How often should food thermometers be calibrated?

Food thermometers are essential tools in ensuring that foods are cooked to safe temperatures, which helps to prevent foodborne illnesses. Calibration is necessary to ensure that the thermometer provides accurate readings, which is crucial when assessing whether food has reached a temperature that is safe for consumption.

Choosing to calibrate thermometers before each use or at least once a day is considered best practice because temperature readings can be affected by various factors, such as improper handling, exposure to extreme temperatures, or physical damage. By calibrating before each use, especially in a busy kitchen environment, you ensure that the thermometer's reading is reliable, allowing for proper cooking and food safety management.

The emphasis on daily calibration ensures that any potential drift that may occur over time due to wear or use is corrected, leading to more precise readings that are crucial for food safety. This practice fosters a higher standard of care in food handling and preparation, ultimately contributing to public health and safety.
