What type of thermometer is specified for checking temperatures?

• A. Calibrated and sanitized stem thermometer
• B. Disposable plastic thermometer
• C. Dial kitchen thermometer without calibration
• D. Instant digital thermometer without calibration

Answer: (A)

Accurate, safe temperatures come from using a tool that you can sanitize between uses and that you know reads correctly. A calibrated and sanitized stem thermometer fits that requirement. The stem design lets you insert the probe into the thickest part of foods to get an accurate internal reading, and the stem can be cleaned and sanitized after each use to prevent cross-contamination. Calibration ensures the reading matches the actual temperature, so you’re not relying on a drifted or wrong value.

Other options fall short in different ways: disposable plastic thermometers aren’t designed for repeated use or reliable accuracy, a dial kitchen thermometer that hasn’t been calibrated can drift and misreport temperature, and an instant digital thermometer would also need calibration and proper sanitation to be trusted. The combination of being both calibrated and sanitized makes the stem thermometer the standard for checking temperatures.
