Checking the Quat concentration is crucial to ensure proper sanitation because Quaternary Ammonium Compounds (Quat) are widely used as sanitizers to kill bacteria and other pathogens on surfaces. Maintaining the correct concentration is vital for achieving the desired disinfecting effect. If the concentration is too low, it may not effectively eliminate harmful microorganisms, compromising health and safety standards. Conversely, if the concentration is too high, it could pose risks to both employees and customers, potentially damaging surfaces and creating toxic environments.

While maintaining staff efficiency, reducing cleaning time, and keeping costs low are all important factors in a restaurant's operational strategy, they are secondary to the primary responsibility of ensuring that all areas are sanitized effectively to meet health regulations. Proper sanitation protects customers from foodborne illnesses and ensures compliance with health codes, making it the top priority.
