Touch
points are places touched by several persons multiple times
per day. Control of contamination and surface damage caused
by bacteria, mold and mildew are a serious concern for industry.
Touch points (human contact), floors, ceilings, overhead pipes,
passageways, process walls and doors are reservoirs for damaging
bacteria. It is a known fact that these microbes can live on
surfaces that appear to be clean. Microbial growth can be activated
by high moisture or temperature elevations. Standard cleaning
and sanitizing protocols are often ineffective in controlling
the growth of these microorganisms. There are two problems that
are often caused by common cleaning chemicals: first is the
adaptive nature of microorganisms to chemical attack. These
microbes are becoming increasingly more difficult to destroy.
The surviving microbes begin reproducing rapidly. Secondly,
chemical residues and dead microbes become a food source for
new microbes to feed upon and grow exponentially.
