A food-borne outbreak of pharyngitis from group A streptococcus developed in people attending wedding banquets in the same restaurant on July 5-8, 1986. Of the 300 people interviewed, 179 reported illness; pharyngeal swabs were taken from 115 ill people; from 63 (53%) of them group A streptococci, belonging to serotype T28, M28, were isolated. Statistical analysis performed using chi-square and Cochran's test showed that a prawn hors-d'oeuvre served on July 5 and squills or/and custard cake served on July 7 could have been a possible source of infection. Six people on the staff, 5 of whom belonged to the family of the restaurant manager, and the manager's three young daughters were colonized by the same group A serotype. A possible previous diffusion of the strain among the staff followed by contamination of the food was suspected.
1986年7月5日至8日，在同一家餐厅参加婚宴的人群中发生了一起由A组链球菌引起的食源性咽炎暴发。在接受采访的300人中，179人报告患病；从115名患病者中采集了咽拭子；其中63人（53%）分离出属于T28、M28血清型的A组链球菌。使用卡方检验和 Cochr an检验进行的统计分析表明，7月5日供应的开胃虾以及7月7日供应的海葱或/和蛋奶酥蛋糕可能是感染源。餐厅6名工作人员中，有5人属于餐厅经理的家人，经理的3个小女儿也被同一A组血清型定植。怀疑该菌株先前可能在工作人员中传播，随后污染了食物。
