“…The overall detected prevalence of infection in the cattle was generally lower than observed in other studies in Tanzania e.g. up to 0.7% reported in indigenous zebu in Arusha [32] . Also the overall prevalence of doubtful or inconclusive reactors (10%) was high and not comparable to the findings reported from eastern zone of Tanzania (from 6.0% to 7.5%) [33,34] .…”

“…Melanosis is characterised by an abnormal accumulation of melanin pigments in various body locations (Perestrelo-Vieira et al 2000;Mellau et al 2010) and leads to carcass condemnation (Regulation (EC) 854/2004). In pigs, melanin pigment is usually present in black breeds or crossbreeds, and is located in the abdominal fat and/ or mammary parenchyma of sows and even in the abdominal fat of boards.…”

Ante mortem and post mortem carcass condemnation records could be of use as a potential database for the study of swine diseases, epidemiology or animal welfare. Thus, the aim of this study was to investigate the causes of ante mortem rejections and post mortem carcass condemnation of pigs intended for human consumption during a 78-month period. The records considered for study were, date of slaughter, total pigs slaughtered and total number of ante mortem rejections (deaths during transportation and deaths in the pens) and post mortem carcass condemnations (osteomyelitis, caseous lymphadenitis, erysipelas, cachexia, pale, soft and exudative meat (PSE), bloody meat, muscular necrosis, purulent nephritis, purulent metritis, jaundice, meats from febrile pigs and peritonitis). The influence of several factors such as year, season, mandatory fulfilment of a food chain information form (FCIf ) and compulsory certification of swine drivers/transporters on ante mortem rejections and post mortem carcass condemnation was also studied. A total of 161 001 pigs slaughtered resulted in 238 (0.15%) ante mortem deaths, 160 763 pigs processed for meat consumption (99.7%) and 392 (0.24%) carcass condemnations. The ante mortem rejections revealed that 146 pigs (61.3%) died during transportation whereas 92 (38.7%) were rejected due to death in pens. The main causes of carcass condemnations were osteomyelitis (38.5%), granulomatous lymphadenitis (22.7%) and pleurisy/pneumonia (21.2%). A relationship was found between the month and ante mortem condemnations (P < 0.01), death losses during transport (P < 0.01) and between compulsory certification of animal transporters and deaths by transportation (P < 0.05). During the cold season, the probability of ante mortem rejections (OR = 1.84; CI 95%: 1.32-2.59) and death in pens (OR = 1.62; CI 95%: 1.02-2.57) was higher. The compulsory fulfilment of a food chain information form was not revealed to be significantly linked with the total number of carcass condemnations although the odds of ante mortem rejections were higher (OR = 2.10; CI 95%: 1.44-3.08) when it was not mandatory. Higher post mortem condemnations compared to ante mortem condemnations can be explained by the fact that several post mortem findings are asymptomatic in live animals. A progressive decrease in losses during transport was associated with on-farm improvements in animal welfare measures in addition with compulsory training of animal transporters. However, the consistent values of deaths in pens throughout the study period, with an increase during the winter, indicate a need for an improvement in the thermal conditions of the holding area in slaughterhouse. Regarding the post mortem condemnations, the improvement in animal welfare conditions may explain the decrease in osteomyelitis condemnations while the environmental origin of granulomatous lymphadenitis may be associated with region, climate or with the presence of hosts that may explain the influence of the time of year on its variations. The FCIf was i...

“…No trabalho de (Fruet et al, 2013) observou-se 5.511 órgãos condenados, com destaque para as lesões por aspirações de sangue (n=1.231 animais) podendo estar associados a doenças, contudo a maior frequência pode ter sido causada por ineficiência de tecnologia de abate durante o procedimento de abate (Mellau et al, 2010). A classificação dos pulmões pode ser realizada quanto à presença ou ausência de hepatização pulmonar com características de pneumonia enzoótica, as que em geral, não causam desvios das carcaças da linha de inspeção (Alberton & Mores, 2008).…”

RESUMO.O presente trabalho tem por objetivo apresentar dados coletados em 11 propriedades que abastecem um frigorífico de Santa Catarina. Foram analisados 2.691 suínos abatidos no ano de 2016 sobre as principais causas de condenações de vísceras vermelhas ou comestíveis em abates. Foram identificadas as seguintes causas por condenações de carcaças: pneumonia enzoótica 52,08%, aspiração por sangue 20,28%, aspiração por líquido 17,01%, aderência de pleura 3,04%, atelectasia pulmonar 0,89%, enfisema pulmonar 0,18%, abscesso pulmonar 0,26%, pleuropneumonia 2,52%, lesão por Ascaris suum 16,05%, perihepatite 1,89%, cirrose hepática 3,04% e pericardite 6,91%. As principais condenações foram por pneumonia enzoótica, aspiração por sangue, lesão por Ascaris suum e pericardite. Durante a inspeção as lesões podem ser provenientes de diferentes fatores, entre eles, falhas no processo tecnológico de abate, ausência de um programa de vacinação e erros de biossegurança nas propriedades, associado com o manejo precário. Diante disso, a redução da prevalência das lesões que culminam em condenação das carcaças pode ser minimizada com o treinamento de funcionários para minimizar as perdas econômicas na indústria e para os produtores de suínos juntamente com um rigoroso controle sanitário nas granjas. Palavras-chave: carcaças, inspeção sanitária, lesões post mortem, suínos terminados Economic damages by condemnation of viscera in red of pigs slaughtered Santa CatarinaABSTRACT. The present work has as objective, with data collected in 11 properties that provide a refrigerator of Santa Catarina. A total of 2.691 pigs slaughtered in 2016 were analyzed as the main causes of condemnation of red or edible viscera in slaughter. Encephalic pneumonia 52.08%, blood aspiration 20.28%, fluid aspiration 17.01%, pleural adhesion 3.04%, pulmonary atelectasis 0.89%, pulmonary emphysema 0.18%, pulmonary abscess 0.26%, pleuropneumonia 2.52%, Ascaris suum lesion 16.05%, perihepatitis 1.89%, cirrhosis 3.04% and pericarditis 6.91%. As main condemnations for enzootic pneumonia, blood aspiration, Ascaris suum injury and pericarditis. During the inspection as lesions can be disclosed of different factors, associated with precarious management, absent from a vaccination program and biosafety errors in properties, associated with poor management. In view of this, a reduction in the prevalence of injuries that culminate in condemnation of carcasses can be minimized by training employees to minimize economic losses in industry and to pig producers with strict sanitary control on farms.
