Abstract / Zusammenfassung

For process control, Reg. (EC) No 2073/2005 lays down process hygiene criteria for Salmonella spp. and Campylobacter spp. on carcasses of broilers. The purpose of this study was to compare the microbiological condition of neck skin and breast skin ­samples of broilers after chilling. In total, 115 carcasses were sampled and from each carcass neck skin and breast skin samples were examined for aerobic plate count, Enterobacteriaceae count, Salmonella spp. (qualitative), and Campylobacter spp. (semi-quantitative and qualitatively by PCR). Salmonella could not be detected. Wilcoxon-test for paired samples showed significant differences between the sampling locations of each carcass for aerobic plate count (APC), Enterobacteriaceae count and Campylobacter spp., respectively. As assumed, APC values for neck skin samples of all microbial parameters were higher than the ones for breast skin samples. Campylobacter-positive PCR results were obtained from 77 carcasses. 72 carcasses out of these were positive in both sampling sites, which indicated a 93.5 % agreement of positive samples, and a kappa of 0.64. Therefore, breast skin could be used for detection of Campylobacter spp., although detection rates were significantly lower for breast skin (p < 0.001). The opportunity to use breast skin if not enough neck skin is available is given in Reg. (EC) No 2073/2005, but if breast skin is used widely, it must be considered that the detection rates would be lower due to the sampling location. To prevent future uncertainty and possible ­underestimation of Campylobacter rates in poultry the sampling site used should be an indispensable part to assess the microbial result.
