On 10 September 2001, the first case of bovine spongiform encephalopathy (BSE) in Japan was confirmed in a five-year-old dairy cow born in Hokkaido and raised in Chiba prefecture. Subsequently, BSE surveillance was enhanced. As a result, 35 additional cases were detected by the end of March 2009, with two to ten cases being detected each year up to the end of 2007. The epidemic appeared to peak in 2006. Cases are detected mostly in dairy cattle; in cattle born in 1996 and 2000; and in cattle born in Hokkaido. Two were atypical cases of BSE and the remainder classical cases. This paper describes and discusses the demographic structure of dairy and beef cattle, surveillance programmes in place and the epidemiological features of the BSE epidemic in Japan.
2001年9月10日，日本首例牛海绵状脑病（BSE）在一头出生于北海道、饲养于千叶县的5岁奶牛身上得到确诊。随后，BSE监测工作得到加强。结果，截至2009年3月底又检测出35例病例，到2007年底每年检测出2至10例病例。疫情似乎在2006年达到高峰。病例大多出现在奶牛身上；出生于1996年和2000年的牛；以及出生于北海道的牛。其中两例是非典型BSE病例，其余为经典病例。本文描述并讨论了奶牛和肉牛的种群结构、现有的监测计划以及日本BSE疫情的流行病学特征。
