在火鸡胴体加工和火鸡产品（香肠、火腿和去骨鸡胸肉）的进一步加工过程中，确定了不同位置存在空肠弯曲菌。火鸡尸体被C.空肠大多数发生在皮肤表面或腹腔衬里表面。未观察到内部肌肉组织污染。C.空肠在进入加工厂后的变化（50 - 100%）。大量的C。空肠在尸体的烫伤过程中被杀死，但在机械拔毛过程中发生了广泛的再污染。烫漂后，C.空肠在取出内脏时达到最高，但在清洗后降至较低水平。很少或没有C。在离开冷却槽后从尸体中回收空肠。没有C在批发或零售层面的冷冻火鸡屠体（包括滴注）上检测到空肠。然而，在批发水平冷冻储存2周和3个月的少数屠体的滴液中检测到大肠弯曲杆菌。也不是C。jejuni和C.在零售层面的冻火鸡中发现大肠杆菌。虽然在某些情况下，C。在进一步加工的初始阶段，从火鸡肉中回收空肠，没有C.从热处理的、进一步加工的产品中回收空肠。
Presence of Campylobacter jejuni was determined at various locations in turkey carcass processing and further processing of turkey products (wieners, ham and boneless breast). Contamination of turkey carcasses with C. jejuni, in most cases, occurred on the surface of the skin or on the surface of the abdominal cavity lining. No contamination of interior muscle tissue was observed. The percentage of turkeys containing C. jejuni upon entering the processing plant varied (50 to 100%). Large numbers of C. jejuni were killed during scalding of carcasses, but extensive recontamination occurred during mechanical defeathering. After scalding, numbers of C. jejuni peaked during evisceration, but dropped to lower levels after wahing. Few or no C. jejuni were recovered from the carcasses after leaving the chill tank. No C. jejuni were detected on frozen turkey carcasses, including the drip, at the wholesale or retail level. However, Campylobacter coli was detected in the drip of a few carcasses that had been in frozen storage at the wholesale level for 2 wk and 3 months. Neither C. jejuni nor C. coli was detected on frozen turkeys at the retail level. Although, in some cases, C. jejuni were recovered from turkey meat during initial stages of further processing, no C. jejuni were recovered from heat-treated, further processed products.
