On food-contact surfaces, what is correct order and purpose?

• A. Cleaning removes soil; sanitizing reduces pathogens; clean first, then sanitize
• B. Sanitizing removes soil; cleaning reduces pathogens
• C. Cleaning only is sufficient
• D. Sanitizing only is sufficient

Answer: (A)

The essential idea is to use two steps in a specific order to properly reduce contamination on surfaces that will touch food. Start with cleaning to remove soil like food residues, grease, and dirt. This physical removal with detergents loosens and rinses away debris so the surface is clean. Then apply sanitizing to kill or inactivate remaining microorganisms to safe levels. The reason for the order is that soil on a surface can shield pathogens and also interfere with the effectiveness of sanitizers; cleaning first ensures the sanitizer can work properly and reach microbes. If you sanitized first, you’d be treating a dirty surface, which is less effective and could leave residues that harbor bacteria. Relying on only one step—either cleaning alone or sanitizing alone—doesn’t reliably make the surface safe for contact with food.
