Which animal is listed as a common source of Trichinella in humans?

• A. Beaver
• B. Bear
• C. Walrus
• D. Boar

Answer: (B)

Trichinella infection occurs when people eat meat that contains encysted larvae in the muscle. The larvae survive in the meat and can cause illness when consumed. Among the animals listed, bear meat is a well-recognized common source in many regions, especially where wild game is eaten, because bears can harbor Trichinella and outbreaks have been linked to undercooked bear meat. While beaver, walrus, and boar can also carry the parasite, bear meat is repeatedly highlighted in public health and exam contexts as a typical source. The best prevention is cooking meat thoroughly to inactivate the larvae and avoiding consumption of undercooked wild game.
