What is the correct temperature for the surface of dishes in a machine dishwasher?

The correct temperature for the surface of dishes in a machine dishwasher is 160 degrees Fahrenheit. This temperature is essential for ensuring that the dishes are effectively sanitized during the wash cycle. At 160 degrees F, the heat is sufficient to kill harmful bacteria and pathogens that could be present on dishes, which is critical for food safety.

Additionally, maintaining this temperature ensures that detergent works effectively, enhancing cleaning and sanitation. The requirement of 160 degrees is specifically set to guarantee a consistent and safe level of sanitization for items that come in contact with food. While lower temperatures may clean surfaces, they do not adequately sanitize, posing a risk of foodborne illness. Therefore, it's important that commercial dishwashers are capable of reaching and maintaining this temperature for a set time period to ensure proper sanitation.
