The ideal temperature for your refrigerator should be between 34°F and 38°F (1°C to 3°C) to keep food fresh and safe. This range slows bacterial growth without freezing your food
. The U.S. Food and Drug Administration (FDA) recommends keeping the fridge temperature at or below 40°F (4°C)
. Setting the temperature closer to 37°F (3°C) is often considered optimal for food safety and freshness
. Temperatures above 40°F (4°C) can increase the risk of bacterial growth, while temperatures below about 34°F (1°C) may cause unwanted freezing of some foods
. If your fridge has a numbered dial (usually 1 to 5), a higher number means colder. Start by setting it to the coldest setting (5) and then adjust downward as needed after checking the actual temperature with a thermometer, since dial numbers vary by model
. In summary:
- Recommended fridge temperature: 34°F to 38°F (1°C to 3°C)
- Maximum safe temperature: 40°F (4°C)
- Avoid temperatures above 40°F or below 34°F to prevent spoilage or freezing
- Use a thermometer to verify actual fridge temperature after adjustments
This ensures your food stays fresh longer and reduces the risk of foodborne illness
