How often should food thermometers be calibrated?

The best practice for calibrating food thermometers is to do so before the first use and periodically thereafter. This ensures that the thermometer provides accurate temperature readings, which are crucial in maintaining food safety. Calibration before the first use establishes a baseline for accuracy, while periodic checks help to confirm that the thermometer remains accurate over time, accounting for factors such as wear and tear or changes in the environment. Maintaining accurate temperature readings is essential to prevent foodborne illnesses by ensuring that food is cooked to the appropriate temperature and stored safely. This approach helps to ensure consistent food safety practices in any food handling or cooking environment.
