This article evaluates different aspects of meat inspection that are important in an integrated quality control system for slaughter pigs. The meat inspection service registers post-mortem abnormalities. However, to achieve a reliable registration, it is necessary to be able to identify individual animals on the slaughter-line. The information about post-mortem abnormalities can be used by the meat inspection service. Percentages of abnormalities in a shipment of pigs were included in meat inspection indices. It was not possible to predict the percentages of abnormalities in shipment of pigs from individual pig suppliers, but it was possible to classify fattening herds according to the meat inspection index. Information about the pigs delivered from a fattening herd was provided in two ways: by delivering relevant information on a quality control card, and by preselecting (done by the pig supplier) pigs according to the presence or absence of abnormalities. With both methods it was possible to divide pigs into a group with and a group without post-mortem abnormalities. It is necessary that the information supplied is accurate. Information can be checked by screening a number of animals for drug residues (and zoonoses) at the slaughterhouse, and by checking the information registered by the pig supplier in logbooks kept on the farm. From a comparison of results obtained with a meat inspection method based on visual inspection (no incisions, no palpitation) of the carcass with those obtained with the regular meat inspection method, it can be concluded that many abnormalities are detected equally well with both methods. Some recommendations for further research are given.
本文评估了生猪综合质量控制体系中肉类检验的不同重要方面。肉类检验服务机构记录宰后异常情况。然而，为了实现可靠的记录，必须能够在屠宰线上识别每头动物。肉类检验服务机构可以利用有关宰后异常情况的信息。一批生猪中的异常百分比被纳入肉类检验指标。无法根据单个生猪供应商提供的生猪预测一批生猪中的异常百分比，但可以根据肉类检验指标对育肥猪群进行分类。来自育肥猪群的生猪信息通过两种方式提供：在质量控制卡上提供相关信息，以及由生猪供应商根据是否存在异常情况预先挑选生猪。通过这两种方法都可以将生猪分为有宰后异常和无宰后异常两组。所提供的信息必须准确。可以通过在屠宰场对一些动物进行药物残留（和人畜共患病）筛查，以及检查生猪供应商在农场保存的日志中登记的信息来核对信息。通过比较基于对胴体进行目视检查（无切口、无触诊）的肉类检验方法与常规肉类检验方法所得结果可以得出结论，两种方法对许多异常情况的检测效果相同。还给出了一些进一步研究的建议。
