At what surface temperature must food contact surfaces be maintained in a high-temperature dish machine?

The correct surface temperature for food contact surfaces in a high-temperature dish machine needs to be maintained at 180°F. This temperature is crucial because it ensures that surfaces become sanitized effectively, killing harmful pathogens and bacteria that could lead to foodborne illnesses. High-temperature dish machines work by using water at this elevated temperature to not only wash dishes but also to serve as the final sanitizing step, which is essential for both food safety and compliance with health regulations.

Maintaining surfaces at or above this temperature ensures that they reach the necessary thermal energy required for effective sanitation. If the temperature is lower than this threshold, the sanitization process could be compromised, increasing the risk of cross-contamination and foodborne illness outbreaks. This standard is in line with health codes and guidelines that govern safe food handling practices.
