When should a thermometer be calibrated?

A thermometer should be calibrated to ensure accurate temperature readings, which are crucial for food safety and quality. Calibration is needed at various times, especially before and after shifts, to confirm it is functioning correctly when employees start their work, before deliveries to guarantee that transported items remain in safe temperature ranges, and after being dropped or experiencing significant temperature changes to ensure its accuracy has not been compromised. This comprehensive approach helps maintain safety standards by minimizing risks of foodborne illnesses that could occur due to incorrect temperature measurements. Regular calibration contributes to the consistency and reliability of cooking and storage temperatures throughout operations, thereby supporting adherence to health and safety regulations.
