GENETIC TESTING OFFERED TO FIGHT SHEEP DISEASE West Virginia sheep producers are encouraged to have their rams tested for a genetic susceptibility to a transmissible spongiform encephalopathy (TSE) illness called scrapie. The West Virginia Department of Agriculture (WVDA) is offering the service free of charge as part of a national program aimed at eradicating scrapie. “A simple blood test can determine if a ram is able to pass genetic resistance against scrapie,” said State Veterinarian Joe Starcher. “Rams that have been tested and are known to carry resistant genes, make ideal breeding stock.” The long–term goal of the program is the nationwide eradication of scrapie, which annually causes significant loss of production in infected flocks. “Scrapie has plagued the farmers of this state for a long time,” said Commissioner of Agriculture Gus R. Douglass. “I hope our producers will take advantage of this program, which can go a long way toward eradicating this disease.” To participate in the program, producers must contact the WVDA’s Division of Animal Health Moorefield Office at (304) 538-2397 or Charleston Office at (304) 558-2214 or their local veterinarian. Local veterinarians and the WVDA will work together to implement this innovative program. Scrapie is a fatal, degenerative disease affecting the central nervous system of sheep and goats. First documented in Great Britain and other countries of Western Europe more than 250 years ago, scrapie has been reported throughout the world. Only two countries are recognized by the United States as being free of scrapie: Australia and New Zealand. Scrapie has been diagnosed in more than 1,000 flocks in this country. Scrapie – so named because one symptom of the disease involves rubbing against fence posts and the like – is classified as a transmissible spongiform encephalopathy (TSE), the same kind of malady that causes mad cow disease in cattle, chronic waste disease in deer and elk, and Creutzfeldt-Jakob disease in humans. Epidemiologic evidence does not support that scrapie in sheep and goats may be transmitted to humans through contact on the farm, at slaughter plants, butcher shops, or through the consumption of sheep or goat meat/milk products. The primary method of transmission is by contact and oral ingestion of placental or fetal fluids. Thus, proper disposal of any fetal tissues from suspected animals should be handled with the utmost biosecurity measures.

The Commissioner of Agriculture is one of six statewide elected officials in West Virginia. Currently, Commissioner Gus R. Douglass is the longest-serving agriculture commissioner in the nation.
