The population and range of feral pigs in the United States are rapidly expanding, yet key knowledge gaps exist regarding their role in the ecology and transmission of foodborne pathogens. Our objectives were to estimate the prevalence of Campylobacter jejuni and Campylobacter coli shedding among feral pigs throughout Texas and to identify risk factors for positive status. Faecal samples were collected from feral pigs in Texas from February 2014 through May 2015, and target organisms were detected using PCR assays. The prevalence of C. jejuni shedding was 1.6% (6/370), and the prevalence of C. coli shedding was 3.5% (13/370). C. coli shedding was significantly more common (p = .008) among female pigs than among male pigs. Feral pigs may represent a source of human campylobacteriosis.
