What concentration range is required for iodine sanitization?

The required concentration range for iodine sanitization is 12.5-25 parts per million (ppm). This concentration is effective in killing a wide range of microorganisms, including bacteria, viruses, and fungi, making it suitable for sanitizing food-contact surfaces in foodservice environments like Starbucks.

Using iodine at this concentration ensures that the sanitization process is both effective and safe, as it minimizes the risk of harmful residues that could affect food safety and quality. Maintaining the correct concentration is critical; too low may not effectively sanitize, while too high could lead to potential contamination and safety concerns.
