Starbucks Food Safety Practice Exam

Where should wiping cloths be stored when not in use?

1. In plain water

2. In a sanitizing solution with strength of 50 PPM

3. Stored dry

4. In a storage container

The correct answer is: In a sanitizing solution with strength of 50 PPM

Wiping cloths should be stored in a sanitizing solution with a strength of 50 PPM (parts per million) when not in use. This practice is essential for maintaining food safety and preventing cross-contamination. The sanitizing solution effectively kills harmful bacteria and pathogens that may be present on the cloths after they have been used to clean surfaces. This method ensures that the wiping cloths are ready for use and can help prevent the spread of foodborne illnesses. Storing them in a properly maintained sanitizing solution not only keeps the cloths clean but also helps preserve their cleanliness until they are needed again. Other methods of storing wiping cloths, such as keeping them in plain water or storing them dry, would not provide the necessary level of sanitation. Plain water does not have disinfecting properties, allowing pathogens to thrive. Dry storage does not prevent bacterial growth, especially if they have previously come into contact with contaminated surfaces. Using a designated storage container without a sanitizing solution may also fail to meet food safety standards, as it wouldn’t provide the necessary protection against contaminants.
