What must be done if a thermometer is found to be outside of calibration?

When a thermometer is found to be outside of calibration, it is vital to calibrate it before use. Calibration ensures that the thermometer provides accurate temperature readings, which is essential for food safety. Accurate temperature measurements are crucial for preventing foodborne illnesses, ensuring foods are cooked to safe temperatures, and helping to maintain proper storage conditions.

If a thermometer is not properly calibrated, it may give misleading readings. This could lead to undercooking or overcooking food, which can pose health risks, particularly with raw meats or dairy products that need to be maintained at specific temperatures. Thus, rather than replacing the thermometer or disposing of it, calibrating it allows it to continue being a reliable tool in food handling practices.
