The aim was to compare the effects of two evisceration methods under operational conditions, on the pelvic hygiene of sheep carcasses. Method 1: rectum sealed with plastic bag and pushed through the pelvic cavity. Method 2: rectum cut, placed back inside and pulled out from the carcass. The 18 largest Norwegian sheep abattoirs participated. Sampling areas were i) 400 cm² inside the pelvic cavity (n = 623), ii) 100 cm² outside the circum-anal incision (n = 622). There were pooled samples by swabbing the same area of five carcasses, representing totally 3115 carcasses. Mean E. coli results from Method 1: − 1.61 log CFU/cm² inside and − 0.25 log CFU/cm² for the outside area. Results from Method 2: − 1.56 log CFU/cm² inside and − 0.42 log CFU/cm² outside. There were no significant differences between the two methods. Both evisceration methods can produce carcasses that are of practically identical high hygienic quality.

目的是比较两种剔除方法在操作条件下对绵羊car体骨盆卫生的影响。方法1：用塑料袋将直肠密封并推入骨盆腔。方法2：将直肠切开，放回内部并从the体中拉出。挪威最大的18个绵羊屠场参加了比赛。取样区域为：i）骨盆腔内400 cm ²（n = 623），ii）肛周切口外100 cm ²（n = 622）。通过擦拭相同区域的5个屠体来收集样品，总共代表3115个屠体。方法1产生的平均大肠杆菌数：-内部1.61 log CFU / cm ²和-0.25 log CFU / cm ²对于外部区域。方法2的结果：-内部为1.56 log CFU / cm ^2，外部为-0.42 log CFU / cm ²。两种方法之间没有显着差异。两种去内脏方法都可以生产出几乎相同的高卫生质量的car体。
