The anatomical-pathological findings, recorded as routine meat inspections at the abattoir, are a valuable information source, enabling conclusions in relation to the herd's health status. However, farmers often question the exactness and repeatability of such findings. To examine the repeatability of the meat inspection, the findings of 20 selected carcasses and 20 organs with 11 veterinarians and meat inspectors have been analysed in order to proof the repeatability of anatomicalpathological findings. The accordance of the results has been calculated by making use of Kendalls Konkordanzkoeffizient W and feature-related percentage for agreement. The results for kidneys (82 % agreement) and pericarditis (82 %) were corresponding to a high degree among the meat inspectors. In contrast, the assessments of lesions of lungs (25 %), liver (30 %), skin (31 %) and pleuritis, (38 %) differed notably. In order to improve the validity of the data and their acceptance as a tool for quality assurance it is recommended to continuously analyse the differences between meat inspectors with regard to their individual diagnostic patterns. The implementation of a feed back mechanism is expected to reduce variation between meat inspectors and to improve the training effects in the use of the findings categories. © M. & H.

Objective: In this study, we highlight the aspects of animal welfare and food safety that have to be considered, if fattening pigs have been exposed to mixed feed containing an extensive overdose of selenium. Material and methods: After assessing a thorough anamnesis, clinical symptoms - mainly neurological disorders and spontaneous deaths - were recorded among affected pigs. In order to rule out notifiable diseases and to confirm the presumptive diagnosis "selenium toxicosis", the examination was extended to further samples. Ani - mals were then selected for pathomorphological and histological examination, and blood, tissue and feed samples were submitted to laboratory testing to determine the selenium concentration. Results: Overall, 751 growing and finishing pigs were exposed to the feed containing an accidental overdose of selenium. Assuming the selenium was brought into the mixed feed only by the mineral supplement, it was calculated that this was loaded with 2.5 g/kg dry matter. Nearly all pigs either showed clinical symptoms or died spontaneously within 72 hours following exposure. Taking this and further aspects of animal welfare and food safety into account, decision was made to cull all pigs that were still alive. Conclusion: This case report highlights the welfare issues and aspects of food safety that should be considered by the attending veterinarian, when severe outbreaks of diseases like toxicosis are not managed by authorities. © Schattauer 2010.

The German Salmonella Monitoring Programme started by the QS-System in 2002 (Blaha, 2004) is mandatory due to the so-called "Salmonella Regulation for Pigs" since 2007 (Anonym, 2007). The Regulation does not clearly prescribe the specific muscle which is to be taken as source of the meat juice. Thus, at different slaughter plants meat samples are also taken from different muscles and several scientific papers describe various muscles as source of the meat juice, too. The objective of this study was to compare the serological results of meat juices from three different locations (diaphragm pillar, neck, belly muscle) to each other and to those of the blood serum from exactly the same animals. All samples were simultaneously tested for Salmonella antibodies by two serological tests (Salmotype ® Pig Screen, LDL, Germany; HerdChek® Swine Salmonella, IDEXX, Germany). Comparisons were carried out between the various sample kinds per animal and between the two test systems. The analysis of all results of the meat juices revealed in both test systems a clear decline of the OD% values from the diaphragm pillar to the neck to the belly muscle. The average OD% values of all samples were higher when measured by the HerdChek® ELISA (IDEXX, Germany) than by the Salmotype® ELISA (LDL, Germany), especially in blood serum. Since the results of the meat juice samples gained from the diaphragm pillar were in both test systems by far the closest to the results of the corresponding serum blood samples, it is recommended to amend the "Salmonella Regulation for Pigs" by prescribing meat from the diaphragm pillar as the only muscle for gaining meat juice. © 2011 Schlütersche Verlagsgesellschaft mbH & Co.
