An epidemiological study was conducted to estimate the prevalence of Salmonella spp. contamination in French commercial breeding and fattening turkey flocks at the end of the rearing period, as part of a European Union-wide baseline study. Two hundred and five breeding turkey flocks and three hundred and two fattening turkey flocks were included in the study, between October 2006 and September 2007. The Salmonella status of flocks was assessed by collecting five environmental faeces samples, analysed by classical bacteriological method. The prevalence of Salmonella positive flocks was 1.5% for breeding turkeys and 15.6% (95% CI: 11.5; 19.7) for fattening turkeys. Information on potential risk factors of the turkey flock being Salmonella positive was collected by questionnaire at the same time as sample collection. The association between management practices, general hygiene and Salmonella status in French turkey flocks was assessed by logistic regression. The risk of Salmonella contamination in fattening turkey flocks was decreased when floors were disinfected during decontamination procedures, when Salmonella detection was carried out during rearing and when there was a metering pump in the house. However in this study, the risk was increased when the farmer used a footbath at the turkey house entrance. Risk factors for Salmonella in breeding turkey flocks could not be subjected to formal statistical analysis since only three flocks were contaminated.
一项流行病学研究旨在估计法国商业养殖和育肥火鸡群在饲养期末沙门氏菌污染的流行率，这是欧盟范围内基线研究的一部分。2006 年 10 月至 2007 年 9 月期间，共纳入 205 个繁殖火鸡群和 302 个育肥火鸡群。通过收集五个环境粪便样本并通过经典细菌学方法进行分析来评估鸡群的沙门氏菌状况。繁殖火鸡群中沙门氏菌阳性鸡群的流行率为 1.5%，育肥火鸡群为 15.6%（95%CI：11.5; 19.7）。在收集样本的同时，通过问卷调查收集了有关火鸡群可能成为沙门氏菌阳性的风险因素的信息。通过逻辑回归评估了法国火鸡群的管理实践、一般卫生状况和沙门氏菌状况之间的关系。在育肥火鸡群中，地板在消毒过程中进行消毒、在饲养期间进行沙门氏菌检测以及房屋中有计量泵时，火鸡群污染沙门氏菌的风险降低。然而，在这项研究中，当农民在火鸡舍入口处使用洗脚盆时，风险会增加。由于只有三个鸡群受到污染，因此无法对繁殖火鸡群中沙门氏菌的风险因素进行正式的统计分析。
