Control and eradication of animal diseases in New Zealand.
New Zealand is free from all the major epidemic (Office International des Epizooties List A) diseases of animals and other important diseases, such as rabies and the transmissible spongiform encephalopathies. The once endemic conditions of sheep scab (Psoroptes ovis), bovine brucellosis (Brucella abortus), hydatids (Echinococcus granulosus) and Aujeszky's disease have been eradicated. Anthrax (Bacillus anthracis) is no longer considered endemic and Pullorum disease (Salmonella Pullorum) has effectively been eradicated from commercial poultry flocks. There are current control programmes for bovine tuberculosis (Mycobacterium bovis), enzootic bovine leucosis in dairy cattle, infectious bursal disease, ovine epididymitis (Brucella ovis), and caprine arthritis encephalitis. Historically, incursions by three important non-endemic diseases, contagious bovine pleuropneumonia, classical swine fever and scrapie, have been successfully eliminated. Any new occurrence of a serious exotic disease would be dealt with swiftly using powerful legislative authorities available for the purpose.
