BISMARCK, N.D. (AP) - North Dakota's Board of Animal Health is taking steps to control the spread of a new pig virus.

The virus known as PED was confirmed in a swine herd in eastern North Dakota Friday. The virus doesn’t affect people or food, but it’s killed more than 4 million pigs in the U.S.

The board is now requiring any pigs shipped into the state or within the state to have a health certificate stating there have been no clinical signs of PED or a similar virus known as TGE for the last two months on the premises where the pigs originated. State Veterinarian Susan Keller says the certificate must be signed by the pig owner and a veterinarian.

North Dakota Pork Council President Kevin Tyndall says the group supports the move.
