APHIS has approved the use of registry tattoos as official identification for the Scrapie Flock Certification Program from the following organizations: American Boer Goat Association, American Dairy Goat Association, American Goat Society, American Kiko Goat Association, Cashmere Goat Registry, International Boer Goat Association, International Fainting Goat Association, Miniature Silky Fainting Goat Association, National Pygmy Goat Association, Nigerian Dwarf Goat Association, Pedigree International, Pygora Breeders Association, and U.S. Boer Goat Association.
Scrapie is a fatal, degenerative disease affecting the central nervous system of sheep and goats. It is among a number of diseases classified as transmissible spongiform encephalopathies (TSE). Infected flocks that contain a high percentage of susceptible animals can experience significant production losses. Over a period of several years the number of infected animals increases, and the age at onset of clinical signs decreases making these flocks economically unviable. Animals sold from infected flocks spread scrapie to other flocks.
The presence of scrapie in the United States also prevents the export of breeding stock, semen, and embryos to many other countries. TSEs are the subject of increased attention and concern because of the discovery of bovine spongiform encephalopathy (BSE) in cattle, the link between BSE and variant Creutzfeldt-Jakob disease (vCJD) in people, and feline spongiform encephalopathy (FSE) in cats in Europe. See Factsheet for more detail.
