bial contamination and reduce risk of
pathogens in finished product.
Samples once collected in bare hands
and returned to the process following
inspection are now collected with clean
tools, inspected and disposed rather than
reintroduced into the processing system.
All of these efforts are considered necessary primarily to pass plant sanitation
inspections and to a lesser degree prevent microbial or contamination of food
product by human operatives.
PROCESSING AND PACKAGING
Processing and packaging of potentially
pathogen containing grain product has
become more important as the risks
have become more evident. At one time,
flour and other grain products were almost always processed through a kill
step either in a commercial facility or
at home, thought to eliminate pathogen
risks associated with the grain-based

product. Undoubtedly, employees or
consumers may have tasted product in
process and suffered few, if any, consequences connected with the grain-based
food product. Grain-based products increasingly are used in packaged cake
and cookie mixes, refrigerated or frozen
dough, including biscuits, pizza dough
and cookie dough ice cream products increasing the probability that the product
is tasted or ingested prior to any baking
or heat treatment that constitutes a kill
step. Food processors and consumer
awareness is ever increasing, and the bar
is being raised relative to their expectations of pathogen-free products in every
aisle of the grocery store, including the
baking aisle.
Over a decade ago, students in my
Mill Processing Technology Management class in the Department of Grain
Science and Industry at Kansas State
University were warned that one of

their biggest issues would be addressing
microbial pests in their facilities. It is a
paradox that the largest pests we spend
resources on to control in the grain processing industry are ones that can be
easily seen, while the pests not easily
seen, microorganisms and pathogens,
have the potential to cost dearly due to
recalls, litigation and consumer health.
Milling organizations, especially
those with consumer brand identity,
should be looking for pathogen mitigation technologies and implementation
before the consuming public, industrial
customers, or government agencies intervene.
