What is the third sink in a three-compartment sink setup used for?

In a three-compartment sink setup, the third sink is designated for filling with water and sanitizer at the correct concentration. This is essential in the process of sanitizing dishes and utensils after they have been washed and rinsed in the first two compartments. The use of sanitizer is crucial to eliminate any remaining bacteria or pathogens, ensuring that the items are safe for food service.

Proper sanitation is a fundamental practice in food safety, as it helps prevent foodborne illnesses. Following the washing process, items are submerged in the sanitizer solution for a specific amount of time, which will effectively eliminate harmful microorganisms. The correct concentration of sanitizer is critical to ensuring that it is effective; if the concentration is too weak, it may not kill pathogens, while too strong a solution could potentially harm the dishes or leave harmful residues.

This understanding of the three-compartment sink's function reinforces the importance of maintaining cleanliness and sanitation standards in any food service environment, such as Starbucks.
