Cecal cultures taken over a 1-year period from 600 turkeys at a poultry processing plant were all positive for Campylobacter fetus subsp. jejuni. Swabs of the cloaca and fresh feces were likewise all positive. Of 33 freshly dressed turkey carcases, 94% were positive before chilling in tanks of chlorinated ice and water; 34% of 83 carcasses were still positive after overnight soaking in the tanks. Increasing the chlorine content from 50 to 340 ppm (50 to 340 micrograms/ml) did not cause a decrease in the number of positive carcasses. C. fetus subsp. jejuni was isolated from wastewater gutters as well as from chutes and conveyor belts in the packaging room. Water samples from the five water treatment lagoons for the plant were all positive for C. fetus subsp. jejuni while the plant was in operation, but 4 days after the plant closed for the winter, all water samples were negative.
在一家家禽加工厂，对600只火鸡在1年时间内采集的盲肠培养物，空肠弯曲菌胎儿亚种检测结果均为阳性。泄殖腔拭子和新鲜粪便检测结果同样均为阳性。在33只刚屠宰的火鸡胴体中，94%在放入加氯冰水槽冷却前检测呈阳性；在水槽中浸泡过夜后，83只胴体中有34%仍呈阳性。将氯含量从50 ppm（50微克/毫升）提高到340 ppm（340微克/毫升），并未使阳性胴体数量减少。空肠弯曲菌胎儿亚种不仅从废水水槽中分离出来，还从包装车间的滑道和传送带上分离出来。工厂五个水处理泻湖的水样在工厂运营期间空肠弯曲菌胎儿亚种检测结果均为阳性，但在工厂冬季关闭4天后，所有水样检测均为阴性。
