Which of the following is NOT a common source of Campylobacter in people?

• A. Pork
• B. Poultry
• C. Dairy
• D. Beef

Answer: (A)

Campylobacter infections are most often linked to poultry, because birds commonly carry the bacteria in their intestines and contamination of carcasses during processing is frequent. Unpasteurized dairy is another well-established route since Campylobacter can survive in raw milk and dairy products made from it. Beef can also be a source, especially ground beef, due to contamination during slaughter and handling. Pork is not a common reservoir for Campylobacter, so it is less likely to cause illness from that organism compared with poultry, dairy, or beef. To reduce risk, cook poultry thoroughly, pasteurize dairy, and handle and cook beef properly to avoid cross-contamination.
