Starbucks Food Safety Practice Exam

What is the common use for a 100 PPM sanitizing solution?

1. Immersion/soaking of utensils

2. For deep cleaning floors

3. Wiping, spraying, or pouring

4. As a hand sanitizer

The correct answer is: Wiping, spraying, or pouring

The common use for a 100 PPM (parts per million) sanitizing solution is for wiping, spraying, or pouring. This concentration is effective for sanitizing surfaces and equipment without leaving harmful residues, making it suitable for use on food contact surfaces in a foodservice environment like Starbucks. A 100 PPM solution is specifically designed for routine sanitizing of surfaces that may come into contact with food or beverages. It helps to reduce the number of pathogenic microorganisms to safe levels, ensuring food safety and public health. This method is practical for quick application, allowing for efficient sanitation between cleaning processes. The other options relate to uses for similar but different concentrations or methods of sanitizing. Immersion or soaking of utensils generally requires a higher concentration of sanitizing solution to ensure effective sanitization throughout the items being cleaned. Deep cleaning floors is typically performed with stronger cleaning agents rather than just a sanitizing solution. As for hand sanitizers, they require specific formulations intended for skin use, which differ from solutions designed for surface sanitization.
