Two federally inspected California chicken processing plants participated in Campylobacter jejuni prevalence studies. Twelve sampling sites were included in each of four groups. Groups were based on bird age, scald water temperature, and plant sampled. Scald water temperatures of 60 degrees C (140 degrees F) did not contribute to a lower prevalence of C. jejuni in edible parts, as did temperatures of 53 degrees C (127 degrees F) and 49 degrees C (120 degrees F). The feather picker and chilling tank were areas of major cross-contamination. C. jejuni was isolated from 68% of the ready-for-market products. The organism was recovered from 60 to 100% of the ceca in the four groups, and some numbers in the fecal material exceeded 10(6)/g. The level of C. jejuni in intestinal tracts seemed to correlate with the presence of the organism in the edible parts.
两家接受联邦检查的加利福尼亚鸡肉加工厂参与了空肠弯曲菌流行率研究。四个组中的每组都包含12个采样点。分组基于鸡龄、烫毛水温以及所采样的工厂。60摄氏度(140华氏度)的烫毛水温与53摄氏度(127华氏度)和49摄氏度(120华氏度)的水温一样,都不会使可食用部分的空肠弯曲菌流行率降低。拔毛机和冷却槽是主要的交叉污染区域。从68%的待上市产品中分离出了空肠弯曲菌。在四组中,从60%至100%的盲肠中检出了该菌,并且粪便中的一些菌数超过了10⁶/g。肠道中空肠弯曲菌的水平似乎与可食用部分中该菌的存在相关。
