Study Notes

Sterilization and Disinfection

Sterilization is the process of completely eliminating or destroying all forms of microbial life, including spores and viruses, from a surface or object.
A sterilant is a chemical or physical agent used to achieve sterilization.

Disinfection and Sanitization

Disinfection is a process that reduces the number of pathogenic microorganisms, but not necessarily all microbial life, to a level that is considered safe for public health.
The primary difference between disinfection and sanitization is the level of microbial reduction, with disinfection aiming for a higher level of microbial kill.
The primary function of disinfectants is to destroy or inhibit the growth of microorganisms on surfaces or objects.
Sanitization aims to reduce the number of microbial contaminants to a safe level, making the surface or object suitable for public use or handling food.
