What is the acceptable range of parts per million (PPM) for sanitizer solution?

The acceptable range of parts per million (PPM) for a sanitizer solution is crucial for ensuring effective sanitation while maintaining safety for food contact surfaces. A concentration of 150-200 ppm is recognized as effective for most quaternary ammonium compounds, which are commonly used sanitizers in foodservice environments like Taco Bell. This range is effective in killing bacteria and viruses while being safe for use on food preparation surfaces.

Using a concentration within this range helps maintain the balance between disinfecting effectively and minimizing any toxic residues that could be harmful if ingested. Concentrations lower than 150 ppm may not provide sufficient sanitizing power, while solutions exceeding 200 ppm can lead to harmful chemical residue and potential health risks for customers. Therefore, the selected range directly supports food safety protocols critical in a restaurant setting.
