Raw sewage sludge, containing up to 10(5) naturally occuring salmonellas/1, was included in the diet of one group of cattle at the rate 1 ]/animal/day and in a second group at the rate of 1 ]/animal/week. Sterilized sludge, to which had been added 10(5) S. dublin/litre, was included in the diet of a third group of animals at the rate of 1 ]/animal/day. Salmonellas were isolated from all samples of raw sewage sludge but were not isolated from the faeces or carcasses of animals fed on the sludge. Salmonellas were isolated from the faeces of one animal and the carcasses of two animals fed on sterilized sludge to which S. dublin had been added.
含有高达每升10⁵个天然存在的沙门氏菌的未经处理的污水污泥，以每头动物每天1升的量添加到一组牛的日粮中，另一组则以每头动物每周1升的量添加。向经过灭菌的污泥中添加每升10⁵个都柏林沙门氏菌后，以每头动物每天1升的量添加到第三组动物的日粮中。从所有未经处理的污水污泥样本中都分离出了沙门氏菌，但在食用该污泥的动物的粪便或尸体中未分离出沙门氏菌。在食用添加了都柏林沙门氏菌的灭菌污泥的一头动物的粪便和两头动物的尸体中分离出了沙门氏菌。
