The type of thermometer that should never be used in food safety is glass or mercury-filled thermometers. These thermometers pose a significant risk if they break, as the mercury can contaminate food and the environment. Mercury is a toxic substance that can lead to serious health issues if ingested, inhaled, or if it enters the body through skin contact.

In contrast, bi-metallic and digital thermometers are designed to withstand kitchen environments and provide accurate temperature readings essential for food safety. Infrared thermometers, while useful for measuring surface temperatures from a distance, do not require direct contact with the food and are safe for use when applied correctly.

Using glass or mercury-filled thermometers can not only compromise food safety due to the risk of contamination but also violate health regulations concerning food equipment. Therefore, it's crucial to utilize thermometers that are safe, reliable, and suitable for food environments to ensure proper monitoring of food temperatures.
