Campylobacter are estimated to cause 2.4 million illnesses annually in the United States, and most of these illnesses are food-related. Pigs can be sub-clinically infected with these pathogens, and fecal contamination of meat during processing is a food safety risk. The goal of this study is to determine the clonal relatedness of selected Campylobacter coli isolates from an individually-identified cohort of pigs collected from five smaple types on the farm to processing continuum
