What temperature should the surface of utensils reach when using a mechanical dishwasher?

• A. 150°F
• B. 160°F
• C. 170°F
• D. 180°F

Answer: (B)

In a mechanical dishwasher, the surface of utensils needs to reach a temperature of 160°F to ensure that they are properly sanitized. This temperature is critical because it enables the effective removal of pathogens and harmful microorganisms, which is essential for food safety and health standards.

Using water at this temperature helps in the effective disinfection of utensils, as it assists in breaking down food residues and killing bacteria, viruses, and parasites that may be present on the surfaces. Additionally, many health and safety codes mandate that dishwashing processes must achieve this temperature as a standard practice to ensure public health is protected in food service operations.

While other temperatures listed may be effective for various wash cycles, 160°F stands out as the minimum required for sanitation, rather than just cleaning. Hence, reaching this temperature is essential in ensuring that dining and food preparation utensils are safe for use.
