A baseline survey on the prevalence of Campylobacter spp. in broiler flocks and Campylobacter spp. on broiler carcases in the UK was performed in 2008 in accordance with Commission Decision 2007/516/EC. Pooled caecal contents from each randomly selected slaughter batch, and neck and breast skin from a single carcase were examined for Campylobacter spp. The prevalence of Campylobacter in the caeca of broiler batches was 75·8% (303/400) compared to 87·3% (349/400) on broiler carcases. Overall, 27·3% of the carcases were found to be highly contaminated with Campylobacter (≥1000 c.f.u./g). Slaughter in the summer months (June, July, August) [odds ratio (OR) 3·50], previous partial depopulation of the flock (OR 3·37), and an increased mortality at 14 days (≥1·25% to <1·75%) (OR 2·54) were identified as significant risk factors for the most heavily Campylobacter-contaminated carcases. Four poultry companies and farm location were also found to be significantly associated with highly contaminated carcases.
2008 年，英国按照欧盟委员会第 2007/516/EC 号决定，对肉鸡群中弯曲杆菌属的流行情况以及鸡只屠体中的弯曲杆菌属进行了基线调查。对每个随机选择的屠宰批次的盲肠内容物以及单个屠体的颈部和胸部皮肤进行了弯曲杆菌属检测。与屠体相比，肉鸡批次盲肠中弯曲杆菌的流行率为 75.8%（303/400），而 87.3%（349/400）。总体而言，27.3%的屠体被高度污染弯曲杆菌（≥1000 c.f.u./g）。夏季（6、7、8 月）屠宰（比值比（OR）3.50）、之前部分清群（OR 3.37）以及 14 日死亡率增加（≥1.25%至<1.75%）（OR 2.54）被确定为弯曲杆菌污染最严重屠体的显著风险因素。还发现四个家禽公司和农场位置与高度污染的屠体显著相关。
