Which of the following terms refers to a cleaning method that is not entirely effective against all pathogens?

The term that refers to a cleaning method that is not entirely effective against all pathogens is sanitation. Sanitation typically involves reducing the number of microorganisms on a surface to a safe level as determined by public health standards, but it does not necessarily eliminate all pathogens. This makes it a crucial process in maintaining hygiene, especially in settings where food is prepared or where the health of individuals is a concern.

In contrast, the other terms refer to methods that have different levels of effectiveness against pathogens. Cleaning involves the removal of dirt and debris but doesn’t effectively kill or eliminate germs. Decontamination is a broader process that may include both cleaning and sanitizing and can refer to making a surface safe, but it doesn’t guarantee the complete destruction of pathogens. Disinfection involves killing a significant number of pathogens, specifically targeting harmful microorganisms and rendering them inactive, showing a higher efficacy than sanitation. Thus, sanitation is distinct in that it addresses the reduction of microorganisms rather than complete eradication.
