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.

Running 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.

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, 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.

Cooking 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.

Microwave 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.

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.

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.

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.

Stuffed 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.

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.

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.

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. If eggs are pooled or will be held for later service, the higher standard of 155°F for 17 seconds applies instead.

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. No specific hold time is required for plant foods at this temperature.

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.

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 temperature should still be verified with a thermometer after the stand time.

Stuffed 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.

The 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.

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. 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.

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. 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.

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.

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.

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. Cooling food should be portioned shallow 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.

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.

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. Shallow panning in a walk-in is an approved combination of methods. 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. 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.

Steam 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.

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 165°F within 2 hours rule applies when reheated food will go into hot holding.

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.

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. 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 items are fully cooked to their required temperatures and need no advisory.

Once 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.

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. 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.
