How to apply the rule

The clock is cumulative while perishable food is between 40°F and 140°F. Putting food back in the refrigerator does not erase earlier warm exposure.

The package instructions control when they are stricter. If the time, temperature, or handling history is unknown, the page cannot prove the food is safe; choose the conservative action.

Practical steps

  1. Identify the exact food, package state, and whether it is raw or cooked.
  2. Record the thawing method, storage temperature, and elapsed time that actually apply.
  3. Use the strictest applicable row in the table.
  4. Do not taste food to determine safety after excessive warm exposure.
