This document outlines a research project that aims to identify key reservoirs and environmental drivers of Campylobacter infections, analyze seasonal variations in pathogen levels and their impacts on exposure and disease, and understand transmission pathways to inform control strategies. It describes 5 studies that will analyze historical data patterns of risk, Campylobacter ecology on farms, landscape exposure sources, economic costs and intervention assessments, and alternative future risk projections. The project is a collaboration between multiple UK universities and institutions led by the University of Liverpool.
