Which is an example of "cleaning"?

In a professional foodservice environment, ServSafe makes a critical distinction between "cleaning" and "sanitizing." Cleaning is the physical process of removing food, dirt, and other visible soil from a surface. Removing food bits from a slicer with a wiping cloth is a direct example of cleaning. This step is the essential first phase in the five-step process for cleaning and sanitizing: (1) Scrape or remove food bits, (2) Wash the surface, (3) Rinse the surface, (4) Sanitize the surface, and (5) Allow the surface to air-dry.

Without the initial cleaning step, the subsequent sanitizing step will be ineffective. Soil and food particles can neutralize chemical sanitizers like chlorine or quaternary ammonium, or they can act as a physical shield that prevents the sanitizer from reaching and killing microorganisms. Options A and B describe monitoring and the act of sanitizing, respectively. Option D is a cosmetic action(polishing) that does not necessarily meet the hygienic definition of cleaning in a food-safety context. Effective cleaning requires the use of a detergent and physical labor (scrubbing or wiping) to break the surface tension of the soil. For equipment like meat slicers, this process is high-risk and must be performed at least every four hours if the equipment is in constant use. Managers must verify that staff are not skipping the "wash and rinse" phases before applying sanitizer. By removing the visible "bits" and "grease," the food handler ensures that the environment is prepared for the reduction of pathogens to safe levels.
