Disinfectant Efficacy: How Can We Make It Effective?

 

Microorganisms are ubiquitous, and their numbers, as well as their diversity, is beyond comprehension. Also, as the sampling efforts increase, the number of novel phylotypes discovered continues to rise beyond prior estimates, and far beyond estimates for multicellular organismal diversity.1 This gives us an idea about the complexity, resilience, and evolutionary capability of the microbial world. It is important to keep this view of the microbial world in perspective when we are considering activities such as cleaning, sanitization, disinfection, and sterilization. In other words, removal or killing of microorganisms to keep our product and patient safety. In this article, the topic of disinfection and sanitization will mainly be covered and considered as a chemical agent. It will also be covered from the standpoint of their application being on environmental surfaces.

It is vital to understand the definitions of these terminologies of microbial reduction or killing. CDC describes disinfection as a process that eliminates many or all pathogenic microorganisms, except bacterial spores, on inanimate objects. Disinfectants are antimicrobials applied only to inanimate objects. Disinfectants are used in non-living surfaces, and objects to destroy or irreversibly inactivate infectious fungi, and bacteria but not necessarily their spores. The EPA has divided disinfectant products into mainly two major types:

 A. hospital type disinfectants are critical to infection control and are used on-medical and dental instruments, floors, toilet seats, and other surfaces;

 B. general use disinfectants are the main source of products in-households, swimming pools, and water purifiers.

 According to the CDC, a sanitizer is an agent that reduces the number of bacterial contaminants to safe levels as judged by public health requirements. Widely used with substances applied to inanimate objects.

 To receive a registration, a manufacturer must submit specific data about the safety and effectiveness of each product… The manufacturers suggest these data to EPA along with proposed labeling. If the EPA resolves the product can be used without causing „unreasonable adverse effects directions on each product (this is mainly applicable for healthcare workers utilizing the product).

 It is also important to note that in general, EPA regulates disinfectants and sterilants used on environmental surfaces, and not those used on critical or semi-critical medical devices; the latter are regulated by the FDA. Within the definition of the disinfectant and sanitizer, the words harmful/pathogenic/infectious are used because EPA has divided antimicrobial products into two categories based on the type of microbial pest against which the product works.
