The function of a food thermometer is to check the internal temperature of food. This is crucial for food safety as it ensures that food has reached a temperature sufficient to kill harmful bacteria that can cause foodborne illnesses. Different types of food require specific internal temperatures to be safely consumed; for instance, poultry should reach an internal temperature of 165°F to be considered safe. By using a food thermometer, food service workers can accurately determine whether food has been cooked properly, helping to prevent undercooked meals that could endanger health.

Other options such as measuring food weight, gauging freshness, and assessing cooking time do not directly relate to the primary purpose of a food thermometer. While cooking time may relate to temperature, it does not provide the immediate safety checks that measuring internal temperature offers. Therefore, understanding and correctly using a food thermometer is vital in the food service industry for ensuring the safety and quality of the food served.
