BISMARCK, North Dakota — North Dakota's state veterinarian is ordering that all swine coming into the state have a health certificate declaring the animals have not been exposed to porcine epidemic diarrhea virus.
Dr. Susan Keller says the certificate also must declare the animals do not originate from a location that is known to be affected by PEDv.
Keller says the action is due to more cases in surrounding states and Canada. She says the mortality rate in young swine is up to 80 to 100 percent, and production losses are significant in older swine.
The health certificates must be signed by the owner of the animals and the issuing veterinarian.
PEDv causes severe diarrhea, dehydration and vomiting in pigs.
The virus has not yet been identified in North Dakota.
