What is the sanitizer concentration requirement for iodine as a chemical sanitizer?

The correct sanitizer concentration requirement for iodine as a chemical sanitizer is between 12.5-25 ppm (parts per million). This concentration range is critical for effectively killing bacteria and ensuring that surfaces are sanitized without leaving harmful residues.

Using iodine within this specified range is supported by guidance from food safety authorities, who emphasize that this concentration effectively eliminates pathogens while being safe for food-contact surfaces. It is important to maintain this concentration because concentrations that are too low may not adequately sanitize surfaces, thereby posing a food safety risk, while concentrations that are too high can leave unwanted chemical residues and potentially affect the taste or safety of food.

In food service environments, proper monitoring of sanitizer concentrations is essential to ensure compliance with safety regulations and to protect public health.
