Samples of milk from 1501 cows with mastitis were negative for Campylobacter jejuni. The faeces of 74 healthy Friesian cows were screened for C. jejuni: 13% of the samples were positive during the summer when the cows were on pasture, and 51% were positive in the winter when the cows were housed. Positive samples contained on average 1 X 10(4) campylobacters per g faeces. It is concluded that faecal contamination rather than udder infection is the means by which campylobacters enter milk and thereby infect man.
对1501头患乳腺炎奶牛的牛奶样本进行检测，空肠弯曲菌呈阴性。对74头健康弗里斯兰奶牛的粪便进行空肠弯曲菌筛查：夏季奶牛在牧场放牧时，13%的样本呈阳性；冬季奶牛圈养时，51%的样本呈阳性。阳性样本每克粪便平均含有1×10⁴个弯曲杆菌。研究得出结论，弯曲杆菌进入牛奶进而感染人类的途径是粪便污染而非乳房感染。
