Jerome Geiger, DVM, PIC-China, and Joe Connor, DVM, Carthage (IL) Veterinary Service Ltd., have collaborated to produce a white paper outlining the appropriate procedures for the diagnosis and elimination of the porcine epidemic diarrhea (PED) virus.

The paper, entitled Porcine Epidemic Diarrhea, Diagnosis, and Elimination, is based on their work with PED virus in China, where the disease has existed for decades. It contains a thorough description of a protocol for the herd-level elimination of the virus.

“Veterinary teams know how to eliminate TGE virus. I see no reason why we would not be successful in eliminating this virus from our herds in a similar manner,” Connor says.

Warm weather facilitates virus deactivation, so the summer months present a good time to launch a PED virus elimination plan.

Granted other countries have not had much success cleaning up PED virus. But in the United States, segregated production systems provide a level of separation that will facilitate elimination of the virus, Connor says.

However, cleanup of farrow-to-finish operations infected with PED virus will be more challenging. “We may have to develop a gap in production to protect susceptible populations to make that successful,” he says.
