In sanitizing machinery, what indicates that the iodine sanitizer is working correctly?

The correct choice is based on the ideal concentration range for iodine sanitizers, which is crucial for effective sanitization. A concentration of 12.5 to 25.00 parts per million (ppm) indicates that the iodine solution is at the right strength to effectively kill bacteria, viruses, and other pathogens on the surfaces being sanitized.

Maintaining this concentration is essential for ensuring that the sanitizer can work effectively without compromising food safety. If the concentration is too low, it may not be effective in achieving the desired level of sanitation; if it is too high, it could leave harmful residues or impart an undesirable taste to food items. Therefore, monitoring the ppm of the iodine sanitizer during operation is a reliable way to confirm that it is functioning correctly and will maintain safe food-handling practices.
