Food thermometers should be calibrated before each use to ensure accurate readings when measuring the temperature of food. Calibration is crucial as it confirms the thermometer's precision and reliability, which directly impacts food safety. Accurate temperature readings are essential to prevent foodborne illnesses, as they help ensure that food is cooked to the proper temperature and stored safely. By calibrating the thermometer before each use, food handlers can adjust for any shifts in accuracy, especially after being dropped or exposed to extreme temperatures.

Regular calibration helps maintain hygiene and safety standards in food preparation and service, reinforcing the importance of using properly functioning equipment in a food handling environment. In contrast, the other options suggest less frequent checks, which may lead to undetected inaccuracies and potential food safety risks.
