How often should food thermometers be calibrated?

Food thermometers play a crucial role in ensuring that food is cooked to safe temperatures, thereby preventing foodborne illnesses. Calibrating thermometers regularly ensures that they provide accurate readings. The recommended frequency is at least once a day or after any significant temperature changes, such as when thermometers are used in a different environment or dropped.

Daily calibration checks help to ensure that the readings are consistent and reliable, particularly in a busy kitchen setting where temperature fluctuations can occur frequently. By doing this, food handlers can maintain food safety standards and provide customers with properly cooked and safe food.

While calibrating once a week or monthly may seem sufficient, it does not account for everyday variations in temperature that can affect thermometer accuracy. Similarly, relying on the condition of the thermometer, such as only calibrating when it appears broken, could lead to significant risks if inaccuracies go unnoticed. Regular calibration is essential in maintaining food safety and quality.
