Starbucks Food Safety Practice Exam

For what purpose is a 50 PPM sanitizing solution typically used?

1. Wiping down surfaces

2. Immersion/soaking of utensils

3. As a cleaning agent

4. For washing hands

The correct answer is: Immersion/soaking of utensils

The use of a 50 PPM (parts per million) sanitizing solution is specifically suited for the immersion or soaking of utensils, which is a critical practice in food safety. This concentration is effective in killing bacteria and pathogens that can contaminate food or utensils, ensuring that any items that come into contact with food are sanitized appropriately. When utensils are submerged in a solution of this strength, it allows for full coverage, ensuring that all surfaces of the utensils are exposed to the sanitizing agent, which is necessary for effectively reducing microbial contamination. This immersion technique is standard in many food service environments, including Starbucks, to maintain hygiene and safety standards. Other choices may refer to different practices but do not align with the specific purpose of a 50 PPM sanitizing solution. For example, wiping down surfaces typically requires a different concentration for effectiveness as a sanitizer, while cleaning agents may contain detergents that are not suitable for direct immersion. Washing hands should also be conducted with soap and water rather than a sanitizing solution.
