How often should thermometers be calibrated?

Thermometers should be calibrated every day to ensure that they provide accurate readings. Accuracy is essential in maintaining food safety, especially in the produce department where temperature control is vital. Daily calibration helps detect any drift in the thermometer's accuracy that may occur due to factors like wear and tear or exposure to extreme temperatures. By calibrating each day, you guarantee that you are using the most reliable information to manage temperature-sensitive products effectively, which is essential to prevent spoilage and maintain quality.

Other options suggest less frequent calibration, which may lead to inaccuracies over time, potentially compromising food safety and quality standards in the produce department.
