How often should food thermometers be calibrated?

Calibrating food thermometers regularly, and especially before each use, is vital to ensure accurate temperature readings. Thermometers can be affected by factors such as temperature fluctuations, accidental drops, or prolonged exposure to extreme conditions, leading to inaccuracies. By checking the calibration frequently, food safety professionals can ensure that they are getting reliable data, which is crucial for cooking food to safe temperatures and thus preventing foodborne illnesses. This practice aligns with food safety standards that prioritize maintaining equipment in proper working order, facilitating effective monitoring of food safety conditions. Regular calibration practices help in maintaining the integrity of temperature-sensitive food handling processes.
