Roof-collected rainwater is a common water source in subtropical regions and has not been associated with human illness. In Trinidad, the West Indies, a church group, attending a rural camp, developed gastrointestinal illness, caused by Salmonella arechevalata. This rare serotype was isolated from stool specimens of campers, foods eaten at the camp, and a water tap, which was supplied by a storage tank of roof-collected rainwater. The surface of the roof, used as water catchment, was covered with bird faeces. It is postulated that rainwater, falling on the roof, washed off animal excrement which contained S. arechevalata and led to the outbreak of salmonellosis through camper ingestion of contaminated food and water.
屋顶收集的雨水是亚热带地区常见的水源，且与人类疾病无关。在西印度群岛的特立尼达，一个参加乡村营地活动的教会团体出现了由阿氏沙门氏菌引起的胃肠道疾病。从露营者的粪便样本、营地食用的食物以及一个由屋顶收集雨水的储水箱供水的水龙头中分离出了这种罕见的血清型。用作集水区的屋顶表面覆盖着鸟粪。据推测，落在屋顶上的雨水冲走了含有阿氏沙门氏菌的动物粪便，并通过露营者摄入受污染的食物和水导致了沙门氏菌病的爆发。
