1996年7月，日本大坂市Sakai市的学童中爆发了大肠杆菌O157：H7感染。这次爆发发生在该市13所东北区和34所中南区小学。7月17日至19日住院的所有儿童均于7月8日（东北区）和7月9日（中南区）就诊。7月1日和8日在东北区和7月1日，4日，8日和9日在中南区供应的学校午餐被一项食物消费研究提出与感染有关。在两个学区中，同一个农场的白色萝卜苗是7月8日东北区和7月9日中南区涉及最高的膳食中唯一常见的未煮熟的食物（7月8日的糖醋鸡生菜和7月9日的冷冻日本面条）。两起E.大肠杆菌O157：H7也与产地的白色萝卜苗有关。两地区及邻近地区患者分离株的脉冲场凝胶电泳图谱完全一致。因此，结论是爆发的原因是7月7日至9日从一个特定农场运来的白色萝卜苗。
In July 1996, an outbreak of Escherichia coli O157:H7 infection occurred among schoolchildren in Sakai City, Osaka, Japan. This outbreak developed in 13 North-East District and 34 Middle-South District elementary schools in the city. All children hospitalized on July 17-19 had presented on July 8 (North-East District) and July 9 (Middle-South District). School lunches served on July 1 and 8 in the North-East District and on July 1, 4, 8, and 9 in the Middle-South District were proposed by a food consumption study to be associated with infection. White radish sprouts from a single farm were the only uncooked food common to the most highly implicated meals on the involved days in two school districts (sweet and sour chicken with lettuce on July 8 in the North-East District and chilled Japanese noodles on July 9 in the Middle-South District). Two incidents of E. coli O157:H7 in neighboring areas were also related to white radish sprouts from the farm. The pulse-field gel electrophoresis patterns of isolates from patients in these two districts and the neighboring areas were identical. Thus, it was concluded that the cause of the outbreak was the white radish sprouts shipped on July 7-9 from one particular farm.
