Which term describes a cleaning process that reduces surface pathogens but does not kill bacteria?

• A. Disinfection
• B. Sanitation
• C. Purification
• D. Sterilization

Answer: (B)

Sanitation refers to cleaning that reduces surface pathogens to safe levels without eliminating every bacterium. It focuses on lowering the microbial load to a level considered safe for public health, rather than achieving complete eradication. This distinguishes it from disinfection, which aims to destroy or inactivate most pathogens on surfaces (though some bacteria may remain), and from sterilization, which eliminates all microbial life, including spores. Purification isn’t the standard term used in this context. So, the process described—reducing pathogens without killing all bacteria—is sanitation.
