Which statement about Quats as a chemical sanitizer is NOT correct?

The statement regarding Quats needing a minimum water temperature of 68°F for 7 seconds of contact is not correct because while Quats (quaternary ammonium compounds) do require a certain contact time to be effective, the specifics about water temperature and contact duration can vary depending on the manufacturer’s recommendations. Standards for effective sanitization vary widely, and it's crucial to follow the guidelines provided by the manufacturer rather than a fixed temperature and time, as some manufacturers may specify different conditions.

In contrast, Quats are indeed known to be effective against a variety of microorganisms, including bacteria and some viruses, making them a popular choice for sanitization. They are also safe for use on food contact surfaces, provided they are used according to guidelines to ensure safety and efficacy. Always adhering to the manufacturer's recommended concentration ensures optimum effectiveness, as improper dilution can reduce sanitization performance.
