How often must thermometers be recalibrated?

Thermometers should be recalibrated at the beginning of every shift to ensure their accuracy and reliability in measuring temperatures. This practice is crucial in a food handling environment, as accurate temperature readings are essential for food safety. By recalibrating at the start of each shift, staff can verify that the thermometer maintains proper calibration, which helps prevent the risk of serving food that may be undercooked or improperly stored.

Frequent calibration checks at the beginning of each shift account for any potential shifts in accuracy that may occur due to factors like temperature fluctuations, physical impacts, or general wear and tear on the device. This ensures that food safety standards are consistently upheld throughout the entire period of operation.
