A public swimming beach in Madison, wis., experienced intermittent high fecal coliform counts during the late summer and early fall of 1978. Public health officials closed the beach on a number of occasions. A public health survey identified a combination of waterfowl wastes and meteorological events as the explanation for the high bacteria counts. Fecal coliform bacteria were deposited by mallard ducks and multiplied in the beach sands. The bacteria were subsequently transported into the lake and resulted in high fecal coliform counts in the swimming area.
威斯康星州麦迪逊市的一个公共游泳海滩在1978年夏末和初秋期间,粪便大肠菌群计数间歇性偏高。公共卫生官员多次关闭该海滩。一项公共卫生调查确定,水禽粪便和气象事件共同导致了细菌计数偏高。绿头鸭排放了粪便大肠菌群细菌,这些细菌在海滩沙子中繁殖。随后,这些细菌被冲入湖中,导致游泳区域的粪便大肠菌群计数偏高。
