Why should thermometers used for monitoring be calibrated?

Calibrating thermometers used for monitoring is essential to ensure the accuracy of measurements. Accurate temperature readings are crucial in food safety, as they help prevent the growth of harmful bacteria and ensure that food is stored, cooked, and served at safe temperatures. If a thermometer is not calibrated, it may give erroneous readings that could lead to improper food handling or preparation, putting food safety at risk.

While there are other important factors in thermometer usage, such as reducing monitoring time or ensuring compliance with regulations, the primary focus for calibration remains on achieving precise and reliable temperature readings. Calibration helps to correct any deviations that may occur due to factors like regular use or environmental influences, thereby ensuring consistent and valid data for food safety practices.
