What is one disadvantage of iodine sanitizer?

The disadvantage of iodine sanitizer being expensive highlights a critical consideration in food safety practices, particularly for food establishments that rely on cost-effective solutions. Iodine sanitizers, while effective at killing bacteria and viruses, often come with a higher price tag compared to alternative sanitizers. This increased cost can impact budget-conscious operations, making it harder for them to maintain affordability while ensuring food safety.

Looking at the other options, the claim that iodine is ineffective in cold water is inaccurate; iodine can work effectively in various water temperatures, though it is generally recommended to use it in warmer conditions for optimal performance. The assertion that iodine works well at any temperature does not address a drawback; rather, it emphasizes the versatility of the sanitizer. Lastly, while iodine may have some environmental considerations, categorizing it as environmentally friendly does not align with industry standards, as many sanitizers may have varying impacts on the environment.

Thus, the answer reflects a valid concern regarding operational costs associated with the use of iodine sanitizers in food safety settings.
