Which type of thermometer is commonly used in food establishments?

Bimetallic stemmed thermometers are commonly used in food establishments because they provide accurate temperature readings essential for ensuring food safety. These thermometers feature a metal probe with a dial display that measures temperature; they are particularly useful for checking the internal temperature of larger food items such as roasts and casseroles. They work effectively in a range of food preparation scenarios, making them versatile tools in commercial kitchens.

In food safety, it is crucial to cook foods to the correct internal temperatures to eliminate harmful bacteria and prevent foodborne illnesses. Bimetallic stemmed thermometers typically have a thick probe that allows for accurate readings and are designed to measure temperatures from 0°F to 220°F, which covers the required range for various food products.

Other types of thermometers mentioned, such as digital kitchen timers, do not measure temperature and therefore cannot provide the necessary data for food safety. Infrared thermometers, while useful for surface temperature readings, may not provide the internal temperature necessary for proper cooking or reheating of foods. Mercury thermometers are largely being phased out due to safety concerns regarding mercury exposure, making them an unsuitable choice in food establishments.
