The FDA Food Code 2026 Two-Inch Uncovered Cooling Method

The FDA Food Code 2026 adds a specific cooling option for cooked time/temperature control for safety (TCS) food: an establishment may, if approved, place food no more than two inches deep, uncovered, in a refrigeration unit at 41°F or below that continuously monitors time and ambient air temperature. It is not a blanket instruction to leave food uncovered in any refrigerator. Approval and the equipment conditions are essential.

This option sits alongside the ordinary cooling methods in §3-501.15, such as shallow pans, smaller portions, rapid-cooling equipment, ice-water baths, heat-transfer containers, or ice as an ingredient. Every method still must meet the cooling time and temperature limits in §3-501.14.

The cooling limits still apply

Cooked TCS food generally must cool from 135°F to 70°F within two hours and then to 41°F or below within a total of six hours. Food prepared from ambient-temperature ingredients has a separate four-hour cooling limit to 41°F or below. The two-inch method does not extend those clocks or change the target temperatures.

Start the clock when the food enters the cooling phase at the temperature defined by the code. Measure the warmest part of the food, not just the refrigerator display. A cold air reading does not prove that the center of a deep pan cooled quickly enough.

Conditions for the two-inch option

Under §3-501.15(C), the method applies to cooked TCS food, requires regulatory approval, limits the food depth to two inches, requires the food to be held uncovered, and specifies a refrigeration unit that maintains an ambient air temperature of 41°F or less. The unit must have an electronic system that continuously monitors time and ambient air temperature.

The code excludes certain food cooled under other named provisions from this alternative. A manager should check §3-501.15(C) before applying the method to a special process such as cook-chill, sous vide, or time-as-control food. Do not assume every item can use the option because it fits a two-inch pan.

“Uncovered” creates a contamination risk if the food is exposed to dripping, splashing, overhead contamination, or items stored above it. The unit should be arranged so nothing can fall or drip onto the pan. The establishment needs an approved placement and access procedure, not just a shallow container.

Why shallow food cools faster

Heat must travel from the warm center of food through the mass and out to the surrounding air. Reducing depth shortens that travel distance and increases surface area relative to volume. A shallow layer can cool more quickly than a deep stockpot, especially when the refrigerator can move cold air around the container.

FDA added this option after considering evidence that uncovered foods at a depth of about two inches or less posed little risk of pathogen growth under the studied conditions. That finding supports an additional method; it does not mean every food, refrigerator, or loading pattern cools safely. The Code’s approval and continuous monitoring conditions remain.

How to run and verify it

Use a pan with a verified two-inch maximum food depth. Do not heap food into the middle or let a portion exceed the depth. Keep the pan uncovered only in the approved protected location. Maintain adequate spacing so cold air can reach containers; do not stack pans, crowd the unit, or block vents.

The continuous monitoring system tracks ambient air temperature and time. Staff still need to verify that the specific food is cooling on schedule using an appropriate probe and the establishment’s approved procedure. The sensor is not a substitute for food-temperature checks unless the approved plan and code authorize that monitoring approach.

Record batch identity, start time, food temperature checkpoints, refrigerator data, and corrective action. If the refrigeration unit rises above 41°F, the alarm fails, or a food sample misses a cooling limit, isolate the affected batch and follow the written corrective action. Do not assume the food can be rescued by putting it back into a cold unit.

Example

A kitchen cooks a shallow pan of rice for service. The health authority has approved the two-inch method, the food is spread at no more than that depth, and it is placed uncovered in a unit that stays at or below 41°F and continuously records time and air temperature. The cook measures the food’s warmest portion and documents the required cooling checkpoints.

If the same rice is piled five inches deep, stacked in a crowded walk-in, or placed in a unit without continuous monitoring, the conditions for this alternative are not met. The manager should use a different approved cooling method, such as dividing the batch into thinner portions or an ice bath.

The method is not a shortcut

The two-inch option does not replace proper cooling capacity, monitoring, protection from contamination, or staff training. Food establishment cooling and holding equipment must have sufficient capacity for the operation. Large pans should be split before they are placed in the refrigerator; the unit is not a safe way to cool an overloaded batch.

Local adoption can differ. FDA’s Food Code is a model, so a state or county may not yet permit the 2026 alternative or may require a specific approval process. Confirm adoption with the regulatory authority before changing procedures.

FAQs

Can any restaurant leave food uncovered to cool? No. The specific method requires regulatory approval and the code’s depth, refrigeration, and monitoring conditions.

Does two inches replace the two-stage cooling limits? No. The food must still meet the applicable time and temperature criteria.

Does a refrigerator display count as continuous monitoring? Not by itself; the provision calls for an electronic system that continuously monitors time and ambient air temperature.

Can the method be used for sous vide or cook-chill? Check the exceptions in §3-501.15(C); the alternative does not apply to certain separately regulated processes.

The evidence cited in the 2026 Annex concerns cooling shallow foods under studied conditions; it is not a universal scientific guarantee for every recipe. Thick sauces, dense foods, and deep containers can retain heat differently. Test the method with the actual food and equipment during an approved process, and do not infer safety from the top surface feeling cool.

The authority may require a written procedure showing pan dimensions, food depth, refrigerator capacity, monitoring, and corrective actions. Review refrigerator data for the full cooling period and inspect placement for overhead exposure. If the process is not approved or a required sensor is unavailable, use another cooling method allowed by the Code.
