How often should food temperatures be monitored in a refrigerator?

  1. Hourly

  2. Twice a day

  3. Once a week

  4. Daily

The correct answer is: Hourly

Food temperatures should be monitored in a refrigerator hourly to ensure that food is being held at safe temperatures. This frequent monitoring helps identify any potential issues with temperature control promptly, allowing for corrective actions to be taken to prevent foodborne illness. Monitoring temperatures only once a week, twice a day, or daily may not catch temperature fluctuations that could compromise the safety of the food stored in the refrigerator.
