58 道题Proper 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. Soap needs water and friction, so applying it to dry hands, or scrubbing and then skipping the rinse, does not clean them, and drying before washing accomplishes nothing. Cold water with no soap does not lift soil, and an apron or a shared cloth towel recontaminates hands that were just rinsed.
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. A pocketed phone is handled constantly and is not clean, gloves worn during an earlier step do nothing for the contacts that follow them, and the carnitas do not have to be touched by the phone directly — the hands carry it.
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 menu, a no-smoking sign moved from the dining room, and a morale poster all put words above the sink without giving the handwashing reminder the Code asks for.
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 counter, on the line, in the walk-in or dry store, or over open containers risks contaminating food, equipment, and clean utensils with saliva, crumbs, and hand-to-mouth pathogens. A short break does not turn a food area into an eating area, and a later cook step does not license dropping crumbs into the food now.
FDA Food Code §2-401.11Hands must be washed and dried immediately before putting on single-use gloves, because gloves pulled over dirty hands can be contaminated during use and through small tears. Gloves are a supplement to, not a replacement for, handwashing. Dipping the gloves in sanitizer treats the outside while the hands underneath stay soiled, and a cloth towel kept at the station transfers contamination back to hands that were never washed.
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. Pulling fresh gloves over unwashed hands leaves the pathogens on the skin underneath, and wiping on a towel only moves them around, however clean the towel is. 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. The other three all happen after any cook step: cold-cut sandwiches, dessert garnishes, and herbs torn onto a finished dish are ready-to-eat and need gloves, tongs, or deli tissue no matter how the item was processed upstream, and a garnish laid on a plated dessert is served and eaten with it. 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. Beards shed regardless of how coarse or well-trimmed they are, so doing nothing is incorrect. A baseball cap restrains head hair only and leaves the beard exposed, and the Code asks for an effective restraint, not for the beard to be shaved off.
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. A slow shift still has restroom trips and raw-food contacts, and the pathogens that matter most are invisible, so waiting for visible soil misses them. A fixed timer washes at the wrong moments — too late after a contamination event and pointlessly when nothing happened.
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. A diagnosed handler sheds the pathogen whether or not symptoms have started, so waiting for diarrhea is too late; gloves and a move to the dish pit both keep an excludable person inside the operation, where hands still reach clean equipment. 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. Tape, gloves pulled over the bands, and a long sleeve all leave the jewelry on the arm, so the hands still cannot be washed properly and the bands still cannot be cleaned; wiping them with sanitizer does not make a bracelet a food-prep item. The items must simply be removed.
FDA Food Code §2-303.11The stem asks for the MOST important reason, and it is a food-safety one: the fecal-oral route is how many of the most dangerous foodborne pathogens spread, including Norovirus, Shigella, Hepatitis A, and STEC, so washing after the restroom breaks that route. Odour, a dress code, and what guests can see from the dining room are all appearance or policy reasons; each may be true of a workplace, but none of them is why the Food Code makes this wash mandatory. That is also 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 that same asymptomatic diagnosis may be restricted rather than excluded — restriction is the wrong answer here only because of the highly susceptible population in the stem, which raises the standard to exclusion. The diagnosis itself, not the appearance of symptoms, is what triggers the action, so letting the handler work normally or waiting for symptoms 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 only covers odour and does nothing to a pathogen, and gum-chewing is prohibited in prep areas because it moves saliva to the hands and food. Long polished nails harbor pathogens and can chip into food, so the Code keeps nails short, clean, and unpolished unless gloves are worn.
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. Raw juices reach the skin around and inside the gloves, so swapping gloves without washing leaves contaminated hands underneath, and cold water with no soap does not lift or kill what is on them. The quesadillas were cooked before this contact and will not be cooked again, so contamination added now reaches the guest.
FDA Food Code §2-301.14A handwashing sink must be maintained so that it is accessible at all times for employee use, and it may not be used for any purpose other than handwashing. Blocking it with pans is the same violation as filling it with thawing shrimp or dumping mop water in it: the sink stops being available at the moment a cook needs it.
FDA Food Code §5-205.11Each handwashing sink needs a cleaning compound, an approved drying provision such as disposable towels or a hand dryer, a waste receptacle where towels are used, and a sign telling employees to wash their hands. A shared cloth towel recontaminates hands, and gloves or sanitizer are not a substitute for the station's required supplies.
FDA Food Code §6-301.11The Supplement replaced the requirement for two consecutive negative stool cultures with two consecutive negative laboratory test results from a validated test, run by a laboratory accredited or certified to handle clinical specimens. That opens the door to modern culture-independent methods while keeping the same two-negative standard, and a self-declaration has never met it.
Supplement to the FDA Food Code 2022, §2-201.13An asymptomatic Norovirus diagnosis calls for restriction in an operation that does not serve a highly susceptible population, which means the employee may not work with exposed food, clean equipment, or unwrapped single-service articles. The same diagnosis in a hospital or nursing home kitchen would require full exclusion instead.
FDA Food Code §2-201.12In an operation serving a highly susceptible population, an asymptomatic diagnosis of Shiga toxin-producing E. coli, Shigella, or Norovirus requires exclusion, not restriction. Guests in a nursing home can be severely harmed by a very small dose, so the Food Code removes the employee from the establishment rather than limiting his tasks.
FDA Food Code §2-201.12Single-use gloves are used for only one task and must be discarded when they are damaged or soiled, or when an interruption occurs in the operation. Hands are washed before a new pair goes on, because rinsing, wiping, or spraying a glove leaves whatever the cook touched during the interruption on the surface that will touch food.
FDA Food Code §3-304.15Food employees must clean their hands before donning gloves to start a task that involves working with food. A glove pulled over dirty hands transfers contamination to the outside of the glove as it is stretched on, which is why gloves are an addition to handwashing rather than a replacement for it.
FDA Food Code §2-301.14A slash-resistant glove used to protect the hands during cutting may be in direct contact only with food that is subsequently cooked, such as frozen food or a primal cut of meat, because the mesh cannot be cleaned and sanitized like a smooth surface. To handle ready-to-eat food, the butcher covers it with a smooth single-use glove.
FDA Food Code §3-304.15Food employees with service animals may handle or care for their own animals as long as they wash their hands afterward. Handwashing is also required after caring for aquarium fish or shellfish in a display tank, and it is the specific control the Code names for animal contact.
FDA Food Code §2-403.11A food employee with persistent sneezing, coughing, or a runny nose causing discharges from the eyes, nose, or mouth may not work with exposed food, clean equipment, clean utensils and linens, or unwrapped single-service articles. This is separate from the five reportable symptoms, and no amount of handwashing removes the droplets.
FDA Food Code §2-401.12A food employee may drink from a closed beverage container if it is handled so it does not contaminate hands, the container, exposed food, clean equipment, or unwrapped single-service articles. Open cups and opened cans let condensate, splash, and hand contact reach food, so they are not permitted in prep areas.
FDA Food Code §2-401.11Employees may eat, drink, or use tobacco products only in designated areas where contamination of exposed food, clean equipment, utensils, linens, and unwrapped single-service articles cannot result. A quiet corner of the cook line, a dry storage room, and the dish machine all fail that test regardless of how slow the shift is.
FDA Food Code §2-401.11Handwashing is required after handling soiled equipment or utensils, because dirty pans carry food soil and the bacteria growing in it. A rinse without a cleaning compound does not meet the twenty-second procedure, and pulling gloves over contaminated hands moves the problem to the glove surface.
FDA Food Code §2-301.14The Code lists handwashing when switching between working with raw food and working with ready-to-eat food, along with after using the toilet, after handling soiled equipment, after coughing or eating, and before donning gloves. Clocking out, stocking napkins, and filling in a log are not on that list.
FDA Food Code §2-301.14A hand antiseptic may be applied only to hands that have already been cleaned by the full handwashing procedure, so sanitizer is an addition, never a replacement. Alcohol gel also works poorly through food soil and does little against Norovirus, which is the pathogen this cook is most likely carrying to the fruit.
FDA Food Code §2-301.16Unless intact gloves in good repair are worn, a food employee may not wear fingernail polish or artificial nails when working with exposed food, and nails must be trimmed, filed, and maintained so the edges are cleanable. Polish chips into food and artificial nails trap soil where a nail brush cannot reach.
FDA Food Code §2-302.11An employee excluded for vomiting or diarrhea without a diagnosis may be reinstated once she has been asymptomatic for at least 24 hours, or once she gives the person in charge written medical documentation that the symptom came from a noninfectious condition. Working a different station does not shorten that window.
FDA Food Code §2-201.13The alternative that lets food employees touch exposed ready-to-eat food with bare hands is available only with prior approval from the regulatory authority and only where a highly susceptible population is not served, so a hospital cafeteria can never use it. Training and antiseptic do not change that restriction.
FDA Food Code §3-301.11收货与储存
67 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. Organic certification, warehouse distance, and the lowest bid are business or marketing considerations, not food safety controls — a certified-organic or nearby supplier can still be an unapproved source. 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, which runs from 41°F to 135°F. A load arriving at 125°F, 130°F, or 110°F has already 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. A cold case, rock-hard shrimp that still rattle loose instead of being frozen into a block, and a label listing the harvest date, lot code, and plant number 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 in refrigerated equipment at an ambient air temperature of 45°F or below — a specific allowance recognizing how shellstock is shipped — and must then be cooled to 41°F or below within four hours. Note the two figures are different rules for the same food: 45°F is the AMBIENT limit, while shellstock's INTERNAL temperature may be as high as 50°F on receipt. Requiring 41°F or 32°F ambient is stricter than the Code.
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 back to the harvest source. Discarding the tag 24 hours after the container is emptied is far too short for traceback; the 7-day figure is the date-marking limit for ready-to-eat food, not the tag-retention rule; 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. An ambient 55°F or 50°F is too warm to meet that rule. A cooler running at 41°F would also satisfy it, but the question asks what the Code requires, and the Code's shell-egg allowance is an ambient 45°F — so naming 41°F as the only acceptable figure states the rule incorrectly. 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 it is promptly cooled. Milk is one of the items the Code gives a special receiving allowance, so a 45°F arrival is not grounds to reject it or to discard it as adulterated. It also cannot ride out the carton's sell-by date at 45°F, because 45°F is inside the danger zone.
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, so opening it first or wiping it and rotating it into service is exactly wrong. An intact, legible label does not make a seam-dented or swollen can safe, and a swollen can must never be 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. Cold crisp lettuce, a sealed lot-coded bag of flour, and squarely stacked cases with nothing crushed or leaking are all signs of an acceptable load, not grounds for rejection. 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 twice the limit, and starting the count the day after opening also stretches it. Same-day discard is stricter than the Code requires, and the manufacturer's sell-by date does not replace the date mark once the container is opened. 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. Taking the later date, restarting the 7-day count on the day of mixing, or dropping the date mark entirely would all let the older batch 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, the one with the soonest use-by or expiration date, is used first, so newer deliveries are stored behind or beneath existing stock. Using the newest delivery first leaves old product on the shelf to spoil or expire. FIFO is a rotation rule, not a rule about how much inventory to carry or about grouping product by color; it reduces waste and prevents serving out-of-date food.
Ready-to-eat foods and washed produce go on the top shelf, above all raw animal foods, so raw juices cannot drip onto them. Raw animal foods are stored below in order of their minimum cooking temperature, with poultry lowest. Sealed pans, covered tubs, and deep pans do not change that order: placing raw chicken, ground beef, or pork above ready-to-eat food still risks dripping pathogens onto it if a container leaks.
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. Cut fruit and washed salad greens are ready-to-eat, so they go on top, then raw seafood and shellfish, then whole beef, pork, or lamb cuts, 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 of clearance is not enough, storing directly on the floor is prohibited even for boxed goods, and 24 inches is more than the Code requires. Shelving must also be smooth, cleanable, and away from walls where practical.
FDA Food Code §3-305.11
