This study examined the impact of key processing stages and flock variables on the prevalence of Campylobacter on broiler carcasses. Overall, the prevalence of Campylobacter was 62% in caeca, and 68%, 65% and 62% in neck skin samples collected after evisceration, final wash and carcass chilling, respectively. Campylobacter were found in 32% of caeca, and 52%, 40% and 32% of neck skin samples collected after evisceration, final wash and carcass chilling, respectively from first thin broiler batches. Final thin broiler batches were more frequently contaminated with prevalences of 83% found in caeca, 80% in neck skin samples collected after evisceration and 83% found in neck skin samples collected after both final wash and carcass chilling stages (p < 0.05). Thinning status had a significant effect on Campylobacter counts with significantly higher counts observed in samples from final thin batches (p < 0.05). Highest Campylobacter concentrations in neck skin samples were observed at the evisceration stage in both first and final thin samples, with counts ranging from 2.0 to 3.8 log₁₀ CFU/g and 2.3 to 4.8 log₁₀ CFU/g in first and final thin batches, respectively. All first thin samples had counts below the European Union (EU) Process Hygiene Criterion threshold level of 3 log₁₀ CFU/g after chilling while 52% of final thin batches had counts above this limit.

这项研究检查了关键加工阶段和鸡群变量对肉鸡弯曲杆菌患病率的影响。总体而言，弯曲杆菌的流行率在盲肠中为62％，在去内脏，最后清洗和cas体冷却后收集的颈部皮肤样本中分别为68％，65％和62％。弯曲杆菌分别从第一批薄肉鸡的内脏，最终洗净和car体冷却后的32％的盲肠，52％，40％和32％的颈部皮肤样本中发现了这些成分。最终的薄肉鸡批次受到更频繁的污染，在盲肠中的发现率为83％，在内脏后收集的颈部皮肤样本中发现率为80％，在最终清洗和stages体冷却阶段后收集的颈部皮肤样本中发现率为83％（p <0.05）。稀化状态对弯曲杆菌计数有显着影响，在最终稀薄批次的样品中观察到的计数显着更高（p <0.05）。在第一个和最后一个薄样本的去内脏阶段，在颈部皮肤样本中观察到最高弯曲杆菌浓度，计数范围从2.0到3.8 log ₁₀ CFU / g和2.3至4.8 log ₁₀  CFU / g分别在第一个和最后一个稀薄批次中。 冷藏后，所有第一批稀薄样品的计数均低于欧盟工艺卫生标准阈值水平，即3 log ₁₀ CFU / g，而最终稀薄批次中有52％的计数高于该限值。
