What is the temperature requirement for hot water sanitizing in a warewash machine?

The correct temperature requirement for hot water sanitizing in a warewash machine is 180 °F. At this temperature, hot water sanitization is effective in killing harmful microorganisms that may be present on food contact surfaces, utensils, and equipment. The high temperature ensures that the heat penetrates surfaces adequately, achieving the necessary time and heat exposure to reduce or eliminate pathogens effectively.

Sanitizing at this temperature is crucial because it helps maintain food safety standards by ensuring that any potential contaminants are addressed before items are reused. Lower temperatures may not be sufficient to achieve the same level of sanitation, leading to an increased risk of foodborne illness if pathogens survive. Therefore, using water at 180 °F during the sanitizing cycle is essential to comply with safety regulations and best practices in food service environments.
