Wendys Training Practice Test

What is the minimum time an iodine sanitizer solution must be in contact with the object being sanitized?

1. 10 seconds

2. 30 seconds

3. 60 seconds

4. 90 seconds

The correct answer is: 30 seconds

The correct answer is based on food safety protocols regarding the use of iodine as a sanitizer. For effective sanitation, an iodine solution must remain in contact with the surface or object being sanitized for at least 30 seconds. This timeframe allows for adequate disinfection, ensuring that harmful pathogens are effectively killed. Sanitizers like iodine require a specific contact time to work optimally, and 30 seconds is the minimum time recommended in many health and safety guidelines for proper sanitation. Other durations, whether shorter or longer, do not align with established practices for iodine sanitization. A shorter contact time may not allow the sanitizer to effectively eliminate microorganisms, while longer times, although still effective, are unnecessarily prolonged for standard sanitization practices.
