What must you do to contact surfaces when switching to a different task or food type?

• A. Cleaned and Sanitized
• B. Cleaned Only
• C. Sanitized Only
• D. Rinsed and Air-Dried

Answer: (A)

Switching tasks or foods requires removing both soils and microbes from contact surfaces to prevent cross-contamination. Cleaning uses a detergent to lift and remove dirt, grease, and residues. Sanitizing then reduces the remaining microbes to safe levels. Doing both in sequence—clean first, then sanitize—gives you a surface that's ready for the next task or food type. Rinsing and air-drying alone don’t sufficiently remove soils or kill microbes; sanitizing alone can be less effective if soils shield germs, and cleaning alone leaves microbes behind. So, the best practice is to clean and sanitize.
