Human enteritis caused by Campylobacter spp. is, doubtless a worldwide problem. Particularly endangered is human population in countries with intensive animal husbandry. Campylobacter spp. can be transmitted from animals to humans in several ways, mostly by contaminated meat, milk and water. There is assumption that people can be infected by inadequate cooked chicken meat. Campylobacter jejuni is important cause of human gastroenteritis. Infectious dose, according to some authors, can be less than 500 cfu/mL or g of foodstuff. According to these data, the occurrence of Campylobacter jejuni in meat and liver of slaughtered chicken has been examined in this research. As a testing material, 115 meat samples (2-3 g of inner part of m. pectoralis) and 115 liver samples (2-3 g) from the same carcasses were used. Samples were collected from the chicken from the slaughterhouse. For isolation of Campylobacter jejuni both liquid medium Brucella broth with antibiotics and solid medium by Skirrow were used. Microaerophylic conditions were achieved using McIntosh tank with Genbox microaer bags. For Campylobacter jejuni identification catalase test, hypurate dissolution and growth temperature were used. Campylobacter jejuni was detected in meat of 35 chicken carcasses (40.25%) and in 46 liver samples (52.9%). Occurrence of Campylobacter jejuni in chicken meat and liver is less compared to data of some authors reporting the occurrence of this bacterium in 82.60% chicken meat and in 85% of liver samples. These results are similar to the results obtained in our earlier investigations.
