How is sanitation related to microbiology?

Answer 1

Sanitation is making something 'free from "germs"'. "Germs" is the layman term for microorganisms that cause disease. Not all, in fact very few, microorganisms found in nature cause disease. Bacteria, parasites and generally viruses are considered to be microorganisms. Generally sanitation refers to food, toilets and other areas that may become contaminated with disease causing microorganisms. Good sanitary practices involve washing your hands after using the toilet (since faeces contain Enterobacteriacaea and E. coli, to name a few), cleaning benches used for food preparation and wearing gloves, etc. However, sanitation, or keeping things clean is not the only way to prevent infection by disease causing microorganisms from proliferating. Refrigerator temperatures should always be kept low and meat should always be cooked to a safe standard.

Answer 2

It is the type of science that allows a septic tank to function.
