An outbreak of gastroenteritis in a school district in the United States was determined to be staphylococcal food poisoning due to 2% chocolate milk containing staphylococcal enterotoxin A (SEA). Twelve one-half pint (approx 0.28 l) cartons of the 2% chocolate milk from this outbreak were analyzed for the quantity of SEA present in the milk. The amount of SEA in the cartons varied from 94 to 184 ng with the average being 144 ng (mean = 139 +/- 45). The attack rate for vomiting among those who consumed more than one carton was greater (38.3%) than among those who consumed only one carton (31.5%) with the highest attack rate among those who consumed three or more cartons (44.4%).
美国一个学区爆发的肠胃炎被认定为是由含有葡萄球菌肠毒素A（SEA）的2%巧克力牛奶导致的葡萄球菌食物中毒。对此次疫情中涉及的12盒半品脱（约0.28升）的2%巧克力牛奶进行了分析，以确定牛奶中SEA的含量。这些牛奶盒中SEA的含量在94至184纳克之间，平均为144纳克（均值 = 139 +/- 45）。饮用超过一盒牛奶的人群中呕吐的发病率（38.3%）高于仅饮用一盒牛奶的人群（31.5%），饮用三盒或更多盒牛奶的人群中呕吐发病率最高（44.4%）。
