The contamination of cheese by Salmonella typhimurium serotype 10 resulted in the bacteriological examination of raw milk from 327 farms on Prince Edward Island. A milk sample from a bulk tank from one farm was positive for this pathogen. The possible source was linked to the isolation of the strain from the milk from one quarter of one cow. Although the cow was asymptomatic for any clinical illness other than a chronic staphylococcal mastitis in two quarters, the animal continued to shed Salmonella in the milk during a 36 day period. Necropsy failed to reveal a source of the infection.
鼠伤寒沙门氏菌10型对奶酪的污染导致了对爱德华王子岛327个农场的原料奶进行细菌学检查。来自一个农场的一个奶罐的一份奶样对这种病原体检测呈阳性。可能的源头与从一头奶牛一个乳区的奶中分离出该菌株有关。尽管这头奶牛除了两个乳区患有慢性葡萄球菌性乳腺炎外没有任何其他临床疾病的症状，但在36天的时间里，这头牛的奶中持续排出沙门氏菌。尸检未能发现感染源。
