Dr. Walla of the World Health Organization praised the prevention and control of BSE in China

Introduction: not long ago, the Ministry of Agriculture issued a notice that the results of national BSE surveillance showed that there was no BSE in China Dr Wala, director general of the world organization for animal health (OIE), gave a thumbs up and praised the work of China's national BSE testing center Since the first case of BSE was found in England in 1986, BSE has occurred in more than 20 countries in the world, but it has not yet happened in China This is undoubtedly good news Some readers wrote and called, interested in the reasons why there was no BSE in China Reporter recently interviewed Jia Youling, director of animal husbandry and Veterinary Bureau of the Ministry of agriculture on this issue "Mad cow disease", commonly known as bovine spongiform encephalopathy (BSE), is a progressive, highly lethal and neurological disease of adult cattle According to experts, the main way of transmission of BSE is to feed cattle with protein feed such as meat and bone meal with BSE and ovine itch pathogen, and the disease can be transmitted to people through cattle derived food Jia said that the root cause of the absence of BSE in China is that the Chinese government attaches great importance to the prevention and control of BSE Since 1990, a series of measures have been taken to effectively prevent the introduction and occurrence of BSE First of all, the import approval and quarantine supervision of animal and animal origin products have been strengthened, such as strictly prohibiting the import of cattle and sheep, beef and sheep meat and bone meal and other related products from countries or regions with BSE and itch disease, as well as biological products containing ruminant tissue ingredients, and prohibiting the import of animal feed products from countries with disease origin Since 2000, the Ministry of agriculture, AQSIQ, the General Administration of customs, the Ministry of health, the State Drug Administration and other departments have all implemented strict restrictions or prohibitions on the culture medium, ruminant derived food, cosmetics, drugs and medical devices imported from countries (regions) with BSE and EU Member States Secondly, the management of feed production and use has been strengthened, and strict regulations have been made on the production, storage, transportation, packaging and other links of ruminant feed, and it is expressly prohibited to feed ruminant with animal source feed This is equivalent to cutting off the transmission of BSE completely At the same time, the surveillance of BSE was strengthened The Ministry of agriculture has listed BSE as the focus of prevention of exotic animal diseases According to the relevant standards of the world organization for animal health, it has implemented active monitoring and passive detection For example, the animal husbandry and veterinary departments of all provinces (autonomous regions and municipalities directly under the central government) were organized to investigate the risk factors of BSE After a comprehensive follow-up investigation and long-term key monitoring of all cattle (including embryos and their offspring) imported since 1990, no typical BSE symptoms have been found 4276 bovine brain tissues were collected nationwide (according to the world organization for animal health, the minimum number of tests in China is 1200) The results were negative after laboratory tests With the development of prevention of BSE, the reserve of BSE prevention technology in China has been strengthened In 1999, the Ministry of Agriculture established the national BSE testing center, and last year, it established the BSE testing laboratory in China Agricultural University It cooperated with the international reference laboratories of BSE in Switzerland, Britain and other countries to carry out the research on BSE control The national animal husbandry and veterinary system has also carried out a wide range of dissemination activities of BSE knowledge, providing strong technical support for the general survey and monitoring of BSE The China Center for Disease Control and prevention, affiliated to the Ministry of health, has also set up a prion disease detection and diagnosis center to detect the samples sent by patients with clinically suspected variant "Creutzfeldt Jakob disease" (Note: people who eat beef with BSE or use products containing BSE pathogen may suffer from this disease) Beijing entry exit inspection and Quarantine Bureau has also set up a BSE laboratory In view of the fact that BSE is a disease with high risk, it is strictly forbidden for any unit or individual to engage in research on BSE without approval Jia Youling said that although no BSE has been found in China at present, we should not relax the epidemic prevention of BSE China will continue to carry out active monitoring of BSE, effectively prevent the introduction and occurrence of BSE, and ensure the safety of animal products in China (author:) share to feed Weibo share to:
