HACCP Critical Limit Calculator
Evaluate time/temperature critical limits for different food types per FDA Food Code.
Inputs
Results
Critical Limit Met
No
Danger Zone Exceeded
No
How to Use This Calculator
- Select the food type being cooked (poultry, ground meat, whole muscle, seafood, or reheated food).
- Enter the measured internal temperature in °F and hold time in seconds.
- Enter cumulative danger zone time (minutes food spent between 40–140 °F).
- The calculator shows whether the critical limit is met, required temperature and hold time, any deficiencies, danger zone status, and estimated log reduction achieved.
- If critical limit is not met, continue cooking until both temperature and hold time requirements are satisfied.
What each input means
- Food Type
- Select the food type
- Internal Temperature (°F)
- Measured internal temperature of the food.
- Hold Time at Temp (seconds)
- Time held at the measured temperature.
- Danger Zone Time (minutes)
- Cumulative time food spent between 40-140°F.
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersFood Type = 2, Internal Temperature (°F) = 160, Hold Time at Temp (seconds) = 15, Danger Zone Time (minutes) = 30 = 4 input(s) provided
