What temperature must a high-temperature dishwasher's final sanitizing rinse be?

1. 170 F

2. 180 F

3. 160 F

4. 150 F

The correct answer is: 180 F

A high-temperature dishwasher's final sanitizing rinse must reach a temperature of at least 180 degrees Fahrenheit to effectively sanitize dishes and utensils. This high temperature ensures that any harmful bacteria, viruses, or other pathogens present on the surfaces are eliminated during the rinse cycle. The capability of the dishwasher to reach and maintain this temperature is crucial for food safety, as lower temperatures may not be sufficient to achieve the necessary level of sanitation. For instance, while 170 degrees Fahrenheit is close, it typically does not provide the same assurance of sanitization as 180 degrees. Achieving the correct temperature is essential for compliance with health regulations and for ensuring the safety of food served to customers.
