How often should food thermometers be calibrated?

Food thermometers should be calibrated before each use and regularly to ensure their accuracy. Calibration is essential because even a small discrepancy in temperature readings can lead to unsafe food-handling practices, potentially resulting in foodborne illnesses.

Regular calibration helps to account for any wear and tear or exposure to extreme temperatures that the thermometer may have experienced over time. Additionally, it ensures that any thermometer used is providing the most accurate readings possible, which is crucial when preparing food that requires precise temperature control for safety reasons. Following this practice supports food safety standards and promotes the health of consumers.
