Which animal is specifically mentioned as a common reservoir for Yersinia enterocolitica?

• A. Cows
• B. Pigs
• C. Chickens
• D. Fish

Answer: (B)

Pigs are the animal most commonly associated with Yersinia enterocolitica. Swine can carry the bacterium in their intestines and tonsils, and pork products often become contaminated during slaughter or processing. When people eat undercooked pork or foods cross-contaminated with pork juices, they can acquire yersiniosis. Other animals like cows, chickens, or fish aren’t the primary reservoirs linked to this organism, so the pig is the best choice to explain how humans typically become infected.
