How frequently should food thermometers be calibrated?

Food thermometers should be calibrated once a month to ensure they provide accurate temperature readings. This frequency is important because regular calibration helps account for any potential inaccuracies that may develop over time due to factors like use, temperature fluctuations, or physical impacts. Regular calibration is essential for food safety, especially in environments where precise temperature control is necessary to prevent foodborne illnesses. Monthly calibration allows for timely adjustments to guarantee that the thermometer remains reliable and effective for ensuring food is cooked and stored at safe temperatures.
