The correct sanitizer concentration level for the back sink area is within the range of 200-300 ppm. This concentration is deemed effective for sanitizing surfaces and ensuring that harmful bacteria and pathogens are effectively eliminated.

Maintaining a sanitizer concentration at this level is crucial for food safety in a food service environment like McDonald's, as it strikes a balance between efficacy and safety. A lower concentration may not effectively kill all pathogens, while a higher concentration can lead to residue that may not be safe for food contact surfaces. Thus, the chosen range guarantees that sanitization meets regulatory standards and supports proper hygiene practices in the kitchen, decreasing the risk of foodborne illnesses.
