从1998年4月至2000年3月，18个肉鸡群从孵化场到屠宰场进行了跟踪。在孵化场、1日龄雏鸡和雏鸡到达前的饲养室中未发现弯曲杆菌。肉鸡群感染率在饲养期间不断上升，至饲养结束时共有7个阳性鸡群。具有弯曲杆菌阳性肉鸡的农场的特征在于弯曲杆菌在环境（水坑、粪堆）和农民的鞋上的循环。抗生素的管理并没有显着减少弯曲杆菌脱落。除饲养期间的一个鸡群和屠宰场中的几个鸡群有结肠弯曲杆菌和空肠弯曲杆菌混合感染外，C。在饲养期间和尸体上均发现空肠。肉鸡饲养过程中的污染与加工后的胴体质量之间存在显著的相关性。没有一个屠宰场能够在运送状态呈阳性的动物时避免污染尸体。此外，6个阴性交付的鸡群产生了阳性尸体，这是运输和屠宰过程中发生的补充污染的结果。
From April 1998 to March 2000, 18 broiler flocks were followed from the hatchery to the slaughterhouse. Campylobacter was not found in the hatchery, 1-day-old chicks or in the rearing house before the arrival of the chicks. The infection of broiler flocks increased continuously during the rearing time, with a total of seven positive flocks at the end of rearing. Farms with Campylbacter-positive broilers were characterized by the circulation of Campylobacter in the environment (puddles, dung hill) and on the footwear of the farmer. The administration of antibiotics did not significantly reduce Campylobacter shedding. With the exception of one flock during rearing and a few flocks in the slaughterhouse with a mixed Campylobacter coli Campylobacter jejuni infection, C. jejuni exclusively was found both during rearing and on the carcasses. A significant correlation exits between the contamination of the broilers during rearing and the carcasses after processing. No slaughterhouse was able to avoid contamination of carcasses when status-positive animals were delivered. Moreover, six negatively delivered flocks yielded positive carcasses, the result of a supplementary contamination, which occurred during transport and slaughtering.
