How often should a refrigerator be checked for temperature to ensure food safety?

Checking the refrigerator temperature at least once a day is critical for maintaining food safety. It's essential for preventing foodborne illnesses that can arise from food being stored at unsafe temperatures. The USDA recommends keeping refrigerator temperatures at or below 40°F (4°C) to inhibit the growth of harmful bacteria.

Daily checks ensure that any fluctuation in temperature is detected and addressed promptly, helping to prevent spoilage and food safety hazards. This frequency also allows for immediate action if the temperature rises above safe levels, whether due to a malfunction or a door being left ajar. Regular monitoring contributes significantly to food safety in both commercial and home environments, promoting awareness and proactive measures in food storage practices.
