Investigations of a free‐range broiler flock during the rearing period and at the slaughterhouse by polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP) of the flagellin ( fla A) gene ( fla A typing) have shown that poultry carcasses are contaminated by Campylobacter spp. strains which were previously present in the poultry faeces. Moreover, the investigation of the previous and the following batches in the processing plant using fla A typing have shown that cross‐contamination between batches coming from different flocks occurs and is also a risk factor for the presence of Campylobacter spp. on poultry carcasses.
