This study compared the current pig slaughter procedure where the pluck set is completely removed with a procedure where the pluck set is partially removed, leaving the highly contaminated oral cavity, tonsils and tongue untouched. The effect on carcass contamination was investigated by enumerating hygiene indicator bacteria (total aerobic count, Enterobacteriaceae and E. coli) and cefotaxime-resistant E. coli (CREC) as well as assessing Salmonella and Yersinia enterocolitica presence on the sternum, elbow and throat of pig carcasses. Using the alternative pluck set removal, significantly lower mean numbers of hygiene indicator bacteria on throat samples and E. coli on elbow samples were found. Less pig carcasses were highly contaminated and a lower presence and level of CREC was observed. No difference in Salmonella or Yersinia enterocolitica presence was seen. The data in this study can help to assess the effect of this alternative procedure on the safety of pork and subsequently public health.

这项研究比较了目前的生猪屠宰程序，其中完全去除了拔毛套件，而部分去除了拔毛套件，使高度污染的口腔，扁桃体和舌头保持不变。通过列举卫生指示剂细菌（总需氧量，肠杆菌科和大肠杆菌）和耐头孢噻肟的大肠杆菌（CREC），并评估沙门氏菌和耶尔森氏菌肠球菌在胸骨，肘部和喉部的存在，研究了对car体污染的影响。猪的尸体。使用替代的采摘套件去除方法，可大大降低喉咙样品和大肠杆菌中卫生指示剂细菌的平均数量在肘上发现了样本。较少的猪pig体受到高度污染，并且观察到的CREC含量和水平较低。沙门氏菌或小肠结肠炎耶尔森氏菌的存在无差异。这项研究中的数据可以帮助评估该替代程序对猪肉安全以及随后的公共卫生的影响。
