In December 1989, an outbreak of gastroenteritis associated with cake consumption occurred in a day-care center with 60 children and 12 staff in Saitama prefecture. Children were served cakes at the Christmas party held in the day-care center and ate them with their families. Thirty-three of the 59 children (56%), 16 of the 74 families (22%) and 1 of the 10 staff (10%) eating the cakes became ill. Illness consisted primarily of nausea, vomiting, diarrhea and fever; the median incubation period was 31 hours. Bacteriological analysis of stool specimens did not reveal a causative agent. Small round structured viruses (SRSV) were detected in fecal specimens from 10 of the 17 ill children (59%) and 2 of the 6 ill families (33%) by electron microscopy. Cakes were purchased from a bakery where an employee who prepared the cake denied symptoms, and SRSV was not detected in the fecal specimen from the employee. Thus, it was not determined that the cake was contaminated by a food handler.
1989年12月，埼玉县一家有60名儿童和12名工作人员的日托中心发生了一起与食用蛋糕相关的肠胃炎暴发事件。孩子们在日托中心举办的圣诞派对上食用了蛋糕，并与家人一起分享。食用蛋糕的59名儿童中有33名（56%）、74个家庭中有16个（22%）以及10名工作人员中有1名（10%）出现了发病症状。疾病主要表现为恶心、呕吐、腹泻和发热；中位潜伏期为31小时。粪便标本的细菌学分析未发现病原体。通过电子显微镜检查，在17名患病儿童中的10名（59%）以及6个患病家庭中的2个（33%）的粪便标本中检测到了小圆结构病毒（SRSV）。蛋糕是从一家面包店购买的，制作蛋糕的一名员工否认有症状，且在该员工的粪便标本中未检测到SRSV。因此，无法确定蛋糕是被食品处理人员污染的。
