How often should refrigerator temperatures be checked?

The best practice for checking refrigerator temperatures is at least once a day. Maintaining appropriate temperatures is crucial for food safety, as it helps to inhibit the growth of harmful bacteria. The USDA recommends that refrigerators should be kept at 40°F (4°C) or below to ensure that food remains safe for consumption. Daily monitoring allows food handlers to quickly identify any temperature fluctuations that could compromise food safety, especially if the refrigerator malfunctions or if there is a power outage. Regular checks help ensure that food is stored at safe temperatures, thus protecting public health and preventing foodborne illnesses.
