AB A questionnaire-based survey was distributed to the Office International des Epizooties (OIE: World organisation for animal health) Member Countries in Asia to assess the use of risk management for transmissible spongiform encephalopathies. The author presents a summary of 16 responses received in July 2002. The survey revealed that import risk analysis on bovine spongiform encephalopathy (BSE) is not routinely carried out in ten countries, indicating an urgent need for further training courses. Although the number of ruminants imported from Europe is relatively small, significant quantities of feedstuffs of ruminant origin have been imported into Asia, which may mean that the BSE agent could have reached domestic cattle in most countries. The external challenge has been considerably reduced in recent years as most countries in Asia banned the importation of feedstuffs from countries with BSE, but a few weak spots which enable imports of risk materials still persist. Recycling of BSE through rendering plants is unlikely but cannot be totally excluded in some countries such as the People's Republic of China, India, Japan, Pakistan and Taipei China. Therefore, much more stringent management at slaughterhouses and rendering plants, as well as extensive surveillance programmes, are required in those countries. Bovine spongiform encephalopathy is not notifiable in six countries, indicating a total absence of risk management of BSE in those countries. Immediate actions by these governments to declare BSE a notifiable disease are considered necessary. Numbers of specimens tested for BSE are still very small in most countries in Asia, indicating a pressing need to upgrade surveillance programmes by introducing modern (economically affordable) diagnostic methods and by conducting practical training courses on epidemiological surveillance systems. With the exception of Japan, very little work has been performed on scrapie in Asia although the disease has been routinely monitored in the People's Republic of China, India, Myanmar, Pakistan and Taipei China.
