The possible colonization of the intestines and contamination of broilers after transport to the slaughterhouse with Campylobacter strains present in cleaned and disinfected transport containers was investigated. Seven broiler flocks with a Campylobacter-free status were sampled once just before loading at the farm and once just before slaughter. On both occasions, samples were also taken from the exterior of the birds and from the intestinal content. Transport containers used to transport the flock were sampled on the farm just before loading the birds. Campylobacters were enumerated and genotyped by flagellin gene A PCR-restriction fragment length polymorphism and pulsed-field gel electrophoresis. In total, 25 of the 35 sampled containers were Campylobacter contaminated, and 30 genotypes were found. Three broiler flocks became colonized on the farm between initial status determination and transport to the slaughterhouse, and three Campylobacter-free flocks were externally contaminated after transport. In none of the seven flocks was evidence found of intestinal colonization or cocolonization due to transport in Campylobacter-contaminated containers.
