Successful trichinae control programs by the U.S. pork industry have nearly eliminated the disease in domestic swine raised in confinement, but hogs raised outdoors in close contact with rodents and other wildlife have an increased chance of acquiring Trichinella infection.

Trichinellosis, also called trichinosis, is a disease that people can get by eating raw or undercooked meat from animals infected with the microscopic parasite Trichinella.
