Regardless of great numbers of embryo exports to various countries since 1994, no case of disease transfer has so far been reported. As far as small stock is concerned, the RSA is free of foot-and-mouth disease, Scrapie, CAE, sheep and goat pox, Nairobi sheep disease and Contagious Caprine Pleuropneumonia.
South Africa is therefore one of the few countries worldwide that is Scrapie-free. Blue tongue is the only disease really endemic to Africa and that should be handled with caution. The Onderstepoort Veterinary Institute has developed a reliable test for ensuring the absence of the blue tongue virus. Rift Valley fever last occurred in South Africa in 1974 and a reliable test is available for ensuring negative donors.
