英国疯牛病造成了人类疾病传播的潜在危害,牛羊肉等肉食品的安全备受关注。为了避免疯牛病污染的肉品进入食物链,世界多个研究小组对各类肉食品开展了基于疯牛病传播因子安全方面的研究。疯牛病患病牛肉可以直接感染人类并导致发病,阳性病牛应彻底销毁并进行无害化处理,严禁进入食物链。染病的羊肉和鹿肉属于高度危险食品,也应做销毁处理,而猪肉、马肉、兔肉和水牛肉等则相对比较安全。同时,朊蛋白疾病的感染还与人类自身朊蛋白编码基因多态性有关。在严格检疫的同时,培育抗病品种的家畜以及食用不易感的肉类食品成为未来肉食品安全的一种发展趋势。本文总结了疯牛病、痒病等可传播海绵状脑病患病动物的肉用安全性,还分析了疯牛病可能突破种间屏障而造成跨物种传播的可能性,为肉食品安全及检疫提供参考。
The mad cow disease in the United Kingdom has caused the potential harm of the spread of human diseases. The safety of beef, mutton and other meat products has drawn much attention. In order to avoid the mad cow disease contamination of meat products into the food chain, the world’s many research groups for all types of meat products based on the BSE safety factor studies. Bovine mad cow disease The beef can directly infect humans and lead to the disease, the positive cow should be completely destroyed and detoxified, non-access to the food chain. Infected mutton and venison are highly dangerous foods and should be disposed of, while pork, horse meat, rabbit meat and buffalo meat are relatively safe. At the same time, prion disease infection is also associated with human prion protein coding gene polymorphism. In the strict quarantine at the same time, cultivate disease-resistant breeds of livestock and meat is not easy to eat food as a future trend of meat safety. This article summarizes the safety of the animals that can transmit spongiform encephalopathy (BSE), such as mad cow disease and itch disease, and analyzes the possibility that BSE may break the barrier between species and cause cross-species spread and provide reference for meat food safety and quarantine.
