Food Safe Temperatures and Cooling Limits Chart (F and C)

When a floor supervisor needs to know the cooling limit or the hot hold minimum, they should not have to open a PDF of the full Food Code. This chart puts the common limits in one searchable table with both Fahrenheit and Celsius.

Limits shown are widely published FDA Food Code and USDA values for planning. Your HACCP plan critical limits must be validated for your own product and process, and your regulator or customer may require stricter values.

How to use the chart

Filter by process step to see every limit at cooking, holding, cooling, reheating or receiving. Use it to write critical limits into a HACCP plan, to set alarms on a blast chiller or hot box, and to train new line staff. Export the rows you need to Excel or PDF and attach them to the relevant monitoring log, so the number on the log matches the number in the plan.

Always record the probe reading, not the equipment set point
Calibrate thermometers against an ice point and boiling point on a schedule
Write the time with the temperature, because time is half of every limit

Two-stage cooling explained

The Food Code cooling rule has two clocks. Cooked food must fall from 135 F to 70 F within two hours, and from 70 F to 41 F within four more, for six hours total. The first stage matters most because the 70 to 125 F zone supports the fastest growth of spore formers such as Clostridium perfringens. If the first stage is missed, the food should be reheated to 165 F and cooled again or discarded according to your procedure.

Regulatory limit versus validated limit

These numbers are baselines. For processes such as cook-chill, sous vide or large-mass products, a validated lethality study or a regulator-approved variance may justify different parameters. Retail rules in the Food Code and processing rules for plants under 21 CFR 117 or USDA FSIS differ, so confirm which authority and which customer standard apply to you.

Common mistakes

Measuring surface temperature instead of the thickest part, cooling food in deep full pans, stacking containers in a blast chiller, ignoring the receiving check on frozen goods, and keeping logs that record only passes. A log with no corrective action entries across a year is more often a sign of weak monitoring than of perfect control.

Frequently Asked Questions

What is the temperature danger zone?

In the FDA Food Code it is 41 F to 135 F (5 C to 57 C), the range where pathogens grow fastest in time and temperature control for safety foods. Food should spend as little time there as possible.

How fast must cooked food be cooled?

From 135 F to 70 F within two hours, then from 70 F to 41 F within four additional hours. That is six hours total, and the first two hours are the hard limit.

Is 160 F or 165 F correct for ground meat?

FDA Food Code lists 155 F for 17 seconds for ground meat in retail settings, and USDA consumer guidance is 160 F. Poultry is 165 F. Plants should use the validated critical limit in their own HACCP plan.

Do these limits apply to a manufacturing plant?

They are a common baseline, but plants follow 21 CFR 117 or USDA rules and their validated process. Use the chart for reference and confirm limits against your own process authority and validation study.
