Government-backed temperature guidance
What Temperature Should a Refrigerator Be?
The short answer
A refrigerator should maintain 40°F (4°C) or below. Use an appliance thermometer rather than relying only on the control dial.
Decision table
| Situation | Limit or action | What it means |
|---|---|---|
| Safe refrigerator maximum | 40°F (4°C) | FoodSafety.gov |
| Above 40°F for over 2 hours | Discard affected perishables | Evaluate item by item |
| Where to measure | Warmest practical area | Allow the reading to stabilize |
| Freezer compartment | 0°F (-18°C) | Use a separate thermometer |
How to apply the rule
Use an appliance or food thermometer to verify the temperature. Control dials, food color, smell, and touch are not substitutes for a measured reading.
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
- Identify the exact food, package state, and whether it is raw or cooked.
- Record the thawing method, storage temperature, and elapsed time that actually apply.
- Use the strictest applicable row in the table.
- Do not taste food to determine safety after excessive warm exposure.
