debris. Another type of dry cleaning utilizes vacuum technology. Dust and debris can harbor environmental pathogens
such as Salmonella. Traditional dry cleaning methods using
compressed air can expand the spread of such pathogens.
Modern techniques often utilize centralized vacuum systems
and mobile vacuum backpacks to access hard-to-reach areas.
Dry steam cleaning utilizes superheated steam (~212–240 °F)
via nozzles to directly apply heat to surfaces, greatly reducing
the water needed and generating almost no wastewater runoff.
Many companies have started using dry sterilant gases (e.g.,
ozone, chlorine dioxide, hydrogen peroxide vapor) to accompany traditional cleaning.
Observing sanitation and noting how long water is used in
a certain area is an easy
way to begin a water-re-duction initiative. Certain surfaces could be
better cleaned utilizing
a cloth and sanitizer/
electrical boxes, control
panels and areas around
This practice might be
more labor intensive
but will certainly be
gentler on sensitive
equipment. There are
ways of possibly reducing sanitation labor.
to identify equipment that could be further broken down during daily or periodic sanitation can make this process more
efficient. Trend your preoperational observations and microbiological surface testing to better understand your problem
areas and make accurate decisions on the proper cleaning frequency in different parts of the plant. Once you’ve exhausted
your in-house talent, sanitation consultants may offer further
aid. Many companies bring in experts to streamline sanitation practices, including overhauling enclosed clean-in-place
systems to ensure maximum efficiency and reduce use of unnecessary water and chemicals.
Lastly, both CSR and FSQ practitioners share an unprecedented proclivity toward collaboration. Even among direct
competitors, leaders in these fields are the first to share innovations, encouraging others to adopt best practices. In an
extremely competitive business, there’s a drive for continuous improvement, not just for individual companies but
also for the entire field. Conferences are held solely to share
this knowledge. For example, the International Association
of Food Protection brings industry leaders from around the
