Ante- and post-mortem inspections at abattoir were originally introduced to provide assurance that animal carcasses were fit for human consumption. However, findings at meat inspection can also represent a valuable source of information for animal health and welfare surveillance. Yet, before making secondary use of meat inspection data, it is important to assess that the same post-mortem findings get registered in a consistent way among official meat inspectors across abattoirs, so that the results are as much independent as possible from the abattoir where the inspection is performed. The most frequent findings at official meat inspections of pigs and beef cattle in Sweden were evaluated by means of variance partitioning to quantify the amount of variation in the probabilities of these findings due to abattoir and farm levels. Seven years of data (2012-2018) from 19 abattoirs were included in the study. The results showed that there was a very low variation between abattoirs for presence of liver parasites and abscesses, moderately low variation for pneumonia and greatest variation for injuries and nonspecific findings (e.g., ). This general pattern of variation was similar for both species and implies that some post-mortem findings are consistently detected and so are a valuable source of epidemiological information for surveillance purposes. However, for those findings associated with higher variation, calibration and training activities of meat inspection staff are necessary to enable correct conclusions about the occurrence of pathological findings and for producers to experience an equivalent likelihood of deduction in payment (independent of abattoir).
屠宰场的宰前和宰后检查最初是为了确保动物胴体适合人类食用。然而，肉类检查的结果也可能是动物健康和福利监测的宝贵信息来源。但是，在二次使用肉类检查数据之前，重要的是要评估在各屠宰场的官方肉类检查员之间，相同的宰后检查结果是否以一致的方式进行记录，以便结果尽可能独立于进行检查的屠宰场。通过方差分解对瑞典官方对猪和肉牛检查中最常见的结果进行评估，以量化这些结果的概率因屠宰场和农场层面而产生的变化量。该研究纳入了19个屠宰场的七年数据（2012 - 2018年）。结果表明，肝脏寄生虫和脓肿的存在在各屠宰场之间的差异非常小，肺炎的差异适中，而损伤和非特异性发现（如……）的差异最大。这种总体差异模式在两个物种中相似，这意味着一些宰后检查结果能够持续被检测到，因此是用于监测目的的有价值的流行病学信息来源。然而，对于那些差异较大的结果，有必要对肉类检查人员进行校准和培训活动，以便就病理结果的发生得出正确结论，并使生产者经历相同的付款扣除可能性（与屠宰场无关）。
