The role of harvest plant lairage and
transportation in propagating the initial
stages of an outbreak of Porcine
Epidemic Diarrhea Virus in the United
States in 2013.

What we learned
1. Trailers can become contaminated at packing
plants but less than one clean trailer is
contaminated for each contaminated trailer that
arrives a the plant.
2. There is contact by EVERY driver with the plant
lairage and that appears to be sufficient to allow
for PEDV movement between trailers.
3. More contact between trailer and plant is
associated with higher rates of PEDV spread
Illinois Rapid Response Team - Risks
• Air – low
• Spread by humans – moderate
• Vehicles or other equipment – moderate
• Pig movements – negligible
• Water – ‘not likely’
• Feed pellets – moderate
• Bedding materials – low
Ohio Rapid Response Team - Risks
• Spread by workers – low
• Vehicles or other equipment – low
• AI or veterinary supplies – negligible
• Pig movements – low
• Feed ingredients / commercial meal mix –
‘not likely’
• Feed pellets – high
• Water, air, shavings – negligible
Feed Risk – What Do We Know?
• PED is not a human health or food safety issue.
• The disease is impacting farms of a variety of sizes and
production types and needs to be prevented through a
variety of biosecurity procedures.
• PCR is an important tool to use in assessing contact with
the virus
• There are multiple methods of PED transmission
including environmental, transportation, feed systems
and other vectors.
Feed Risk – What Do We Know?
• Within processing feed ingredients and feed processing
there is a time x temperature that should be effective in
inactivating the virus
• Post processing contamination can occur in different
segments of the feed supply chain
• Pork industry stakeholders, veterinarians, producers,
nutritionists and feed processors, agreed to a disciplined
research approach to attack PED
