Microbes in the Environment
"[The] ability to inactivate microbes in the environment on a continuous basis is important because bacteria, including MRSA, can survive in a variety of conditions for long periods of time and can spread via dust particles, clothing, furniture, or hospital equipment that have been in contact with infected patients..."

"Log reduction" is a mathematical term (as is "log increase") used to show the relative number of live microbes eliminated from a surface by disinfecting or cleaning.
For example, a "5-log reduction" means lowering the number of microorganisms by 100,000-fold, that is, if a surface has 100,000 pathogenic microbes on it, a 5-log reduction would reduce the number of microorganisms to one.
The Cleaning Industry Research Institute (CIRI) is a 501.c.3 not-for-profit scientific, educational and research organization that applies science to the practice and improvement of cleaning and maintenance.
