In Denmark, the incidence of human campylobacteriosis cases, as well as the Campylobacter prevalence in broiler flocks, is strongly influenced by season with a summer peak in July-August. Therefore, it was considered that the prevalence of Campylobacter in broiler meat sold at retail in Denmark might also be influenced by season. A retrospective survey analysis was performed on 2001-2007 national surveillance data of the prevalence of thermotolerant Campylobacter in all conventional broiler flocks at slaughter, and in randomly sampled broiler meat at retail. There was a significant effect of season on the occurrence of Campylobacter in meat at retail; the largest effect was found for domestic chilled meat. Thus, the Campylobacter prevalence in Danish broiler flocks, which fluctuated with season, was found to be a strong predictor for the occurrence of Campylobacter in fresh, chilled, Danish broiler meat. However, besides flock prevalence, there was also a direct effect of season on the occurrence of Campylobacter in Danish broiler meat at retail.
在丹麦，人类弯曲菌病病例的发病率以及肉鸡群中弯曲菌的流行率受季节影响很大，夏季 7 月至 8 月达到高峰。因此，人们认为丹麦零售销售的肉鸡肉中弯曲菌的流行率也可能受到季节的影响。对 2001 年至 2007 年全国监测数据进行了回顾性调查分析，监测内容包括屠宰时所有常规肉鸡群中耐热弯曲菌的流行率，以及零售时随机抽取的肉鸡肉中耐热弯曲菌的流行率。零售肉中弯曲菌的发生与季节有关，这一现象有显著影响；国内冷藏肉受到的影响最大。因此，丹麦肉鸡群中随季节波动的弯曲菌流行率是导致新鲜、冷藏丹麦肉鸡肉中弯曲菌发生的一个强有力的预测因素。然而，除了鸡群流行率外，季节对丹麦零售肉鸡肉中弯曲菌的发生也有直接影响。
