What Is the 2026 FDA Food Code’s Two-Inch Cooling Method?

The 2026 FDA Food Code adds food at a depth of no more than two inches as a model cooling method for time/temperature control for safety (TCS) food. That does not mean every US establishment can replace food-temperature checks with a two-inch pan. The model contains two different routes: the normal cooling method in section 3-501.15(A)(7), and a separate approval-based alternative in section 3-501.15(C).

TapTick can help teams schedule cooling checks, capture readings and corrective actions, and give managers visibility across locations. See the TapTick features.

What changed in the 2026 Food Code?

FDA published the 2026 Food Code on September 17, 2026. Its summary of changes identifies two additions to model section 3-501.15:

• new subparagraph 3-501.15(A)(7), which lists placing food at a depth of no more than two inches as an additional cooling method; and
• new paragraph 3-501.15(C), which creates a separate cooling option based on approval, a maximum food depth of two inches, uncovered food and continuous electronic monitoring of refrigerator time and ambient air temperature.

These additions address method and verification. They do not make deep containers safe, turn ordinary cold-holding equipment into unlimited cooling capacity, or make the 2026 text immediately enforceable in every jurisdiction.

The model retains the familiar cooling limits in section 3-501.14. Cooked TCS food following the normal route must cool from 135°F to 70°F within two hours and from 135°F to 41°F or less within six hours total. TCS food prepared from ingredients at room temperature, such as reconstituted food or canned tuna, must cool to 41°F or less within four hours.

What are the two cooling routes?

The distinction matters because both routes mention two inches, but they do not have the same conditions.

Route 1: use two inches as a normal cooling method

Model section 3-501.15(A)(7) treats food depth of no more than two inches as one available method. It sits alongside shallow pans, smaller portions, rapid cooling equipment, an ice-water bath, heat-transfer containers, adding ice as an ingredient and other effective methods.

Under this route, the food must still meet the section 3-501.14 food-temperature limits. Two inches describes the maximum depth, not proof that cooling succeeded. Check the food temperature at the required points and take corrective action if the limit is missed.

Route 2: use the separately approved alternative

Model section 3-501.15(C) creates an alternative for cooked TCS food that, if approved by the regulatory authority:

• is filled no more than two inches deep;
• is held uncovered; and
• is held in a refrigerator that maintains an ambient air temperature of 41°F or less and continuously monitors time and ambient air temperature electronically.

FDA explains in Annex 3 that this route excludes direct food-product temperatures and relies on the continuous ambient record. Approval must come from the regulatory authority that issued the establishment’s permit. An operator should not adopt this route merely because suitable pans and a temperature logger are available.

How does the normal two-inch method work?

Start by defining the food, batch size, container and refrigeration equipment. “Two inches” means the depth of the food, not the nominal height of the pan. A six-inch pan with only two inches of food may meet the depth element; a two-inch pan overfilled above its rim does not.

Arrange containers so cold air can circulate and heat can transfer through their walls. Under model section 3-501.15(B), cooling containers should be loosely covered, or uncovered when protected from overhead contamination, during cooling. Do not stack hot pans tightly or crowd a refrigerator beyond the capacity needed to remove heat.

Use one or more methods when necessary. A thick food such as chili, gravy, rice or refried beans may need smaller batches, an ice bath, stirring, ice as an ingredient or rapid cooling equipment as well as a two-inch depth. FDA’s public-health explanation says not every TCS food will cool sufficiently using the new method and places responsibility on the person in charge or permit holder to demonstrate effectiveness.

Measure the food in the slowest-cooling part of the batch with a suitable, accurate thermometer. Record the start temperature and time, the two-hour checkpoint and the final temperature and time. TapTick’s related guide explains what a food cooling log should record.

When can ambient monitoring replace food readings?

Only consider the paragraph (C) route after confirming that the applicable regulatory authority has adopted a provision that permits it and has approved its use for the establishment. The 2026 model excludes this alternative for food cooled under the model’s provisions for non-continuous cooking, certain reduced-oxygen packaging processes and time as a public health control.

The model requires a refrigeration unit that stays at 41°F or less and electronically monitors both time and ambient air temperature continuously. A dial checked twice per day, a handwritten refrigerator log or a device that records only occasional readings does not match that model description.

Approval should be specific enough that managers know:

• which establishment, refrigeration unit, foods and container sizes are covered;
• the maximum two-inch food depth and requirement to hold the food uncovered;
• the continuous-monitoring device, its placement, accuracy checks and record retention;
• the alarm or review limits and who responds;
• what happens if the refrigerator exceeds 41°F, monitoring stops or food is loaded incorrectly; and
• when the authority’s approval must be reviewed or renewed.

Do not describe this as “no temperature monitoring.” It replaces direct product-temperature verification with an approved, continuously monitored ambient process under defined conditions.

What should an approval request demonstrate?

Annex 3 says the person in charge or permit holder and the regulatory authority should discuss whether the alternative facilitates cooling of the specified TCS food. FDA identifies factors including equipment capacity, the continuous electronic system, the person in charge’s cooling knowledge, data showing the selected foods will cool, written standard operating procedures, employee training and relevant outbreak hazards.

A practical submission may therefore include:

• the food list and maximum batch size;
• pan dimensions and maximum fill depth;
• the refrigeration unit’s usable capacity and loading layout;
• validation runs showing performance for the hardest-to-cool products and normal worst-case loads;
• continuous-monitor specifications, sensor location and accuracy-check process;
• the proposed SOP and staff training plan;
• records, review frequency and retention period; and
• corrective actions for temperature excursions, power loss, device failure and procedure error.

Ask the authority what evidence it expects before preparing the submission. Approval processes and terminology may differ by state or locality.

What should the cooling procedure say?

A usable cooling procedure should let a shift employee perform the process without guessing. For each covered food, specify:

1. the batch size and preparation point at which cooling begins;
2. the container type, maximum two-inch depth and whether other methods are required;
3. the refrigerator or rapid-cooling equipment to use and how pans are arranged;
4. whether the normal food-temperature route or an approved ambient-monitoring route applies;
5. the readings, times, checks or continuous records required;
6. how the food is protected from contamination while loosely covered or uncovered;
7. the pass limits and the exact corrective-action decision points;
8. who verifies completion and when the food may be covered, labeled and moved to storage; and
9. what record is kept and who reviews exceptions.

A company-wide instruction that says only “use shallow pans” is not enough. Employees need a measurable depth, named equipment and a decision path when cooling is off track.

What should operators record?

For the normal route, the record should connect the product-temperature evidence to the actual batch. Include the food, batch or preparation identifier, quantity, pan depth, method, start time and temperature, checkpoint readings, final reading, employee, equipment and corrective action.

For an approved ambient route, retain the continuous electronic time-and-air-temperature record in the form required by the authority, together with the food, batch, pan depth, refrigeration unit, loading time, employee, review result and any alarm or deviation response. Keep the written approval and current SOP accessible to the person in charge.

The 2026 Food Code does not create one universal cooling-log form or retention period for every US establishment. The adopted jurisdictional code, permit conditions, approval and company procedure control what is required. Record enough to show that the correct route was followed and that exceptions were resolved.

What if food misses a cooling limit?

Do not simply restart the clock, edit the start time or move a failed batch into a different pan and mark it complete. Isolate the affected food and follow the adopted code and site corrective-action procedure. The safe decision may depend on the temperatures reached, elapsed time, food type and regulator-approved process.

A useful escalation rule tells employees when to notify the person in charge, what information to preserve, whether an authorized rapid reheating and recooling process is permitted, and when the food must be discarded. If the failure involves an approved alternative process, also preserve the continuous data and notify the regulatory authority when the approval or local rule requires it.

Review the cause, not only the batch. Common causes include excess depth, oversized batches, blocked airflow, tightly covered hot food, overloaded refrigeration, warm equipment, delayed checks, inaccurate thermometers and missing staff training.

How should multi-site operators roll this out?

Do not switch every location to the 2026 wording at once. Start with a jurisdiction register that identifies the retail code edition, local amendments, effective date, regulator and permit conditions for each site.

Where the normal two-inch method is available, validate it against the foods and equipment used at that site. Where the alternative ambient route is being considered, obtain approval separately as required; an approval for one establishment or one refrigerator should not be assumed to cover every site.

Use a controlled rollout:

• map the rule and approval status by location;
• select foods and equipment suitable for the method;
• validate the hardest-to-cool normal load;
• issue a clear SOP and train each shift;
• deploy the correct check or monitoring workflow only to approved sites;
• review missed limits, incomplete records and device gaps centrally; and
• revalidate after recipe, batch-size, container, equipment or loading changes.

Which rule applies at my location?

FDA’s Food Code is a model offered to state, local, tribal, territorial and federal regulators. It is not automatically effective nationwide. A jurisdiction may still use an earlier edition, adopt the 2026 text later, amend it or impose different approval and recordkeeping conditions.

Confirm the code with the authority that licenses or inspects the establishment. Ask which Food Code edition and amendments are in force, whether section 3-501.15(A)(7) is available, whether the paragraph (C) alternative has been adopted, what approval is required and when any change takes effect.

This article addresses retail and foodservice establishments. A manufacturer, central facility or federally inspected meat or poultry operation may be subject to FSMA regulations, USDA FSIS requirements or other controls. Do not substitute the retail Food Code process for the regulatory framework that applies to those activities.
