Proposal of a Standard for the Condemnation for Turkey Carcasses Due to Fowlpox

This study aimed at proposing a new technical criteria for condemnation of turkey carcasses due to fowlpox in turkeys as a contribution for the work of the Brazilian Federal Meat Inspection Service. Skin samples from 30 carcasses of a flock of 840 turkeys (Meleagris gallopavo), previously vaccinated for fowlpox and slaughtered in June 2013, were collected. Samples were submitted to histological examination under light microscopy. The virus was identified using standard PCR techniques. The main histological findings were hyperplasia and hydropic degeneration of the epithelium and the presence of intracytoplasmic eosinophilic inclusion bodies. PCR results yielded 83.3% positive and 16.7% negative samples. Fowlpox virus is species specific, and there are no reports of its occurrence in mammals. The macroscopic and microscopic findings of the skin lesions do not justify the total condemnation of carcasses of poultry affected with fowlpox, except in cases of cachexia or repulsive appearance, as established by SIF regulation.

Estudo anatomopatológico em tecidos condenados pelo Serviço De Inspeção Federal (SIF) por suspeita de tuberculose / Anatomopathological study in condemned tissues under suspicious of tuberculosis by the Brazilian food Safety and Inspection Service

A metodologia utilizada pela inspeção animal na linha de abate tem gerado controvérsias entre o que deve ser condenado e liberado ao consumo. Acredita-se que órgãos e carcaças estejam sendo condenados por tuberculose sem apresentarem lesão microscópica compatível com tal patologia. O objetivo deste trabalho foi identificar as lesões microscópicas encontradas em amostras de linfonodos condenados por tuberculose pelo SIF (Serviço de Inspeção Federal). Foram coletadas 61 amostras condenadas pelo SIF por suspeita de tuberculose. Os linfonodos foram fixados em formalina tamponada 10%, recortados, processados rotineiramente e incluídos em parafina. Na avaliação realizada pela coloração de Hematoxilina e Eosina (H&E), observaram-se 55 granulomas tuberculóides e três granulomas actinomicóides, um linfonodo apresentando cristais com leve reação inflamatória e dois hiperplasia linfóide. Concluímos, portanto, que o índice de acerto de condenação de lesões de linfonodos por tuberculose foi satisfatório, entretanto poderia ser melhorado.

The methodology used during the Animal Standard Meat Inspection (SIS) has been controversial in the decision to condemn or approve materials for human consumption. The aim of this study was to identify the microscopic lesions found in lymph node tissues condemned for tuberculosis by the Brazilian SIS. Sixty-one condemned lymph nodes were collected, fixed in buffered formalin 10% and submitted to histological processing. By evaluating the condemned tissues with H&E stain, 55 tuberculoid granuloma were found, as well as three actinomycosis granuloma, 2 presenting lymphoid hyperplasia and 1 crystal deposition. The misdiagnosis rate in the samples condemned due to tuberculosis was satisfactory, however it can be improved.

Principais causas de condenação no abate de perus (Meleagris galopavo) em estabelecimento sob inspeção federal em Santa Catarina / Main causes of condemnation at turkeys slaughter of (Meleagris galopavo) in property under federal inspection in Santa Catarina

The aim of this study is to better comprehend the main causes of condemnation in a turkey slaughterhouse, located in southern Brazil, to correlate total and partial condemnation losses in 5-years period. Nosagraphic maps prepared by the Federal Inspection Service, in which all the rejection causes are stated, were used. The main causes of total condemnation were contamination, excessive scalding, repugnant aspect, dermatitis, colibacillosis and the main causes of partial condemnation were airsacculitis, contamination and contusion/ fracture. In the slaughterhouse plant studied, there was a decrease in the total condemnation and increase in the partial condemnation in the last 2 years. It was also noticed that the overall condemnation rates decrease during winter. (AU)

O presente trabalho teve como objetivo estudar as principais causas de condenações em um abatedouro de perus, localizado na região sul do Brasil, para correlacionar as perdas por condenações total e parcial de carcaças, por um período de cinco anos, comparados com outros estudos já efetuados. Para tal, utilizaram- se os mapas nos gráficos, elaborados pelo Serviço de Inspeção Federal nos quais constam todas as casuísticas de rejeição. As principais causas encontradas de condenações totais foram contaminação, escaldagem excessiva, aspecto repugnante, dermatose e colibacilose, e as principais causas de condenações parciais foram aerossaculite, contaminação e contusão/fratura. Verificou-se ainda que, na planta estudada, houve queda nas condenações totais e aumento das condenações parciais nos últimos dois anos e que os índices gerais de condenações reduzem nos períodos de inverno.
