Food Safety Temperatures: A Cold Storage Guide (FDA/HACCP)
The temperature targets and monitoring habits that keep cold inventory safe and compliant.
Keeping food safe in cold storage comes down to holding the right temperature consistently and staying out of the "danger zone." This guide summarizes widely used FDA/HACCP-aligned targets — always follow your local code and your own HACCP plan.
The temperature danger zone
Bacteria multiply fastest between 40°F and 140°F. Perishable food held in that range for more than 2 hours (1 hour above 90°F) should generally be discarded — relevant during power outages and equipment failures.
Cold storage temperature targets
| Storage | Target temperature |
|---|---|
| Refrigerator / cooler | 40°F or below (ideal 34–38°F) |
| Freezer | 0°F or below |
| Meat & poultry | 28–32°F |
| Produce & dairy | 34–40°F |
| Frozen goods / ice cream | -10°F to 0°F |
Monitoring & compliance
- Use a calibrated thermometer and log temperatures regularly.
- For pharma or regulated product, use continuous monitoring (pharma cold chain).
- When renting, confirm the unit holds your target range and has reliable monitoring.
Frequently Asked Questions
What is the temperature danger zone for food?
The danger zone is 40°F to 140°F, where bacteria grow fastest. Discard perishable food held in that range for more than 2 hours (1 hour above 90°F).
What temperature should a refrigerated trailer hold for food?
Keep refrigerated food at 40°F or below (ideally 34–38°F) and frozen food at 0°F or below. Match the unit’s set point to your specific product and monitor it continuously.
