Why is thermometer calibration important and how often should it be checked?

• A. To ensure accuracy; check during setup and periodically (daily or weekly)
• B. To save energy; check monthly
• C. To improve flavor; check before each meal
• D. To prevent spoilage; check yearly

Answer: (A)

Maintaining accurate temperature readings is essential because food safety and quality depend on knowing the real temperatures during cooking, cooling, and holding. If a thermometer drifts, you might undercook meat, fail to hold foods safely, or misjudge doneness. Regular calibration keeps the instrument trustworthy. It should be calibrated when you first use it or after it’s been dropped or exposed to extreme temperatures, and then checked on a routine basis—typically daily or weekly in a busy kitchen—so drift can be caught early. This practice keeps accuracy and control at the forefront, rather than focusing on energy use or flavor alone.
