How often should food thermometers be calibrated?

Food thermometers should be calibrated before each use and periodically throughout the day to ensure accuracy in measuring temperatures. This practice is crucial in food safety to prevent foodborne illnesses, as incorrect temperature readings can lead to improper cooking or storage of food, potentially allowing harmful pathogens to survive.

Calibrating a thermometer before each use ensures that it is reading accurately for that specific instance, which is particularly important when dealing with different types of food that require specific cooking temperatures. Periodic calibration throughout the day accounts for any minor shifts in accuracy that could occur with changes in temperature extremes or due to frequent handling of the device.

This level of diligence is necessary to maintain compliance with health standards and to guarantee that food is prepared and served at safe temperatures. Regular calibration fosters confidence in the thermometer's readings, helping food managers ensure that all safety measures are being adhered to effectively.
