FEED OPERATIONS

The first step in protecting a mill is to understand the risk the
feed carries and potential pathogens that can be carried in feed.
Roger Cochrane, director of Feed Mills for Pipestone's nutrition team.
was contamination on equipment within
one meter of manufacturing and on surfaces more than three meters away.
Equipment had to be broken down,
power washed, sanitized and eventually
the mill was heated to 140 degrees F for
48 hours.
"It's not a process that is practical in the
industry and that's why we really focus
on prevention," Jones said. "Our options
if a pathogen moves into feed mills are
not pretty, they are not inexpensive and
are not very easy, and so there is quite a
bit of reward if we can continue to focus
on prevention because once we get into
feed mill mitigation, it's a whole other
ballgame of expense and impracticality."
A downfall of feed mill biosecurity is

the inability to guarantee complete success of no contamination.
"I think one of the things I struggle
with the most in the prevention aspect is
trying to help producers and feed manufacturers know and understand that
there is risk in feed manufacturing in
terms of virus transmission," Jones said.

probability of a pathogen coming in."
Determining the probability of a pathogen entering a feed mill depends too much
on each facility individually, including ingredient sourcing and processing.
"I would hedge my answer and say
there is enough risk that I think we have
demonstrated events where contaminated feed has caused swine illness in
North America," Jones said. "But there's
not enough evidence for us to build a

and that continues to be a challenge for
implementation."
