The distribution and level of Campylobacter jejuni throughout broiler processing was evaluated. Six trials were conducted at three broiler processing plants to determine the occurrence of C. jejuni on commercial broilers as affected by specific processing functions. Counts were determined at specific sampling stations throughout the plants, and patterns of counts among sampling stations and plants were observed. Between 1,100 and 5,500 C. jejuni/1,000 cm2 skin surface (represents half the skin surface area of one defeathered broiler) were found on birds entering the three plants. Increases in C. jejuni levels were associated with both the picking and evisceration operations. Broiler carcasses ready for packaging contained approximately 50 organisms/1,000 cm2. Campylobacter jejuni was also recovered from gizzard samples, carcass and gizzard chill water, and swab samples taken of selected equipment surfaces.
对空肠弯曲菌在整个肉鸡加工过程中的分布和水平进行了评估。在三家肉鸡加工厂进行了六项试验，以确定特定加工环节对商品肉鸡空肠弯曲菌存在情况的影响。在工厂内特定的采样点进行计数，并观察采样点和工厂之间的计数模式。进入这三家工厂的肉鸡身上，每1000平方厘米皮肤表面（代表一只去毛肉鸡一半的皮肤表面积）发现有1100至5500个空肠弯曲菌。空肠弯曲菌数量的增加与抓鸡和开膛操作有关。准备包装的肉鸡胴体每1000平方厘米约含有50个菌。空肠弯曲菌还从砂囊样本、胴体和砂囊冷却水中以及选定设备表面的拭子样本中检出。
