Which process destroys most pathogenic bacteria and toxins on nonporous surfaces?

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

Answer: (C)

Disinfection is the process that reduces or inactivates most pathogenic bacteria, viruses, and many toxins on surfaces. On nonporous surfaces, the smooth, sealed texture allows disinfectants to contact microbes more effectively, so with proper contact time and concentration they substantially lower the microbial load and inactivate toxins. This level of control is more thorough than sanitation, which aims to lower counts to safe levels but may not eliminate most pathogens, and it’s less extreme than sterilization, which wipes out all microorganisms including spores and is typically reserved for critical instruments. Contamination isn’t a process at all; it’s the presence of pathogens. So disinfection best fits the goal of destroying most pathogenic bacteria and toxins on nonporous surfaces.
