How often should thermometers be calibrated food safety?

@alf.kerluke 

Thermometers used for food safety should be calibrated at least once a year or whenever they are dropped or subjected to extreme temperature fluctuations. Additionally, calibration should be performed before and after use if the thermometer is used for critical measurements or in critical food areas to ensure accurate readings.

It is important to note that this frequency might vary depending on the specific guidelines and regulations of the local health department or food safety organization. It is recommended to consult these guidelines to ensure compliance with the appropriate calibration schedule.
