What is the minimum temperature for using QUAT as a chemical sanitizer?

The minimum temperature for using QUAT (quaternary ammonium compounds) as a chemical sanitizer is 75°F. This temperature is essential because QUATs require a certain thermal activation to function effectively as sanitizers. At temperatures below the recommended level, the efficacy of the chemical may be compromised, resulting in insufficient disinfection of surfaces and equipment in food service settings. Ensuring that the solution is at least 75°F allows for optimal biocidal action, helping to destroy harmful microorganisms and maintain food safety standards. Proper adherence to this guideline is crucial in preventing foodborne illnesses and ensuring public health in food, lodging, and institutional settings.
