Effluents from 12 sewage treatment plants in southern California were examined for Salmonella using a Moore swab technique. Eight of the 12 plants were positive for Salmonella when sampled at the chlorination/dechlorination site (inside the plant). Effluents from 11 of 12 sewage treatment plants were positive for Salmonella when samples were analyzed downstream of the chlorination/dechlorination site, before effluents merge with the receiving stream (outside the plant). Two of the three control sites, an urban runoff, a raw potable water reservoir, and two other sites were also positive for Salmonella. A total of 683 Salmonella isolations were represented by 11 serogroups and 54 serotypes from 26 of 32 sampling sites. Effluents from three treatment plants and one control site (raw potable water resevior) yielded Salmonella enteritidis phage type 4, in addition to other serotypes.
采用穆尔拭子技术对南加州12家污水处理厂的废水进行沙门氏菌检测。在12家工厂中，有8家在加氯/脱氯位点（工厂内部）采样时沙门氏菌呈阳性。在12家污水处理厂中，有11家的废水在加氯/脱氯位点下游、废水与接纳溪流合并之前（工厂外部）进行分析时沙门氏菌呈阳性。三个对照点中的两个，即城市径流、原饮用水水库以及另外两个位点的沙门氏菌检测也呈阳性。在32个采样点中的26个点共分离出683株沙门氏菌，分属于11个血清群和54个血清型。除其他血清型外，来自三家处理厂和一个对照点（原饮用水水库）的废水还检出了4型肠炎沙门氏菌噬菌体。
