Oregon State Veterinarian Dr. Brad LeaMaster, D.V.M., has confirmed the presence of Porcine Epidemic Diarrhea virus (PEDv) on a farm In Clackamas County, Ore.. The infected premise has been quarantined and Oregon Department of Agriculture is conducting an epidemiology investigation to the sourced farm.

Washington State Veterinarian Dr. Joe Baker, D.V.M., has been in contact with LeaMaster and is monitoring the situation. At this time, Baker indicated that there is no cause for alarm for pig farms in Washington.

Pig farmers are encouraged to maintain strict biosecurity measures on their farm and when purchasing pigs. Owners should contact their veterinarian for assistance with diagnosis, vaccination, disinfection, and other PEDv mitigation details.

In addition, any swine shipments entering Washington must be accompanied by a valid Certificate of Veterinary Inspection (CVI or AKA health certificate) declaring that the pigs have not been exposed to PEDv-and are disease-free.

The certificate must declare the pigs did not come from anywhere know to be infected with PEDv. The certificate must be signed by both a licensed veterinarian and the animal owner. The CVI is required for all pigs entering Washington not going directly to slaughter, including show pigs, feeder pigs, breeding pigs, and pet pigs.

If you have questions about importation of pigs into Washington please contact the Washington State Department of Agriculture Animal Service Division at (360) 902-1881.

The National Pork Board has an excellent set of resources concerning PEDv available at http://www.pork.org/pork-checkoff-research/pedv/pedv-resources/. Resources cover PEDv basic and diagnosis, on-farm strategies, transportation strategies, manure strategies, and show pig strategies.
