Resumo
The objective of the present study was to identify the main anatomopathological lesions in organs of condemned cattle during the post mortem inspection in a slaughterhouse in the south of the state of Espírito Santo, from March to June 2022. A total of 496 samples were collected from 1512 slaughtered animals, with the liver being the organ that presented the highest number of lesions. The main cause of condemnation was fasciolosis with 49.80% (n=247), followed by tuberculosis with 18.75% (n=93), telangiectasia in 16.33% (n=81), renal cyst in 8.06 % (n=40), liver abscess in 3.63% (n=18) and cysticercosis in 3.43% (n=17). Macroscopically, in cases of fascioliasis, white areas predominated, sometimes firm, sometimes creaking when cut in 63 (25.50%) livers; in cases of tuberculosis, multifocal granulomas predominated in lymph nodes (33/36; 91.66%), lungs (15/20; 75.00%), and liver (5/17; 29.41%); in cases of telangiectasia, the lesions were red to blackish areas in 60 (74.07%) of the livers; in the cases of renal cysts, the kidneys presented multifocal cysts in 40 (100%) and pallor in 32 (80.00%); in cases of liver abscesses, 100% (n=18) of the livers had this lesion; and in the cases of cysticercosis, viable cysts were observed in the masseter muscle (7; 41.17%) and tongue (1; 5.88%) and calcified cysts in the heart, kidney, liver and lymph node, all with 5.88%. The cases of fascioliasis, telangiectasia, renal cyst, liver abscess and cysticercosis, observed on macroscopy, were confirmed on microscopy; cases of tuberculosis observed in lymph nodes, lungs and liver on macroscopy were also confirmed on microscopy, however, cases on kidneys and spleen were not confirmed on microscopy. It was concluded that the main cause of organ condemnation was fasciolosis, followed by tuberculosis, telangiectasia, renal cyst, liver abscess and cysticercosis; the most condemned organ was the liver, with a predominant macroscopic lesion of white areas, sometimes firm, sometimes creaky when cut, and the most frequent microscopic alteration was degeneration of hepatocytes.
