Decisions as to the disposition of swine carcasses with lesions attributable to a mycobacterial infection are based upon a lesion criterion which is used as a diagnostic test by federal meat inspectors. Using this criterion, a federal meat inspector classified 58 of 100 pigs as "passed for cooking" and the other 42 pigs passed. Of the 58 pigs passed for cooking and the 42 pigs passed, mycobacterial isolations were made from the lymph nodes of 33 and 15 of the animals, respectively. The lesion criterion as a diagnostic test has the following attributes: 70% sensitive; 53% specific; 23% index of performance; 57% positive accuracy; and 67% negative accuracy.
对于患有可归因于分枝杆菌感染病变的猪胴体处置决策，是基于一项病变标准做出的，该标准被联邦肉类检验员用作诊断测试。根据这一标准，一名联邦肉类检验员将100头猪中的58头归类为“通过烹饪”，另外42头猪也通过了。在这58头通过烹饪的猪和42头通过的猪中，分别从33头和15头动物的淋巴结中分离出了分枝杆菌。作为诊断测试的病变标准具有以下属性：70%敏感性；53%特异性；23%性能指数；57%阳性准确率；以及67%阴性准确率。
