Which phrase best defines sterilization?

Which phrase best defines sterilization?

• A. Free of all microorganisms
• B. Destruction of most pathogens
• C. Reduction of microbial load
• D. Temporary preservation

Answer: (A)

Sterilization means eliminating all living microorganisms, including hardy spores, from a surface or inside a product. That’s why the phrase “free of all microorganisms” is the best definition—any surviving viable organism would mean the item isn’t sterile. This sets sterilization apart from disinfection, which aims to destroy most pathogens but not necessarily every organism, and sanitization, which lowers the overall microbial load to safe levels. Temporary preservation is unrelated to microbial control. Sterilization is achieved through methods like autoclaving, dry heat, radiation, or chemical sterilants.
