Final answer:
None of the options provided (Meat grinder, Cheese slicer, Cafeteria tray, Cutting board) should be cleaned without also being sanitized. These items can harbor bacteria and contribute to cross-contamination,
Step-by-step explanation:
The following surfaces need to be cleaned and sanitized to prevent cross-contamination and ensure food safety: A. Meat grinder, B. Cheese slicer, C. Cafeteria tray, and D. Cutting board. These items come into direct contact with food and, depending on the foods they touch, could be exposed to harmful bacteria such as Salmonella or E. coli.
Cross-contamination is a serious concern in food preparation areas because it can lead to foodborne illness. Items like a meat grinder or a cheese slicer can retain food particles in their mechanisms, creating a breeding ground for bacteria. Cafeteria trays and cutting boards are high-touch surfaces that can transfer pathogens from one place to another if not properly sanitized between uses.
Therefore, none of the options provided (A, B, C, or D) can be cleaned without also sanitizing before use. Sanitizing these items will reduce the microbial load to safe levels, helping to prevent foodborne illness and ensuring a safe eating environment.
