Scientists have analysed genetic regions in chickens that are linked to the resistance of campylobacter, the leading cause of food poisoning in people. Their study revealed that while there are genetic factors that influence the colonisation of campylobacter, they only play a minor role, meaning that a better understanding of non-genetic factors is required to further reduce campylobacter levels in poultry. The research was led by the RVC and the Roslin Institute in collaboration with the poultry breeding company Aviagen and published in the journal Nature
