Following a private party in Río Piedras, PR, 23 (56 percent) of those who attended developed an illness characterized by pharyngitis, myalgia, fatigue, headache, and fever. Consumption of carrucho (conch) salad was significantly associated with illness (P = 0.013, Fisher's exact test). Group A beta-hemolytic streptococci (M nontypable T12, serum opacity factor positive) were isolated both from throat cultures in 11 of 47 persons who attended the party and from the implicated food. The original source of contamination of the conch salad was not identified. Because complications may still occur from such infections and only a small percentage of persons with sore throats seek medical attention and ultimately receive treatment for their illnesses, it is important to recognize these outbreaks.
在波多黎各里奥彼德拉斯的一次私人聚会上，参加聚会的人中有23人（56%）出现了以咽炎、肌痛、疲劳、头痛和发热为特征的疾病。食用海螺沙拉与疾病显著相关（P = 0.013，Fisher精确检验）。在参加聚会的47人中，有11人的咽喉培养物以及涉事食物中均分离出A组β溶血性链球菌（M不可分型T12，血清混浊因子阳性）。海螺沙拉的最初污染源未查明。由于此类感染仍可能引发并发症，而且只有一小部分喉咙痛的人会就医并最终接受疾病治疗，因此认识到这些疫情很重要。
