What is the minimum required temperature for a high-temp dishwasher's final sanitizing rinse?

The minimum required temperature for a high-temp dishwasher's final sanitizing rinse is 180°F (82°C). This temperature is crucial because it ensures that the sanitization process effectively eliminates harmful bacteria and pathogens from the dishes and utensils. Proper sanitization is a key component of food safety, helping to prevent foodborne illnesses.

High-temperature dishwashers work by using the heat from hot water to achieve sanitation, rather than relying on chemicals. When the water reaches at least 180°F during the final rinse cycle, it helps to ensure that surfaces of dishware are adequately sanitized. Maintaining this temperature is critical for the dishwasher to perform effectively and to comply with health and safety regulations regarding food service operations.

Other temperature options listed are insufficient for achieving the necessary level of sanitation, which is why they do not meet the requirement for a high-temperature rinse in a commercial dishwasher setting.
