This chapter highlights the important bacteriological and epidemiologic features related to thermotolerant Campylobacter species (C. jejuni and C. coli, and to a lesser extent C. lari) contamination in the human food chain. The genus Campylobacter belongs to the family Campylobacteraceae together with the genera Arcobacter and Sulfurospirillum. A recent study revealed that culturability and adhesion/invasion of C. jejuni are linearly related. The identification of several putative adhesion factors in C. jejuni was based mainly on experiments in culture cell lines. The application of discriminatory molecular subtyping methods (e.g., multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE)) was useful in clarifying some aspects of host association and source attribution. Evidence from epidemiologic studies and molecular subtyping investigations has identified poultry meat as a major vehicle for foodborne transmission of campylobacter enteritis. Future research and scientific collaborations among the medical, food, and veterinary professions are needed to substantially reduce Campylobacter contamination in the poultry meat chain. Research directions should focus on practical control options that would be appealing to stakeholders in the farm, slaughterhouse, and processing sectors. In addition, there are opportunities for the development of enhanced Campylobacter detection and quantification methods. Methods able to identify highly contaminated samples through online detection would be very useful, as this could help in identifying and excluding highly contaminated samples from the human food chain.
