Trichinella are threadworms that can infect wildlife (including bears, foxes, and seals) and domestic animals (especially pigs, dogs, and horses). These worms are about 1mm long and can be found throughout the world. When humans consume raw or undercooked meat from an infected animal, people can be infected with Trichinosis. This disease is currently rare in humans, but testing is still necessary because trichinella are commonly found in many wildlife species.
