Why is a properly calibrated thermometer important in food safety?

A properly calibrated thermometer is essential in food safety because it provides accurate readings that are critical for ensuring that foods are cooked and stored at safe temperatures. When food is not cooked or stored at the correct temperatures, there is a significant risk of foodborne illnesses. Accurate temperature measurements help determine whether food has reached the necessary internal temperature to kill harmful bacteria and whether it is kept out of the temperature danger zone where bacteria can rapidly multiply.

By relying on a calibrated thermometer, food handlers can verify that meat, poultry, and other potentially hazardous foods are cooked thoroughly and held at safe temperatures, thereby reducing the risk of foodborne pathogens and ensuring the safety of the food being served. Proper calibration ensures that the thermometer's readings are reliable, which is vital for adherence to food safety standards and regulations.
