What process destroys all microbial life?

• A. Sterilization
• B. Cleaning
• C. Exposure Incident
• D. Contamination

Answer: (A)

Sterilization is the process that destroys all microbial life on an object, including the most resistant spores. In practice, this level of control is achieved with methods like autoclaving (high‑pressure steam), dry heat, chemical sterilants, or irradiation. Cleaning, by contrast, just removes soil and reduces the microbial load; it does not guarantee that every microorganism is killed. An exposure incident refers to a potential contact with pathogens, not a method that eliminates all microbes. Contamination means microbes are present, not that they’ve been destroyed. So sterilization is the best answer because it achieves complete destruction of microbial life.
