Which of the following is NOT a function of sanitization?

Sanitization primarily focuses on reducing the number of microorganisms on surfaces to safe levels as defined by public health standards. This process involves removing dirt, reducing contamination, and, in some cases, eliminating pathogens, although not always to the degree that achieves sterility.

The creation of a sterile environment, however, goes beyond the scope of sanitization. Sterilization is a more rigorous process that completely eradicates all forms of microbial life, including bacterial spores, and is typically used in medical and laboratory settings where a sterile field or equipment is necessary. Therefore, the act of establishing a sterile environment does not fall under the standard functions of sanitization, which aims primarily at cleanliness and safety rather than absolute sterility.
