State Food Safety Practice Exam

How often should most thermometers, except for bimetallic, be calibrated?

1. Once a week

2. Every four hours

3. After each time it is used

4. As often as needed according to the manufacturer's instructions

The correct answer is: As often as needed according to the manufacturer's instructions

Most thermometers, except for bimetallic types, should be calibrated as often as needed according to the manufacturer's instructions to ensure precision and accuracy. Calibration is critical for maintaining the integrity of temperature readings in food safety practices, as improper readings can lead to unsafe food handling and potential health risks. Each manufacturer may have specific guidelines based on the design and use of the thermometer, which dictate how frequently calibration is necessary to maintain optimal performance. Regular calibration not only enhances food safety practices but also helps in compliance with health standards and regulations.
