How often should food thermometers be calibrated?

Food thermometers should be calibrated before each use or regularly, as recommended, to ensure accurate readings and reliable food safety practices. Calibration is essential because even slight inaccuracies can lead to undercooked or overcooked food, which poses a risk for foodborne illnesses. Factors such as temperature fluctuations, wear over time, or improper handling can affect a thermometer's accuracy.

Having a procedure in place to check the calibration regularly helps maintain the integrity of temperature measurements, which is especially critical in cooking, cooling, and storing food. Regular calibration supports compliance with food safety guidelines, ensuring that food is cooked and held at safe temperatures to prevent the growth of harmful bacteria. This practice aligns with best practices in food safety management and serves to protect public health.
