Which process reduces microbial load on objects to a safe level?

• A. Disinfection
• B. Antisepsis
• C. Sterilization
• D. Sanitization

Answer: (D)

Sanitization lowers microbial load on objects to a level considered safe for their intended use. It focuses on reducing contaminants to a point where the item is safe to handle or use, rather than eliminating every microorganism.

Disinfection aims to kill or inactivate most disease-causing organisms on inanimate surfaces but may not remove every microbe or guarantee sterility. Antisepsis applies antimicrobial agents to living tissue to prevent infection. Sterilization is the complete elimination or destruction of all forms of microbial life, including spores, on an object. For everyday cleaning where the goal is safe handling rather than total sterility, sanitization is the appropriate concept.
