Which statement best describes cleaning in sanitation?

• A. Solutions that destroy microorganisms or inhibit their growth on living tissue.
• B. Destroying most microorganisms on nonliving things by physical or chemical means.
• C. Destroying all microorganisms and viruses on an object using chemicals and/or heat.
• D. Physically removing all visible signs of dirt and organic matter such as feces, hair, etc.

Answer: (D)

Cleaning in sanitation means physically removing visible dirt and organic matter from surfaces or objects, rather than killing microorganisms. It uses water, detergents, and mechanical action to wash away soil like feces, hair, and debris. This step lowers the microbial load and is essential before disinfection, because organic material can shield microbes and reduce the effectiveness of disinfectants. The other ideas describe antisepsis (reducing or inhibiting microbes on living tissue) and disinfection or sterilization (killing or destroying microbes on inanimate surfaces), which are separate steps that come after cleaning. So the best description of cleaning is simply removing visible dirt and organic material.
