What is the ideal concentration of bleach sanitizer for food contact surfaces?

The ideal concentration of bleach sanitizer for food contact surfaces is generally recognized to be between 50-100 parts per million (ppm). This concentration is effective in killing a wide range of pathogens while being safe for use on surfaces that come into contact with food. At this level, the bleach solution strikes an ideal balance, providing sufficient antimicrobial activity without posing significant risks for food safety or leaving harmful residues on surfaces.

When concentrations are too low, such as in options outside of this range, they may not adequately eliminate bacteria and viruses, increasing the risk of foodborne illness. Conversely, solutions that are too concentrated can not only be hazardous to health, possibly causing irritation or chemical burns, but may also damage or corrode food contact surfaces. Therefore, maintaining a concentration within the 50-100 ppm range is essential for ensuring both effectiveness and safety in food preparation and service environments.
