Campylobacter jejuni and C. coli have been associated with gastrointestinal disorders in human beings, due mainly to the consumption of chicken meat. Despite control measures for reducing contamination by these bacteria, the detection of Campylobacter in carcasses after chilling remains high. A total of 105 carcasses were assessed by the horizontal detection method in five federally inspected slaughterhouses in southern Brazil in 2012 and in the first three months of 2013. Campylobacterwas isolated in 37.1% of the carcasses, of which 97.5% contained C. jejuni and 2.5% were infected by C. coli. The rate of positive carcasses across the slaughterhouses ranged from 0 to 71.4%. Determining the occurrence of Campylobacter among flocks is crucial for estimating the microbial load at specific points along the slaughtering process and for minimizing the risk of contamination of end products by Campylobacter.
