What is the minimum utensil surface temperature required during mechanical sanitization of food service equipment?

• A. 140 degrees F
• B. 180 degrees F
• C. 200 degrees F
• D. 160 degrees F (71 deg C)

Answer: (D)

Heat sanitization relies on elevating the utensil surface to a level that rapidly inactivates microorganisms during the cleaning cycle. The minimum utensil surface temperature for this process is 160°F (71°C). At this temperature, common foodborne pathogens are killed quickly given the proper contact time, making the utensils safe for use after mechanical sanitizing. While some dishwashing systems push the water to higher temperatures (such as a final rinse around 180°F), 160°F is the lowest surface temperature that still achieves effective sanitization in typical mechanical cycles. Temperatures below this threshold don’t reliably eliminate pathogens within the required time.
