What is the primary function of penetration probes?

The primary function of penetration probes is to check the internal temperature of food. These probes are specifically designed to be inserted into the center of solid foods, such as meats, to accurately measure internal temperature. This is crucial in the food industry because ensuring that food reaches a safe internal temperature is vital for preventing foodborne illnesses.

By using penetration probes, food service professionals can confirm that foods are cooked to the necessary temperatures that kill harmful bacteria, ensuring food safety. This function is particularly important in maintaining compliance with health regulations and ensuring customer safety. The other choices, while related to different aspects of food safety and equipment monitoring, do not accurately reflect the primary use of penetration probes. For example, surface temperature measurements would require a different type of thermometer, such as an infrared thermometer, and humidity monitoring is conducted with hygrometers, not temperature probes. Checking color changes in meat is also an unreliable indicator of doneness and safety compared to temperature measurement.
