“…Of the 15 causes of carcass condemnation (Table 1) osteomyelitis (38.5%), granulomatous lymphadenitis (22.7%), pleurisy/pneumonia (21.2%), abscesses (8.4%), peritonitis (2.6%) and generalised melanosis (1.8%) were most prevalent whereas the other causes account for under 1% of condemnations. Moreover, the causes of carcass condemnations were consistent with those observed by Martinez et al (2007). Flesja and Ulvesaeter (1979) reported mange as the main cause of carcass condemnation although abscesses and peritonitis represented approximately 50% of condemnations, in comparison with our findings.…”

“…The literature regarding pig carcass condemnation at slaughterhouses is scarce (Martinez et al 2007) and research on carcass condemnation has focused on other species (Ansari-Lari and Rezagholi 2007; Alton et al 2010;Regassa et al 2013). However, recent studies have reported the utilisation of carcass condemnation data as a predictive tool for swine diseases (Thomas-Bachli et al 2012, 2014.…”

“…The literature available regarding the causes of carcass condemnations in pigs is scarce. However, reports on the partial condemnation of swine carcasses and its economical implications, condemnation causes in growthretarded pigs and the utilisation of records of pig condemnations as a spatial disease surveillance method have recently been published (Tuovinen et al 1994;Tiong and Bin 1999;Martinez et al 2007;Thomas-Bachli et al 2012, 2014.…”

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...

“…Despite its low mortality rate, M. hyopneumoniae infections are associated with high morbidity rates. The agents adherence to the cilia of the epithelial cells in the lower airways affects the mucociliary defense mechanism and assists in the entrance of other bacteria, resulting in delayed growth in the affected animals and carcass condemnation at slaughter (Desrosiers 2001, Srinivasan et al 2002, Martínez et al 2007, Hansen et al 2010.…”

Nested-PCR for the detection of Mycoplasma hyopneumoniae in bronchial alveolar swabs, frozen tissues and formalin-fixed paraffin-embedded swine lung samples: comparative evaluation with immunohistochemical findings and histological features

et al. 2012

Pesq. Vet. Bras. 32(8) The diagnosis of Mycoplasma hyopneumoniae infection is often performed through histopathology, immunohistochemistry (IHC) and polymerase chain reaction (PCR) or a combination of these techniques. PCR can be performed on samples using several conservation methods, including swabs, frozen tissue or formalin-ϐixed and parafϐin-embedded (FFPE) tissue. However, the formalin ϐixation process often inhibits DNA ampliϐication. To evaluate whether M. hyopneumoniae DNA could be recovered from FFPE tissues, 15 lungs with cranioventral consolidation lesions were collected in a slaughterhouse from swine bred in herds with respiratory disease. Bronchial swabs and fresh lung tissue were collected, and a fragment of the corresponding lung section was placed in neutral buffered formalin for 48 hours. A PCR assay was performed to compare FFPE tissue samples with samples that were only refrigerated (bronchial swabs) or frozen (tissue pieces). M. hyopneumoniae was detected by PCR in all 15 samples of the swab and frozen tissue, while it was detected in only 11 of the 15 FFPE samples. Histological features of M. hyopneumoniae infection were presented in 11 cases and 7 of these samples stained positive in IHC. Concordance between the histological features and detection results was observed in 13 of the FFPE tissue samples. PCR was the most sensitive technique. Comparison of different sample conservation methods indicated that it is possible to detect M. hyopneumoniae from FFPE tissue. It is important to conduct further research using archived material because the efϐiciency of PCR could be compromised under these conditions.
