A total of 882 samples of settled sewage, sewage sludges and final effluents from eight sewage treatment plants were examined for the presence of salmonellas. Of these samples 68% were positive, isolations being made most frequently from settled sewage (85%), raw sludge (87%) and anaerobically digested sludge (96%). Fewer isolations were made from final effluent (24%) and processed sludges (58%). Samples usually contained less than 200 salmonellas/100 ml and arguments are presented that such concentrations should not lead to disease in animals if suitable grazing restrictions are followed.
对来自8个污水处理厂的882份沉淀污水、污泥和最终出水样本进行了沙门氏菌检测。这些样本中,68%呈阳性,其中沉淀污水(85%)、生污泥(87%)和厌氧消化污泥(96%)中分离出沙门氏菌的频率最高。最终出水(24%)和处理后的污泥(58%)中分离出的沙门氏菌较少。样本中沙门氏菌的含量通常低于200个/100毫升,并且有观点认为,如果遵循适当的放牧限制,这样的浓度不会导致动物发病。
