because heat escapes through the newly exposed surfaces. A whole wrapped brisket would hold heat in its core well beyond the 2-hour first-stage limit.
FDA Food Code §3-501.15The rice dropped from 135°F to 68°F in 2 hours, satisfying the first stage, and reached 40°F at 5.5 hours total, inside the 6-hour overall limit. Shallow panning in a walk-in is an approved combination of methods. Cooked rice is a TCS food, so these limits absolutely apply.
FDA Food Code §3-501.14Food that was cooked, cooled, and will be hot-held must be reheated to 165°F, and the reheating must be completed within 2 hours. Reheating quickly through the danger zone destroys any pathogens that may have grown during cooling and storage.
FDA Food Code §3-403.11Commercially processed, ready-to-eat food such as canned cheese sauce that is being heated for hot holding for the first time must reach at least 135°F. The 165°F standard applies to food that was cooked and cooled in the operation itself.
FDA Food Code §3-403.11Steam tables and other hot-holding units are designed to maintain temperature, not raise it quickly. Reheating in them leaves food in the danger zone too long. Leftover gravy must be reheated to 165°F within 2 hours on a stove, oven, or other cooking equipment before being transferred to hot holding.
FDA Food Code §3-403.11The Food Code allows properly cooked and cooled food that is reheated for immediate service in response to an individual order to be served at any temperature. The 165°F within 2 hours rule applies when reheated food will go into hot holding.
FDA Food Code §3-403.11A consumer advisory has two required parts: a disclosure, which identifies the animal-derived items served raw or undercooked, often with an asterisk on the menu, and a reminder, which states that eating raw or undercooked meats, poultry, seafood, shellfish, or eggs may increase the risk of foodborne illness.
FDA Food Code §3-603.11An operation may serve undercooked ground beef to an adult guest who orders it, provided the menu includes a proper consumer advisory with both the disclosure and the reminder. Without the advisory, every patty must reach 155°F for 17 seconds. Note that undercooked items may not be served to highly susceptible populations.
FDA Food Code §3-603.11Raw oysters are an animal-derived food served raw, so the menu must disclose them and remind guests of the risk of foodborne illness. The other items are fully cooked to their required temperatures and need no advisory.
FDA Food Code §3-603.11Once a whole-muscle cut is stuffed, the whole item becomes a stuffed food and must be cooked to 165°F for 15 seconds. The stuffing sits at the slow-heating center of the food, so the plain pork chop standard of 145°F no longer applies.
FDA Food Code §3-401.11The thickest part of a food is the last to come up to temperature, so that is where the minimum internal temperature must be verified. Checking a thin edge or near the surface can show a passing number while the center is still undercooked.
Fruits and vegetables cooked for hot holding must reach a minimum of 135°F. Once cooked, these plant foods become TCS foods, so they must be brought to and kept at the hot-holding temperature to prevent pathogen growth.
FDA Food Code §3-401.13保温与供餐
40 道题Hot TCS food must be held at 135°F or higher. Holding above this temperature keeps the food out of the danger zone, where pathogens that survived cooking or were reintroduced could multiply.
FDA Food Code §3-501.16With checks every 4 hours, food found out of temperature could have been in the danger zone for up to 4 hours, so it must be discarded. Only a shorter checking interval, such as every 2 hours, leaves time for corrective action like reheating.
FDA Food Code §3-501.16Food found below 135°F at a 2-hour check has been in the danger zone for at most 2 hours, which is within the safe window for corrective action. The food can be reheated to 165°F and returned to holding rather than thrown away, reducing both risk and waste.
FDA Food Code §3-501.16Cold TCS food must be held at 41°F or lower. This keeps the food below the temperature danger zone, slowing the growth of pathogens and the formation of toxins.
FDA Food Code §3-501.16Corrective action for cold food above 41°F depends on knowing how long it was out of temperature. Because that time is unknown here, the food could have been in the danger zone for hours and must be thrown out. The manager should also get the unit checked and log the incident.
FDA Food Code §3-501.16With 4-hour checks, the soup may have sat in the danger zone for nearly 4 hours, long enough for some bacteria to produce heat-stable toxins that reheating cannot destroy. That is why the 4-hour schedule requires discarding food found out of temperature.
FDA Food Code §3-501.16Because the potatoes were checked on a 2-hour schedule, they have been below 135°F for no more than 2 hours, which is within the window for corrective action. Reheating to 165°F destroys pathogens that may have grown, and the potatoes can then go back on the line.
FDA Food Code §3-501.16Lids retain heat, stirring redistributes it so no portion cools below 135°F, and a calibrated probe measures the actual internal food temperature. Equipment dials show water or air temperature, not the food itself, so they can never replace direct temperature checks.
FDA Food Code §3-501.16Under the basic time-as-a-public-health-control option, food removed from temperature control must be sold, served, or discarded within 4 hours. The food must be marked with the discard time, and anything left at 3:00 p.m. must be thrown out.
FDA Food Code §3-501.19The extended 6-hour window applies only to cold food that leaves temperature control at 41°F or below and never rises above 70°F. If the food ever exceeds 70°F, or when the 6 hours expire, it must be discarded.
FDA Food Code §3-501.19Food held under time as a public health control must be marked so staff can tell exactly when its window expires. The marking shows when the food left temperature control and the discard deadline, which is 4 hours later, or up to 6 hours for qualifying cold food.
FDA Food Code §3-501.19Under time as a public health control, the discard time is absolute. Once 4 hours pass, the food must be thrown out regardless of how it looks or feels, and it may not be rescued by reheating or refrigeration because time, not temperature, was the only control.
FDA Food Code §3-501.19The 6-hour option has two simultaneous limits: the clock and the 70°F ceiling. At 73°F the milk has broken the temperature ceiling, so it must be discarded immediately even though the 6-hour window has not expired.
FDA Food Code §3-501.19The Food Code requires written procedures before time as a public health control is used. The procedures describe how food will be marked, monitored, and discarded, and they must be kept in the operation and shown to the regulatory authority on request.
FDA Food Code §3-501.19Time as a public health control only works when the discard time is marked from the moment food leaves temperature control. An unmarked pan cannot be verified, and a cook's estimate is not documentation, so the safe and compliant action is to throw the food out and retrain the team.
FDA Food Code §3-501.19Food on display for self-service must be protected from contamination, and a sneeze guard or similar barrier intercepts droplets and casual contact from guests leaning over the food. It does not control temperature, so cold wells and monitoring are still required.
FDA Food Code §3-306.11Used plates carry saliva and food residue that can contaminate serving utensils and displayed food. Self-service operations must require a clean plate for each return trip; beverage cups may generally be refilled if refilling avoids contact between the dispenser and the cup rim.
FDA Food Code §3-304.17Self-service displays must be labeled so consumers know what they are taking, which also supports allergen awareness. Containers should be washed before refilling; topping off buries older product at the bottom indefinitely.
Dispensing utensils at self-service stations must be stored so their handles stay above the food and out of guests' way of contamination. A long-handled ladle keeps hands away from the soup; standing water breeds bacteria and is not an approved storage method.
FDA Food Code §3-306.13The person in charge must ensure self-service areas are monitored, because barriers alone cannot prevent every contamination event. When a guest eats from the line or misuses utensils, staff must intervene, replace the affected food and utensils, and coach the guest.
FDA Food Code §2-103.11Off-site service depends on maintaining holding temperatures during transport, which requires insulated food-grade carriers for hot and cold items. Temperatures should be checked at loading and again on arrival so any food that fell out of range can be handled before service.
When food will be stored or reheated by someone outside the operation's control, labeling with handling instructions helps the customer keep it safe, including how to reheat it and when to eat or discard it. This extends the operation's food safety management beyond its own walls.
Off-site service still requires the basics of a safe operation: potable water, handwashing capability, waste disposal, and temperature control. Without safe water the crew cannot wash hands or clean utensils, so the manager must arrange potable water or change the plan before serving food.
Hot TCS food must stay at 135°F or above through transport and service. Probing on arrival verifies the transport equipment worked; a reading below 135°F would require corrective action based on how long the food was out of temperature.
FDA Food Code §3-501.16Cold food found above 41°F for a short, documented time can be cooled back down as a corrective action; the risk grows with time in the danger zone, which here was limited and known. If the time were unknown or extended, discarding would be required.
FDA Food Code §3-501.16Without a proper warewashing setup, used tableware cannot be washed, rinsed, and sanitized on site. The caterer must either transport enough clean dishes and utensils for every course or switch to single-use service items.
Food that leaves the kitchen generally may not be re-served once it reaches a guest, but there is a narrow exception for prepackaged items such as wrapped crackers and condiment packets that remain unopened and in good condition. The exposed chili must be discarded.
FDA Food Code §3-306.14Once unpackaged food such as bread has been at a guest's table, the operation cannot verify it was not touched, coughed on, or otherwise contaminated. It must be discarded; appearance is not evidence of safety. Only unopened prepackaged items qualify for re-service.
FDA Food Code §3-306.14Open bowls at guest tables are exposed to double-dipped chips, saliva, and hands, and none of that can be undone by straining, chilling, or freezing. Returned open food must be thrown out, and pouring it into the master batch would contaminate the entire container.
FDA Food Code §3-306.14Re-service is limited to prepackaged items that are still sealed and in sound condition, such as an unopened single-serving bottle. Open ramekins, unwrapped straws, and basket tortillas have all been exposed at the table and must be discarded.
FDA Food Code §3-306.14Ice used for cold holding must surround the product, not just touch the container bottom, and the setup must drain so food does not sit in stagnant meltwater. The measure of success is the food temperature staying at 41°F or below, which staff should verify with a thermometer.
FDA Food Code §3-501.16Any food displayed for customer self-service must be protected by packaging, a counter guard, or another effective barrier, with proper utensils provided. The cook's presence at the station does not shield the open tray from guest coughs, sneezes, and hands.
FDA Food Code §3-306.11Rice held out of temperature control must either be managed under documented time as a public health control with markings, or be rendered non-TCS through an approved acidification process, which typically requires a variance and monitoring records. Holding it with no documentation fails both paths.
FDA Food Code §3-501.19Cold wells only chill product below the fill line; overfilled pans leave the top layers at room temperature. Cut melon is a TCS food, so the manager must fix the fill level and evaluate the out-of-temperature product based on how long it was above 41°F.
FDA Food Code §3-501.16Only a direct internal measurement with a calibrated, sanitized probe confirms the food itself is at 135°F or above. Equipment gauges measure water or air, and visual cues such as steam can appear well below safe holding temperatures.
FDA Food Code §4-302.12Exposed, unpackaged items like open butter pats cannot be re-served. The sealed jam packet qualifies for re-service as an unopened prepackaged item. A condiment squeeze bottle is a serving container that stays in table service and is cleaned and refilled by the operation, not re-served food in itself.
FDA Food Code §3-306.14Food that sat on a self-service buffet has faced hours of temperature stress and potential guest contamination, and the caterer cannot control how it will be handled afterward. A responsible policy is to discard displayed food; never blend served food back with unserved reserves.
Unlike plates, beverage cups may generally be refilled in self-service settings when the dispensing setup keeps the used cup rim from touching the equipment. This is why soda nozzles are mounted above the cup position rather than requiring contact.
FDA Food Code §3-304.17Time as a public health control is a one-way commitment: the food gave up temperature control, so bacteria may have begun growing, and returning it to the cooler does not reverse that growth. The marked discard time stands, and unsold cheese must be thrown out when it expires.
FDA Food Code §3-501.19The Food Code includes a specific allowance: roasts cooked under the roast cooking standards, such as 145°F for 4 minutes, may be held at 130°F or above instead of the usual 135°F. The manager should confirm the roast qualifies and document the holding practice; all other hot TCS foods still require 135°F.
FDA Food Code §3-501.16管理与 HACCP
40 道题Under the Food Code, smoking or curing food as a method of preservation (rather than just for flavor) requires the operator to obtain a variance from the regulatory authority and to keep an approved HACCP plan. The plan must identify the hazards and controls specific to that process because it deviates from standard practice.
FDA Food Code §8-201.13HACCP follows a fixed sequence: Principle 1 is conducting a hazard analysis, Principle 2 is determining critical control points, and Principle 3 is establishing critical limits. The order matters because you cannot set a limit for a control point you have not yet identified, and you cannot identify control points without first analyzing the hazards.
A sewage backflow is an imminent health hazard. The Food Code requires the operation to cease food operations immediately and notify the regulatory authority; service cannot resume until the hazard is corrected and, if required, the regulatory authority approves reopening. Continuing to serve in any part of the facility risks contaminating food.
FDA Food Code §8-404.11Active managerial control means the operation deliberately puts systems in place to control the CDC's foodborne-illness risk factors before problems occur, rather than reacting after the fact. Tools include standard operating procedures, training, monitoring, and corrective actions. The goal is prevention, not damage control.
Reduced-oxygen packaging is one of the specialized processes the Food Code lists as requiring a variance and a HACCP plan, because the low-oxygen environment can favor the growth of anaerobic pathogens such as Clostridium botulinum. Routine grilling, hot holding, and cooling are standard practices that do not require a variance.
FDA Food Code §3-502.11The Food Code requires operators to allow the regulatory authority access to the establishment and to any records the authority is entitled to inspect during normal operating hours. Refusing or delaying entry can itself be a violation. The manager should cooperate, accompany the inspector, and answer questions truthfully.
FDA Food Code §8-402.11Measuring the temperature of each batch to confirm the critical limit is met is monitoring, which is HACCP Principle 4. Monitoring is the planned sequence of observations or measurements used to assess whether a critical control point is under control. Writing down those readings would fall under Principle 7, record-keeping.
When monitoring shows a critical limit was not met, the operation follows its pre-planned corrective action, which is HACCP Principle 5. For undercooked chicken, the corrective action is typically to continue cooking until 165°F is reached and to document the deviation. Corrective actions are decided in advance so staff know exactly what to do.
Verification is HACCP Principle 6: activities, other than monitoring, that confirm the plan is valid and operating effectively. Reviewing logs, calibrating equipment, and periodically validating the plan are classic verification tasks. It answers the question, is the whole system actually doing what we designed it to do?
In a suspected foodborne-illness outbreak, the manager should cooperate fully with the regulatory authority, set aside and label any suspect food so it can be tested, and preserve production and employee-health records. Discarding evidence or stonewalling hampers the investigation and increases liability. Early, honest cooperation protects the public and the business.
When a product is recalled, the operation should stop using it immediately, physically separate it from usable food, and mark it so no one uses it while the operation follows the vendor's or regulator's return or disposal instructions. Keeping it segregated and labeled preserves it for potential inspection and prevents accidental service. Cooking does not make a recalled product safe.
A certified food protection manager has passed a food safety exam from an accredited program, demonstrating the knowledge needed to run a safe operation. The Food Code treats this certification as evidence that the person in charge understands foodborne-illness prevention. Years of experience or ownership alone do not satisfy the requirement.
FDA Food Code §2-102.12An interruption of the potable water supply is an imminent health hazard because staff cannot wash hands, clean, or sanitize properly. The Food Code requires the operation to stop food operations and notify the regulatory authority. Operations may resume only after water service is restored and, where required, the authority approves reopening.
FDA Food Code §8-404.11Management is responsible for training staff on the food safety practices their jobs require, and for verifying that training before employees handle food unsupervised. Ongoing and job-specific training is a core part of active managerial control. Leaving new employees to learn by chance invites the very errors that cause foodborne illness.
A HACCP plan submitted for a specialized process must describe the food and process, typically with a flow diagram, identify the critical control points and their critical limits, and describe monitoring, corrective actions, and record-keeping. These elements let the regulatory authority judge whether the hazards are controlled. Business or marketing information is not part of the food safety plan.
FDA Food Code §8-201.14A fire that disables essential equipment or damages the facility is an imminent health hazard because it can compromise safe food handling and the safety of the premises. Such events require the manager to stop affected operations and notify the regulatory authority. A late delivery or a burned-out bulb are routine issues, not imminent hazards.
Sprouting seeds or beans is one of the specialized processes the Food Code lists as requiring a variance because the warm, moist growing conditions readily support pathogen growth, and sprouts have caused multiple outbreaks. The operation must obtain the variance and typically maintain a HACCP plan. Simply washing produce does not address this specific hazard.
FDA Food Code §3-502.11When an operation ceases because of an imminent health hazard, it generally may not resume until the hazard is eliminated and the regulatory authority approves reopening if such approval is required. This ensures the underlying problem, such as sewage or loss of water, is truly resolved. Reopening on the owner's say-so alone can put the public at risk.
FDA Food Code §8-404.11For a critical violation like an unsafe holding temperature, the manager should correct it immediately, typically by reheating the food to 165°F within the allowed time or discarding it, and then fix why it happened, such as adjusting the steam table. Correcting on the spot demonstrates active managerial control and reduces risk. Arguing or delaying leaves food in the danger zone.
A regulatory authority can suspend a permit and close an operation when conditions present an imminent health hazard, such as an active infestation, lack of hot water for sanitizing, and sewage contamination together. These conditions make safe food handling impossible. Minor issues like an expired spice jar or a cracked tile are corrected through routine follow-up, not closure.
FDA Food Code §8-401.20Reduced-oxygen packaging of food that supports pathogen growth requires an approved HACCP plan or must meet specific Food Code control criteria, because the anaerobic environment can allow C. botulinum to produce toxin if temperature control fails. Relying on refrigeration alone, without the additional barriers and controls the plan specifies, is unsafe. This is exactly why ROP is a variance-triggering process.
FDA Food Code §3-502.12Active managerial control is sustained through written standard operating procedures, documented training, and routine monitoring logs, so every shift follows the same safe practices and problems can be caught and traced. Written systems outlast staff turnover and memory. Relying on a single note or one-time verbal instructions leaves food safety to chance.
The inspection report is the official record of what was found; the manager should review it with the inspector, acknowledge receipt (signing generally means receipt, not agreement), and then correct each violation within the timeframe the report specifies. Following up and documenting corrections is central to the manager's post-inspection role. Ignoring or refusing the report does not make the violations disappear.
FDA Food Code §8-403.10Simply slicing deli meats to order is a routine operation that does not require a variance. In contrast, holding live shellfish in a display tank, custom-processing animals, and using additives or other methods to make a normally hazardous food shelf-stable are all specialized processes the Food Code flags as needing a variance and often a HACCP plan.
FDA Food Code §8-201.13During a power loss, the manager should keep doors closed, track how long food is above 41°F, and check temperatures; TCS food that has exceeded safe temperature or time limits must be discarded. A prolonged outage can itself be an imminent health hazard requiring the operation to stop service and contact the regulatory authority. Guessing or refreezing warmed food risks serving pathogens.
A critical control point is a step where control is essential and can be applied to prevent, eliminate, or reduce a food safety hazard to an acceptable level, such as a cook step that destroys pathogens. Not every step is a CCP; only those where losing control would let a hazard reach the customer. Cost or busyness has nothing to do with it.
The person in charge must actively ensure that employees follow required food safety practices, such as proper handwashing, cooking, and cooling, and must know when to restrict or exclude an ill employee. The PIC's job is oversight of food safety, not doing every task personally. Cash handling and advertising are unrelated to this Food Code duty.
FDA Food Code §2-103.11Shiga toxin-producing E. coli is one of the reportable 'Big Six' pathogens; an employee diagnosed with it must be excluded from the food establishment, and the regulatory authority notified. The employee generally may not return until cleared under the Food Code's reinstatement criteria. Gloves or reassignment do not remove the risk of shedding this pathogen.
FDA Food Code §2-201.11When taking a complaint, the manager should stay calm and record what the person ate, the date and time, the symptoms and when they began, and how to reach the person, while showing concern and not admitting fault. This information helps the operation and the health department investigate a possible outbreak. Asking for payment details or hanging up would be inappropriate and unhelpful.
The Food Code allows an inspector to assess the person in charge's demonstration of knowledge by asking about hazards and controls, such as which pathogen is a concern in a given food and how it is controlled. Correct answers, holding a valid manager certification, or compliance with the Code can satisfy this. It is about food safety competence, not speed or tenure.
FDA Food Code §2-102.11A food safety management system aims to control the CDC's identified risk factors: poor personal hygiene, improper holding and cooking temperatures, contaminated equipment, and food from unsafe sources. Building procedures around these risk factors targets the actual causes of foodborne illness. Layout, specials, and parking are business concerns, not the focus of food safety control.
Record-keeping documents that monitoring occurred and critical limits were met, giving the operation evidence of control that supports verification and, if an illness is reported, an investigation. Good records also reveal trends before they become problems. They never replace monitoring or training; they run alongside them as ongoing proof of a functioning system.
Flooding is an imminent health hazard: floodwater can carry sewage and chemicals that contaminate food and surfaces. The operation must cease operations, discard food and packaging contaminated by the water, and notify the regulatory authority, resuming only when the hazard is corrected and, where required, reopening is approved. Drying out or working around the water does not remove the contamination.
FDA Food Code §8-404.11The last stage of crisis response is learning from the event: analyzing the root cause and revising standard operating procedures, training, and monitoring so the same breakdown cannot recur. This continuous-improvement step turns a crisis into a stronger food safety system. It is not about blaming an individual or escaping future oversight.
For a specialized process like cook-chill with reduced-oxygen packaging, the manager must first secure any required variance and an approved HACCP plan, then train staff to follow it, before the process begins. Doing the paperwork after the fact leaves the operation running an unapproved, higher-risk process. The regulatory authority, not the supplier, grants this approval.
FDA Food Code §3-502.11Organized invoices and lot or code information let a manager quickly determine whether the recalled lot is in the building and remove it before it can be served. Speed matters in a recall, especially a Class I recall involving a serious health risk. Traceability records are a routine but critical part of recall readiness.
Critical limits must be measurable values, such as a temperature, time, or concentration, so that anyone monitoring the step can objectively decide whether the critical control point is under control. Vague limits like 'cook until done' cannot be verified. Measurable limits make monitoring, corrective action, and verification possible.
A boil-water advisory means the tap water may be unsafe, so the operation must switch to bottled or treated water for drinking, ice, and food preparation, or cease operations if it cannot operate safely, following the regulatory authority's instructions. Untreated tap water, including ice made from it, can carry pathogens even if it looks clear. This may function as an imminent health hazard requiring notification.
FDA Food Code §5-101.13Active managerial control means treating a recurring gap as a signal to find and fix the root cause, whether that is understaffing, unclear duties, or a training issue, so the monitoring step is consistently completed. Deleting the log or assigning blame without follow-up hides the problem instead of solving it. The goal is a system that catches and corrects itself.
Operating a molluscan shellfish life-support display tank is a specialized process the Food Code lists as requiring a variance and a HACCP plan, because the tank water and holding conditions can affect the safety of filter-feeding shellfish. The plan must address water treatment, monitoring, and records. A warning sign alone does not satisfy this requirement.
FDA Food Code §8-201.13设施、清洁与虫害
40 道题Cleaning physically removes food residue, grease, and dirt, while sanitizing uses heat or chemicals to reduce the number of pathogens on an already-clean surface to safe levels. A surface must be cleaned before it can be sanitized, because soil shields microbes from the sanitizer. The two steps are distinct and both are required for food-contact surfaces.
For manual hot-water sanitizing in a three-compartment sink, items must be immersed in water maintained at 171°F or hotter for at least 30 seconds. This heat kills pathogens without chemicals. Cooler temperatures such as 110°F or 135°F will not reliably sanitize in that time.
FDA Food Code §4-703.11A chlorine sanitizing solution should be roughly 50 to 100 ppm with water between 55 and 100°F and at least about 7 seconds of contact time. Too little chlorine will not sanitize, and too much can be unsafe and corrosive. Temperature matters because very cold water slows chlorine's action.
FDA Food Code §4-501.114Food-contact surfaces of equipment used with TCS food in continuous operation must be cleaned and sanitized at least every 4 hours to keep pathogen levels from building up. Waiting until the end of the day or until soil is visible allows bacteria to grow between uses. More frequent cleaning is required when contamination is likely.
FDA Food Code §4-602.11An air gap, an unobstructed vertical space between a water outlet and the flood rim of the receiving fixture, is the most reliable backflow prevention because there is no physical connection for contaminated water to travel back through. The gap should generally be at least twice the diameter of the supply opening and never less than one inch. Mechanical devices help but can fail; an air gap cannot be back-siphoned.
FDA Food Code §5-202.13A high-temperature dish machine typically must reach at least 180°F at the final rinse manifold so that the dish surface reaches about 160°F, which is hot enough to sanitize. If the rinse is too cool, items are washed but not sanitized. Managers should verify the rinse temperature with the machine gauge or a heat-sensitive indicator.
FDA Food Code §4-501.112Toxic materials such as cleaners and pesticides must be stored in a designated area away from food, equipment, utensils, and single-service items, and ideally below them so they cannot spill or drip onto food. Storing chemicals above or among food invites contamination. Working containers must also be clearly labeled with the product's common name.
FDA Food Code §7-201.11The proper sequence is to first scrape or pre-rinse the item, wash in the first compartment with detergent and water at 110°F or hotter, rinse in the second compartment with clean water, sanitize in the third compartment, and then air dry. Towel drying or stacking wet can recontaminate items. Air drying prevents wiping sanitizer off and adding new contamination.
IPM rests on denying pests entry, food and water, and shelter, so the environment simply does not support them; chemical treatment is a last resort performed by a licensed pest control operator. Routine daily spraying, luring pests with food, or propping doors open all work against these principles. Prevention through exclusion and sanitation is far more effective than reacting with pesticides.
FDA Food Code §6-501.111Quaternary ammonium sanitizer must be mixed to the manufacturer's specified concentration, commonly about 200 ppm, and confirmed with a quat-specific test kit. Concentrations for quats differ from chlorine, so chlorine's 50 to 100 ppm range does not apply. Guessing by appearance or overdosing wastes product and can leave unsafe residue.
FDA Food Code §4-501.114Iodine sanitizers, or iodophors, are effective at roughly 12.5 to 25 ppm within the manufacturer's specified temperature and pH range. This range is much lower than chlorine or quats, so using a chlorine test strip or a higher target would be wrong. Always check the specific product label and verify with the matching test kit.
FDA Food Code §4-501.114Signs of a cockroach infestation include a strong, oily odor, droppings resembling ground pepper, and egg capsules (oothecae) tucked into cracks and crevices. Spotting these means the manager should clean thoroughly, eliminate harborage, and bring in a licensed pest control operator. Clean shelves, good lighting, and a working air gap are signs of a well-maintained facility, not infestation.
FDA Food Code §6-501.11Any working container that a chemical is transferred into must be labeled with the common name of that chemical, so no one mistakes it for something else. Unlabeled or mislabeled containers are a leading cause of chemical-contamination incidents. Reusing food containers for chemicals is prohibited because it invites dangerous mix-ups.
FDA Food Code §7-102.11Denying pest access means outer openings must be protected: exterior doors self-closing and tight-fitting, open windows screened, and gaps around utility lines and pipes sealed. Even a small gap under a door or an open, unscreened window is an invitation to rodents and insects. Exclusion at the building envelope is the first line of an effective pest program.
FDA Food Code §6-202.15A master cleaning schedule documents every cleaning task in the operation: the item or area, the person responsible, the frequency, and the method and chemicals to use. This ensures both obvious and easily forgotten areas are cleaned consistently across shifts. It turns cleaning from a guessing game into a managed, verifiable system.
Multiuse food-contact surfaces must be smooth, durable, nonabsorbent, corrosion-resistant, and easy to clean so they can be effectively cleaned and sanitized and do not harbor pathogens. Absorbent, rough, or raw-wood surfaces trap moisture and food and cannot be reliably sanitized. Choosing the right construction materials is a foundational facility-design decision.
FDA Food Code §4-101.11A hose submerged in dirty water creates a cross-connection: if pressure drops, back-siphonage can pull the contaminated water into the potable plumbing. This is exactly the scenario backflow prevention devices and air gaps are meant to stop. Hoses should never be left in standing water, and a backflow preventer or air gap should protect the connection.
FDA Food Code §5-402.11The wash solution in a manual warewashing sink must be kept at least 110°F, hot enough for the detergent to cut grease and lift soil. Water that is too cool will not clean effectively, leaving residue that shields microbes from the sanitizer. The 171°F figure applies only to hot-water immersion sanitizing, not the wash step.
FDA Food Code §4-501.19Adequate lighting, with higher intensity required at food-prep and warewashing areas and where equipment is cleaned, lets staff see soil, pests, and spills and work safely. Poorly lit areas hide dirt and contamination and increase accidents. The Code specifies minimum foot-candle levels precisely so critical work areas are bright enough to keep clean.
FDA Food Code §6-303.11Garbage receptacles should be covered with tight-fitting lids when not in continuous use, and emptied and cleaned frequently so they do not overflow, smell, or attract pests. Overflowing or uncovered garbage is a magnet for rodents and insects. Keeping refuse areas clean, indoors and in the outdoor dumpster area, is a core part of pest prevention.
FDA Food Code §5-501.113Food-contact surfaces must be cleaned and sanitized before switching from raw animal food to ready-to-eat food, in addition to the every-4-hour continuous-use rule. Using the same unwashed board and knife transfers pathogens from raw chicken directly onto food that will not be cooked. The fix is to clean and sanitize, or use separate color-coded equipment.
FDA Food Code §4-602.11A hose connection is a common backflow risk, so an approved backflow prevention device such as a vacuum breaker is installed to stop contaminated water from being siphoned back into the potable system. When a permanent air gap is not feasible, a mechanical device like a vacuum breaker is the accepted protection. Grease traps and drains serve entirely different plumbing functions.
FDA Food Code §5-203.14All water used in a food establishment for drinking, food preparation, warewashing, and handwashing must come from an approved public water system or an approved, tested private source, meaning it is potable. Appearance is not a safe test; water can look clear and still carry pathogens or chemicals. Non-potable water may only be used for restricted purposes like some irrigation, never for food contact.
FDA Food Code §5-101.11Gnaw marks, greasy rub marks, and droppings are classic signs of a rodent infestation. The manager should throw out any food that may be contaminated, clean and sanitize affected areas, and bring in a licensed pest control operator to identify the entry points and treat the problem. Ignoring the signs or feeding the pests only lets the infestation grow.
At 200 ppm the chlorine concentration is above the effective 50 to 100 ppm range, which can be corrosive, leave residue, and is not necessary for sanitizing. The manager should add water to dilute it back into range and retest. Too-strong sanitizer is a real hazard, not extra insurance, so accurate mixing and testing matter.
FDA Food Code §4-501.114Nonfood-contact surfaces must be cleaned often enough to prevent buildup of dust, dirt, food debris, and grease, which can attract pests and harbor soil, but they do not require the same every-use sanitizing that food-contact surfaces do. Regular attention to legs, shelves, and hood exteriors keeps the whole environment sanitary. Neglecting them invites pests and cross-contamination even if the food-contact surfaces are clean.
FDA Food Code §4-602.13Heat sanitizing works by exposing items to a high enough temperature, 171°F, for long enough, at least 30 seconds, to destroy pathogens. If the water is cooler or the time shorter, sanitizing fails even though the items look clean. That is why a thermometer and a timer, or a monitored heat source, are essential at a hot-water sanitizing sink.
FDA Food Code §4-501.111Dead pests must be removed from the establishment promptly, and the areas where they were found cleaned and sanitized, because carcasses and debris can contaminate food and surfaces. Leaving them, even as evidence of a successful treatment, is a sanitation violation. Prompt removal is a standard follow-up step after any pest treatment.
FDA Food Code §6-501.112In areas subject to moisture and food debris, floors, walls, and ceilings must be built of smooth, durable, nonabsorbent, and easily cleanable materials so they can be kept clean and do not harbor moisture or pests. Carpet, cracked concrete, or porous wood absorb spills and are impossible to sanitize. Correct construction materials are a first-line defense against contamination and pests.
FDA Food Code §6-101.11Denying pests food and water means cleaning spills promptly, keeping food in tightly sealed containers stored off the floor, and repairing plumbing leaks that provide moisture. Standing water, exposed food, and dirty dishes are exactly what draw pests in. Good sanitation is one of the strongest tools in an IPM program, well before any pesticide is needed.
A licensed pest control operator has the training and legal authorization to choose the right products, apply them safely around food, and store them properly, minimizing the risk of chemical contamination. Untrained staff can misapply pesticides and contaminate food or surfaces. Using a PCO is the accepted practice within an Integrated Pest Management program.
To confirm a high-temperature machine is sanitizing, the manager should verify that the dish surface actually reaches about 160°F, using a maximum-registering thermometer or a heat-sensitive label run through the machine. The built-in gauge shows manifold temperature but can be inaccurate, so independent verification matters. Touching dishes by hand is neither safe nor a valid measurement.
FDA Food Code §4-501.112A handwashing sink must be used only for washing hands and must be kept accessible and stocked at all times, so staff are never discouraged from washing up. Using it to rinse mops or thaw food blocks and contaminates it, undermining hand hygiene. Mop water goes to a service or mop sink, and food is thawed by approved methods, never in the handwashing sink.
FDA Food Code §5-205.11Plumbing must be designed, installed, and maintained so it does not leak, back up, or create contamination or pooling water. A leaking drain must be repaired promptly because standing wastewater contaminates surfaces and attracts pests. Buckets, mats, or redirecting the leak are not acceptable substitutes for a proper repair.
FDA Food Code §5-205.15The only reliable way to confirm sanitizer concentration is to measure it with the test kit made for that specific sanitizer, chlorine, quat, or iodine, and document the reading. Smell, color, and trust are not measurements and can be badly wrong. Routine testing and recording is part of active managerial control over warewashing.
Chemical sanitizers work based on concentration, water temperature, contact time, water hardness and pH, and how clean the surface is; soil on the surface can neutralize the sanitizer. The color of the sink basin has no effect on sanitizing. Managers must control the real variables, especially concentration, temperature, and time, to sanitize effectively.
FDA Food Code §4-501.114Storing a chemical above food risks spills or drips contaminating the flour, a serious chemical-hazard error. The fix is to store all toxic materials in a designated area that is separate from and below food, equipment, and single-use items. Simply tightening a cap or swapping which item is on top does not eliminate the contamination risk.
FDA Food Code §7-201.11Cleaned and sanitized items must be allowed to air dry; wiping with a towel or stacking while wet can recontaminate the surfaces you just sanitized. Trapped moisture between stacked wet items can also let bacteria grow. Air drying on a clean, drained surface is the correct, contamination-free final step.
FDA Food Code §4-901.11An air gap must be at least twice the diameter of the water supply inlet, and in no case less than one inch, measured vertically between the outlet and the flood rim of the receiving fixture. Too small a gap can allow back-siphonage of contaminated water. This simple physical measurement is what makes the air gap the most reliable backflow protection.
FDA Food Code §5-202.13A useful master cleaning schedule lists what to clean, who does it, how often, and the method and chemical or sanitizer to use, so the task is done correctly and consistently. The retail price of the chemical is a purchasing detail, not something staff need to perform the cleaning safely. Focusing the schedule on the actionable how, who, and when makes it a practical tool.
