DISTRIBUTION AND NUMBERS OF CAMPYLOBACTER-IN NEWLY SLAUGHTERED BROILER-CHICKENS AND HENS

If Campylobacter is present in the intestinal tract, broiler carcasses become extensively contaminated during the slaughter process. To determine the distribution and numbers of Campylobacter jejuni/coli in newly slaughtered broiler chickens and hens, a total of 100 birds from six Campylobacter-positive flocks were sampled at three Swedish processing plants. Campylobacters were isolated in 89% of neck skins, 93% of peritoneal cavity swab samples and in 75% of subcutaneous samples. Muscle samples were only very sparsely contaminated. It is likely that the feather follicles are the orifices where C. jejuni/coli is introduced into the subcutis layer.
