Several sites on commercial beef, pork and lamb carcasses were sampled at the end of the slaughterline. Total viable counts (TVC) of bacteria were assessed by incubation at 37, 20 and 1 degree C in addition to presumptive coliforms (PC), Enterobacteriaceae (ENT) and faecal streptococci (FS). Statistical analyses showed consistently dirty sites within an abattoir but these sites varied from one abattoir to another. Inter-site differences were unaffected by the incubation temperature of the TVC. Numbers of PC, ENT and FS did not mimic TVC. Empirical sampling plans are proposed to detect the highest count on a carcass by bulking samples from known dirty sites. At the end of the slaughterline TVC 37 degrees C is the most useful bacteriological index.
在屠宰线末端对商业牛肉、猪肉和羊肉胴体的多个部位进行了采样。除了对推定大肠菌群（PC）、肠杆菌科（ENT）和粪链球菌（FS）进行检测外，还通过在37℃、20℃和1℃下培养来评估细菌的总活菌数（TVC）。统计分析表明，屠宰场内存在始终脏污的部位，但这些部位在不同屠宰场之间有所不同。TVC的培养温度对不同部位之间的差异没有影响。PC、ENT和FS的数量与TVC并不相似。建议采用经验性采样计划，通过将来自已知脏污部位的样本合并来检测胴体上的最高菌数。在屠宰线末端，37℃时的TVC是最有用的细菌学指标。
