These results prove that slaughtering Campylobacter-negative flocks does not introduce Campylobacter
into the abattoirs and indicate that although carcasses and chicken products originating from the
Campylobacter-negative flock were cross-contaminated with Campylobacter from the Campylobacter positive flock slaughtered immediately before, the Campylobacter contamination levels were lower than
those in carcasses and chicken products from Campylobacter-positive flocks.
