The bacteriological quality of beef and pig carcasses was assessed at 9 Norwegian abattoirs by sampling 10 carcasses at multiple sites on each of several visits. On beef carcasses the following sites consistently carried higher numbers of bacteria: the Brisket, the Fore-ribs, the Flank groin, and the Round medial. There was no evidence that beef slaughter and dressing in the hanging position was superior to methods where the carcass was lying until the hide puller. On pork carcasses the Cheek, and the Abdomen lateral surface (belly) were most heavily contaminated. The hygienic quality of pork carcasses in abattoirs where singeing was a separate step tended to be better than where a combined singeing and dehairing machine was used. This survey suggests that bacteriological monitoring of slaughter at this level of sampling and visiting is able to detect consistently poor hygienic practices. Where direct comparisons with data from other countries could be made, the present investigation indicates that the bacterial counts on Norwegian beef and pork carcasses are of the same order or better.
通过多次访问时在挪威9家屠宰场的多个部位对10头牛和猪的胴体进行采样，评估了牛肉和猪胴体的细菌学质量。在牛胴体上，以下部位的细菌数量始终较多：胸部、前肋骨、腹股沟和后腿内侧。没有证据表明牛在悬挂状态下屠宰和修整比在胴体躺卧直到剥皮机操作时的方法更优越。在猪胴体上，脸颊和腹部外侧（肚皮）污染最严重。在燎毛作为一个单独步骤的屠宰场，猪胴体的卫生质量往往比使用燎毛脱毛一体机的屠宰场更好。这项调查表明，在这种采样和访问水平下对屠宰进行细菌学监测能够持续检测出不良的卫生操作。在可以与其他国家的数据进行直接比较的情况下，本次调查表明挪威牛肉和猪胴体上的细菌计数处于同一水平或更好。
