According to most health codes, what is the minimum ppm of chlorine for sanitizing solutions?

The minimum parts per million (ppm) of chlorine required for sanitizing solutions is 100 ppm. This concentration is crucial for effectively sanitizing food contact surfaces, as it ensures that harmful pathogens are eliminated to prevent foodborne illnesses. Chlorine works as a disinfectant, and at this level, it is strong enough to kill bacteria, viruses, and other microorganisms that can contaminate food and surfaces.

Health codes are established based on research that determines the efficacy of sanitizing agents at various concentrations. A chlorine concentration of 100 ppm has been found to strike a good balance between effectiveness and safety, ensuring that surfaces are effectively sanitized while minimizing the risk of harmful chemical residues affecting food.
