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. Refrigeration is not the only approved method. Standing water that has been warmed and prep counters at room temperature are never approved because the outer layers of the food would sit in the temperature danger zone, and microwave-thawed chicken may not be held overnight before cooking.

Running water used for thawing must be drinkable and at 70°F or lower, and it must flow fast enough to carry loose food particles into the overflow. The stem asks for the maximum allowed, so 41°F and 60°F are not the answer even though colder water is acceptable to use. Water at 135°F would raise the surface of the shrimp into the temperature danger zone while the center is still frozen, allowing pathogens to grow.

Thawing under refrigeration at 41°F or lower keeps the food out of the temperature danger zone for the entire process and requires no monitoring, which is what the stem asks for. Microwave thawing is approved only when cooking continues immediately, so the loins could not be held in the cooler until the next day. Standing water is not running water, and ambient thawing near the cookline is never permitted.

Cooking food from its frozen state is one of the four approved thawing methods, so no separate thawing step is required and no product category is excluded. The control is the internal temperature of the tenders, which must reach 165°F for <1 second (instantaneous) for poultry — not the temperature of the fryer oil, and not a prior pass through the microwave.

Microwave thawing partially heats the food and can bring portions of it into the temperature danger zone. Food thawed in a microwave must therefore move directly into the cooking process, with no holding, storage, rinsing, or resting in between. The 2-minute standing time belongs to microwave cooking of raw animal foods, not to microwave thawing.

When 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 — covered or uncovered. Raw ground turkey is not a ready-to-eat food, and simply being slower than refrigerated thawing is not a food safety reason.

Working 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. Batch size does not control allergen cross-contact, which is prevented by separation and by cleaning and sanitizing surfaces, and portion consistency and dishwashing load are quality or labor concerns rather than food safety controls.

Correct small-batch prep keeps most of the product at 41°F or lower while only a workable amount is on the table, and each finished batch goes back to refrigeration immediately, so no portion accumulates significant time in the temperature danger zone. Bringing all 40 pounds out at once leaves the whole case warming; a propped cooler doorway is not refrigeration and does not hold fish at 41°F; and staging fish next to the cookline puts it in the hottest part of the kitchen.

Poultry must reach a minimum internal temperature of 165°F held for <1 second (instantaneous), and the Food Code makes no distinction between light and dark meat. At 158°F the thigh has not met the requirement, so cooking must continue and the temperature must be rechecked in the thickest part. There is no 175°F standard in the Code, resting on the plate is not a substitute for reaching 165°F, and 155°F for 17 seconds is the ground-meat line of the chart.

Stuffed foods and stuffing, including stuffed pasta, must be cooked to 165°F for <1 second (instantaneous). The dense interior heats slowly and can shelter pathogens, so the highest cooking standard applies regardless of whether the filling contains meat. The 145°F, 155°F, and 135°F lines of the chart are real standards for other foods — whole cuts and seafood, ground meats, and plant foods for hot holding — but none of them cover a stuffed item.

Grinding 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. 165°F for 15 seconds is the reheating standard for TCS food going into hot holding, and 135°F is a hot-holding temperature, not a cooking temperature for raw ground beef.

Mechanically 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. The Food Code does not move tenderized beef up to the 165°F poultry and stuffed-food line, and 135°F is a hot-holding temperature rather than a cooking temperature for raw beef.

Whole-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.

Seafood, 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.

Shell eggs cooked to order and served immediately must reach 145°F for 15 seconds, the same line of the chart as seafood and whole cuts of meat. If eggs are pooled or will be held for later service, the higher standard of 155°F for 17 seconds applies instead. 165°F is the poultry and stuffed-food temperature, and 135°F is a hot-holding temperature rather than a cooking temperature for raw shell eggs.

Whole 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.

Fruits and vegetables that will be hot-held must be cooked to at least 135°F, which matches the minimum hot-holding temperature, and no specific hold time is required for plant foods at this temperature. 155°F for 17 seconds is the ground-meat standard, 145°F for 15 seconds covers seafood and whole cuts, and 165°F for 15 seconds is the reheating standard for TCS food going into hot holding — the green beans here are being cooked fresh, not reheated.

Raw 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, and this standing time is part of the cooking rule itself, not a reheating rule. Neither 155°F nor 145°F meets the requirement for raw poultry.

Microwave 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 standing time never replaces the thermometer — the temperature must still be verified after the stand — and container safety and eating quality are not the food safety reason for the rule.

Stuffed foods, including stuffed shrimp, must be cooked to 165°F for <1 second (instantaneous), the highest standard on this list. The ribeye and the halibut require 145°F for 15 seconds, and the ground lamb and beef skewers require 155°F for 17 seconds because grinding spreads surface bacteria through the meat.

The first cooling stage requires food to drop from 135°F to 70°F within 2 hours, so the clock for the chili runs from 3:00 to 5:00 p.m. This stage is the most critical because bacteria grow fastest in the upper part of the danger zone. The 6-hour figure is the total cooling window from 135°F to 41°F, not the first-stage deadline the stem asks about; the 4 hours belong to the second stage, from 70°F to 41°F; and the Code sets no 1-hour first stage.

Once 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.

The sauce failed the first cooling stage because it did not reach 70°F within 2 hours. Once that stage is missed the remaining 4 hours are no longer available, a 30-minute recheck is not an approved delay, and moving the pot to the freezer does not restart or extend the clock. 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.

An 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. Cold tap water is far warmer than an ice slurry, and bagged ice against a covered pot left unstirred barely moves heat out of the center. Floating ice on soup left on the counter is not an ice-water bath at all; using ice as an ingredient is a separate approved method that has to be built into the recipe.

Dividing 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. Deep pans are not restricted to hot holding, date marking does not depend on pan depth, and stacking pans tightly blocks the airflow that cooling relies on.

An 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. A gel mat, an ice scoop, and a metal skewer are not ice paddles, and none of them move heat out of the center of a batch the way stirring does.

Deep 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. The other three choices are approved ways to speed cooling: cooling food should be portioned shallow, stirred or ice-paddled, and left loosely covered or uncovered, protected from contamination, until it reaches 41°F.

Using 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. Adding boiling water adds heat instead of removing it, a freezer is not an approved cooling method for a full hot pot because it warms the freezer and barely reaches the core, and cooling on the counter at room temperature is never permitted.

Cutting 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. An hour on the counter spends that limit in the danger zone, floor storage is prohibited because food must be kept up off the floor, and foil traps the heat it is meant to release.

The 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. The overall window is 6 hours, not 4, and shallow panning in a walk-in is an approved combination of methods rather than a prohibited one. Cooked rice is a TCS food, so these limits absolutely apply.

Food that was cooked, cooled, and will be hot-held must be reheated to 165°F, and the reheating must be completed within 2 hours. 145°F for 15 seconds is a cooking temperature for whole cuts, not a reheating standard; a steam table only maintains temperature and cannot bring food up fast enough; and properly cooled leftovers may certainly be reheated. Reheating quickly through the danger zone destroys any pathogens that may have grown during cooling and storage.

Commercially 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, so it is the wrong rule here. Cheese sauce is a TCS food once opened, so it cannot be parked in a hot well unheated or simply held cold when the plan is to serve it hot.

Steam tables and other hot-holding units are designed to maintain temperature, not raise it quickly, so they may not be used for reheating and cannot be trusted to carry food through the danger zone. Thawing in the well is worse still, and 145°F is a cooking temperature for whole cuts, not the reheating standard. 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.

The 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 key word in the stem is immediate: the 165°F within 2 hours rule applies when reheated food will go into hot holding, and 135°F is a holding minimum, not a reheating rule. Nothing requires leftovers to be reheated in full batches.

A 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. Supplier names, receiving dates, photographs, certification numbers, and nutrition figures belong to other requirements or to none at all, and no combination of them satisfies the advisory.

An 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. Grinding in house does not lower the required cook temperature, and a signed waiver is not recognized by the Food Code. Note that undercooked items may not be served to highly susceptible populations.

Raw 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 three are fully cooked to their required temperatures, and the stir-fry is not even animal-derived, so none of them needs an advisory.

Once a whole-muscle cut is stuffed, the whole item becomes a stuffed food and must be cooked to 165°F for <1 second (instantaneous). The stuffing sits at the slow-heating center of the food, so the plain pork chop standard of 145°F no longer applies, and stuffing a chop does not turn it into a ground product at 155°F. A hot-holding temperature is never a substitute for a cooking temperature.

The thickest part of a food is the last to come up to temperature, so that is where the minimum internal temperature must be verified. The word to notice in the stem is thick: checking a thin edge, the browned surface, or the grill grate itself can show a passing number while the center of the breast 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. Baking does not make a dish a stuffed food requiring 165°F, and nothing prevents cooked fruit from being hot-held.

The Food Code chart for ratites and non-intact meats lists 145°F for 3 minutes, 150°F for 1 minute, and 158°F for less than 1 second as equivalents to 155°F for 17 seconds. Thirty seconds at 145°F is far short of the required hold, and 140°F and 135°F are below the lowest temperature the chart allows no matter how long they are held.

Ground turkey is poultry, and the Food Code sets poultry — whole or comminuted — at 165°F for <1 second (§3-401.11(A)(3)). Grinding does not move it: the 155°F/17-second row covers comminuted MEAT and fish, not poultry. The 150°F/1-minute pairing is not a comminuted rule at all — it comes from the whole-meat roast table in §3-401.11(B), which never applies to poultry. Read the food type first, then the form: the type decides which table you are in.

Ratites such as ostrich and emu are cooked to 155°F for 17 seconds, the same group as non-intact meats and comminuted fish and game. Whole-muscle fish and intact meat use 145°F for 15 seconds, while poultry and stuffed foods use 165°F instantaneously.

Grinding moves surface organisms throughout the product, so comminuted fish joins non-intact meats at 155°F for 17 seconds. A whole cod fillet is intact and cooks to 145°F for 15 seconds, which is exactly why the same fish carries two different requirements depending on how it was cut.

Stuffing containing fish, meat, poultry, or ratites is cooked to 165°F instantaneously, the same requirement as poultry itself, because a dense stuffing insulates its center and shields any organisms carried in by the meat. A plain bread dressing with no animal food would be a plant food cooked for hot holding at 135°F.

The whole-roast chart pairs 130°F with a 112-minute hold, 135°F with 36 minutes, 140°F with 12 minutes, and 145°F with 4 minutes. The lower the temperature, the longer the hold, and holding time may include the post-oven heat rise as the roast rests.

A still dry oven must be preheated to and held at 350°F or more for a roast under 10 pounds, while a convection oven uses 325°F or more for that weight. Roasts of 10 pounds or more may use 250°F or more, and a high-humidity oven runs at 250°F or less.

Non-continuous cooking requires an initial heating process no longer than sixty minutes, followed immediately by cooling under the standard cooling parameters and cold or frozen storage until the final cook. The operation also needs written procedures approved in advance by the regulatory authority.

A raw or undercooked whole-muscle intact beef steak may be served if the operation does not serve a highly susceptible population, the steak is prepared so it stays intact, and both the top and the bottom reach a surface temperature of 145°F or above with a cooked color change on all external surfaces. The interior may remain rare because an intact steak carries organisms only on the outside.

Fish served raw must be frozen and stored at -4°F or below for a minimum of 168 hours, which is 7 days. The two alternatives both start at -31°F: frozen solid then stored at -31°F for 15 hours, or frozen solid then stored at -4°F for 24 hours.
