What must the third compartment in the three-compartment sink be filled with?

• A. Cold water
• B. Hot water
• C. Water and Sanitizer
• D. Dish soap and water

Answer: (C)

The third compartment in a three-compartment sink must be filled with water and sanitizer. This is essential for the proper sanitization of dishes, utensils, and equipment after they have been cleaned in the first two compartments. The first compartment is used for washing with detergent, while the second is designated for rinsing. The third compartment, filled with a sanitized solution, serves to kill any remaining bacteria that may be on the items.

Using a water and sanitizer solution not only helps ensure that all surfaces are effectively sanitized but also complies with health regulations that require food service establishments to maintain hygiene standards. Different sanitizers have specific dilution ratios and contact times that need to be followed to ensure effectiveness, ensuring that the items are safe for use in food preparation and service.

Other choices, such as cold or hot water alone, or soap, would not achieve the critical sanitization needed for preventing foodborne illnesses. Thus, filling the third compartment with water and sanitizer is paramount for safe food handling practices.
