Federal Processors PEDv
This information was presented at an Ontario Pork Processor Porcine
Epidemic Diarrhea (PED) Cleaning and Disinfection Planning Session
February 1, 2014.
Key Points To Remember
- This is a big deal!
- This is serious both for us and our suppliers.
- Actions now will affect the spread of this disease and its
long-term economic impact
- PEDv is not a food-safety issue for humans.
- PEDv only infects swine, though other species can physically
spread it around.
- The Federally Inspected plants will be receiving known-positive
PEDv hogs as long as they are not clinically ill at the time of
- We will require these hogs to be delivered at specific times
to allow clean-up and disinfection of our facilities before other
- We will not discriminate against producers with PEDv positive
hogs and we will cooperate fully with Ontario Pork, OMAF and producers.
- Our goal is to make sure that trucks leave our plants no worse
than they arrived. In other words, if a truck arrives without
the virus, we want it to leave without the virus.
- We can't control possible PEDv to our plant so every area of
our facilities should be considered as potentially contaminated
with PEDv. This includes offices and walkways.
- We need to assume that every truck has the potential to be
carrying the virus.
- As of now, we believe that few trucks are carrying it, but
we don't know which until after they have unloaded and tests have
been completed. This may take up to 36 hours.
- We expect to test each truck after unloading so we can identify
new pockets of PEDv infection.
- Test results can be returned quickly, so producers provide
appropriate biosecurity enhancements
- At this stage of the outbreak, intensive effort may contain
- PEDv does not lose viability quickly
..weeks or months
in cold weather
Another View of Biosecurity
- The Wet Paint Example
- Think of two areas
one clean and painted green and one
with fresh, wet, red paint.
- Think of hog trailers and tractors as "green".
- Consider everything else in and around a processing plant as
covered with red wet paint.
- This means Everything
areas around loading chutes, receiving
offices, driveways, walkways, loading docks, lunchrooms, washrooms,
slaughterhouse pens, all covered in wet red paint.
- Your goal is to keep the green area totally free of any red
none at all.
Plant Receiving Dock Example
Figure 1. Keep what you need inside the "green"
equivalent to Figure 1
Red or pink areas all should be considered contaminated and require
protection to cross on foot.
Arrows show where we want to avoid contamination moving
How to Keep the Red Out
- Wear special boots in "Red" areas but change them
when going into "Green" areas.
- Good plan but a single step into the red paint with your "Green"
area boots causes contamination.
- Boot dips are not effective at cleaning "Red" boots.
You have to keep them away from contact with the wet red paint.
- Paddles, Crowding Boards, also can get Red on them.
- Keep what you need inside the "Green" trailer space.
Federal Plant Implementation
- Each plant has put special procedures in place and as the situation
develops, the procedures will be adjusted.
- Depending on the plant, these may include:
- Providing plant boots at the running board of arriving
trucks and requiring drivers to stay in their cabs until the
plant boots are there for them to use as they step onto the
- These boots are to be worn while walking in the yard, office
or receiving dock at the plant. (the "red paint areas").
This will require extra resources from the plant to handle
moving boots around.
- Drivers must bring a tote box containing boots that are
as clean as the inside of the trailer they are delivering.
- The driver will change to his own clean boots as he enters
the trailer. The clean "Green" boots must never
touch any red area. If drivers need to leave the trailer for
any reason they must change back into the "red"
boots on the dock.
- This may not be possible at all plants and will cause some
- Drivers need to store crowding boards, paddles etc inside the
trailer. No plant supplied equipment should go into the "Green"
- Drivers and plant receivers must ensure no animals return from
the dock back onto the trailer.
- Plant employees and Inspectors must not enter the trailer at
any time unless they have put on clean coveralls and fresh, clean,
previously disinfected boots before entering (not boots considered
to be "red"). Disposable coveralls should be used to
ensure that there is no re-use of "red" smeared coveralls
- When drivers return to their truck cab area they must remove
their "red" boots and put on their driving boots positioned
on the first step of their running board. They should consider
the driveway, or yard area as contaminated and still covered with
wet red paint. Other "red" areas likely include restaurants
favoured by livestock drivers
Even More Details
- All plants provide daily washing and will add disinfection of
unloading and receiving areas
- At least one plant will install winches to remove DOA or Euthanized
hogs from trucks
- No visitors will be allowed in or around barn areas
- Restrictions on movement, and boot policy for staff and CFIA
inspectors will be added if it is not operating already
- Plants are investigating modified Danish entry systems and
rapid wash systems for dock surfaces.
- Heroic efforts implemented now, by everyone, may allow us to
contain this disease.
- One by one each of us needs to support the effort by taking
care and paying attention to the fine details of Biosecurity.
- Thank you to all of the first responders who have done their
homework and worked tirelessly over the past 2 weeks
