What temperature must food contact surfaces reach in a high temperature machine?

The correct temperature that food contact surfaces must reach in a high-temperature machine is 160°F. This temperature ensures that the surfaces are adequately sanitized to remove harmful pathogens that can cause foodborne illness. High-temperature dishwashing machines work by using hot water to not only clean but also to sanitize food contact surfaces effectively.

Reaching at least 160°F is critical because it allows for the proper denaturation of proteins in bacteria, viruses, and other microorganisms, rendering them inactive and safe. This temperature standard is in line with food safety regulations that are based on research regarding the thermal destruction of harmful microbes.

The other temperatures listed are below this critical threshold and, therefore, would not ensure proper sanitization of food contact surfaces. Maintaining the correct temperature is essential for food safety and preventing the spread of foodborne illnesses.
