Distinguish between cleaning and sanitizing in the HACCP context.

• A. Cleaning removes soil and debris; sanitizing reduces microbial loads.
• B. Sanitizing removes soil and debris; cleaning reduces microbial loads.
• C. Cleaning removes soil and debris; sanitizing reduces microbial loads to acceptable levels.
• D. Cleaning removes soil and debris; sanitizing reduces microbial loads to acceptable levels; both require defined procedures, validation, and monitoring.

Answer: (D)

In HACCP, cleaning and sanitizing are two distinct steps that work together to keep surfaces safe. Cleaning is the physical and chemical removal of soil, food residues, and debris from equipment and surfaces using detergents and scrubbing. Sanitizing goes further by reducing the remaining microorganisms to levels that are considered safe or acceptable, typically through chemical sanitizers or heat treatment. For both activities, you need defined procedures documented and followed, validation to show the procedure actually achieves the intended effect, and ongoing monitoring to verify it continues to work. This combination—removing soil with cleaning, reducing microbial load with sanitizing, and controlling both through procedures, validation, and monitoring—best describes how cleaning and sanitizing function in HACCP.
