What is the purpose of penetration probes?

Penetration probes are specifically designed to measure the internal temperature of food items, particularly those that are thick or dense. This capability is critical for ensuring food safety, as it allows for accurate temperature readings that determine whether food has been cooked to the appropriate temperature to eliminate harmful pathogens. Using a penetration probe enables food handlers to insert the probe into the center of meats or casseroles, providing a clear indication of whether the internal temperature is suitable for safe consumption.

The other options refer to different types of temperature measurements. For example, checking the temperature of liquids typically requires immersion probes, while surface probes are used to gauge the temperature of griddles or countertops. Monitoring food storage conditions involves examining the temperature within coolers or freezers, which can utilize various thermometer types but not specifically penetration probes.
