The aim of the present study was to observe the occurrence of Campylobacter in chicken farms and in a slaughterhouse. A total of 120 samples were collected in three chicken farms: cloacal swabs (n=30), poultry litter (n=30), feed (n=30) and water (n=30) samples. In the slaughterhouse, 126 samples were collected: water samples (n=36), neck and chest skins (n=30), livers (n=30) and gizzards (n=30). Campylobacter was isolated in 40 (33.33%) chicken farm samples: 29 (96.6%) cloacal swabs, ten (33.3%) poultry litter and one (3.3%) water sample. Campylobacter jejuni was identified in 33 (82.5%) strains from chicken farms. In the slaugtherhouse, all the eleven (8.73%) isolated strains were identified as C. jejuni: ten (27.8%) water samples and one (3.3%) gizzard sample. The main contamination sources in chicken farms were the cloacal swabs, the poultry litter and, in small proportion, the water. In the slaughterhouse, the main critical points were the water from poultry evisceration and the gizzard collected from the small cooling tank.
