Campylobacter is one of the most commonly reported foodborne pathogens in the United States. Because poultry is considered a major source of Campylobacter infections in humans, reduction of Campylobacter contamination in poultry products is likely the most important and effective public health strategy for reducing the burden of campylobacteriosis in humans. A comprehensive on-line survey was conducted of key stakeholders in the U.S. broiler industry, including broiler farm managers (n = 18), poultry veterinarians (n = 18), and processing plant managers (n = 20), to assess the current pre- and postharvest Campylobacter interventions and control measures practiced by the industry for reducing Campylobacter contamination of broiler products. The survey also included information regarding each respondent's understanding of Campylobacter transmission and ecology in relation to broiler production. The results revealed that a majority of the establishments included in the survey are following the U.S. Department of Agriculture, Food Safety and Inspection Service guidelines for controlling Campylobacter contamination in broiler flocks and on carcasses. However, establishments appeared to be putting more effort into Salmonella control than into Campylobacter control both on the farm and in the processing plant. A majority of the respondents responded that current interventions are not effective for reducing Campylobacter contamination, especially on the farm. Many respondents did not understand the risk factors associated with Campylobacter colonization in broiler flocks and on carcasses. Continued educational and training programs for key stakeholders in the U.S. broiler industry are needed to increase awareness of the issues associated with Campylobacter infection in broiler chickens and of the fact that Campylobacter infection is a multifaceted problem that requires efforts from both the pre- and postharvest sectors.
弯曲杆菌是美国报告最多的食源性病原体之一。由于家禽被认为是人类弯曲杆菌感染的主要来源，减少家禽产品中的弯曲杆菌污染可能是减轻人类弯曲杆菌病负担的最重要且最有效的公共卫生策略。对美国肉鸡行业的关键利益相关者进行了一项全面的在线调查，其中包括肉鸡养殖场经理（18人）、家禽兽医（18人）和加工厂经理（20人），以评估该行业目前为减少肉鸡产品弯曲杆菌污染而采取的收获前和收获后弯曲杆菌干预措施及控制措施。该调查还包括有关每位受访者对与肉鸡生产相关的弯曲杆菌传播和生态的理解的信息。结果显示，参与调查的大多数企业都遵循美国农业部食品安全与检验局关于控制肉鸡群和胴体中弯曲杆菌污染的指南。然而，无论是在农场还是在加工厂，企业似乎在沙门氏菌控制方面投入的精力比弯曲杆菌控制方面更多。大多数受访者表示，目前的干预措施对于减少弯曲杆菌污染并不有效，尤其是在农场。许多受访者不了解与肉鸡群和胴体中弯曲杆菌定植相关的风险因素。需要为美国肉鸡行业的关键利益相关者持续开展教育和培训项目，以提高对与肉鸡弯曲杆菌感染相关问题的认识，以及认识到弯曲杆菌感染是一个多方面的问题，需要收获前和收获后部门共同努力。
