上海某奶牛养殖专业合作社结核病的暴发调查

An investigation of tuberculosis outbreak at a dairy farm in Shanghai

上海市某奶牛养殖专业合作社检出14头结核病阳性牛。为查明疫病发生状况,调查疫病可能的发生原因,提出针对性的防控措施,通过现场座谈、问卷调查、实地查看和档案资料查阅等方式开展了暴发调查。结果发现本次暴发调查与奶牛引进有关,历年来检测发现的结核病阳性牛和疑似牛未采取有效的隔离、淘汰处置措施,从而导致了结核病的场内循环。建议立即扑杀和无害化处理结核病阳性牛,加强环境消毒,加大结核病监测频率和力度,同时做好工作人员的结核病健康检查。

14 Tuberculosis-inflicted cows were found in a dairy farm in Shanghai.In order to find out the causes of the outbreak of the epidemic,so as to put forward suggestions for prevention and control of the situation,an outbreak investigation was carried out through on-site discussion,questionnaires,field inspection and data checking.It was found that the outbreak of the tuberculosis cases was related to the introduction of cows,and in particular to the lack of effective isolation and elimination of tested positive and suspected cows,resulting in the field circulation of tuberculosis at the farm.It was suggested that immediate culling and harmless disposal of Tuberculosis positive cows,strengthening environmental disinfection,increasing the frequency and intensity of Tuberculosis testing were performed,and that physical examination of Tuberculosis for workers at the farm was necessary.
