What should you do if a thermometer shows an incorrect reading?

When a thermometer shows an incorrect reading, calibrating or replacing the thermometer is the appropriate action to take. Calibration ensures that the thermometer is providing accurate measurements, which is crucial for food safety. An inaccurate thermometer could lead to improper cooking temperatures, risking the safety of the food being prepared and served. Regular calibration helps maintain the reliability of temperature readings, particularly in environments like kitchens where temperature-sensitive foods are handled.

Replacing the thermometer may be necessary if it cannot be effectively calibrated or is unreliable even after adjustments. By ensuring that the thermometer is functioning correctly, food handlers can maintain proper food safety standards, minimizing the risk of foodborne illnesses.

It's essential not to adjust the temperature of the food based solely on an incorrect reading since that could lead to serving food that is undercooked or improperly stored. Using a faulty thermometer without changes compromises food safety, and prematurely discarding a thermometer can be wasteful if it can be calibrated correctly. Thus, calibration or replacement is the best course of action when faced with an inaccurate thermometer.
