What are the correct sanitizing concentrations for chlorine bleach?

The correct sanitizing concentration for chlorine bleach is essential for effectively reducing the number of pathogens on food contact surfaces to safe levels. A concentration of 50-200 parts per million (ppm) is widely recognized as effective for sanitization purposes. This range balances effectiveness in killing bacteria and viruses while ensuring safety for food preparation surfaces.

Using a concentration below 50 ppm may not effectively eliminate harmful microorganisms, while concentrations above 200 ppm can lead to potential chemical residues on surfaces and create risks for human health, as well as damaging the surfaces that are being sanitized. Thus, the concentration of 50-200 ppm is recommended by health organizations for proper sanitation in food service environments, ensuring food safety and hygiene standards are met.
