Trichinellosis surveillance - United States, 2002-2007.

Problem/condition: Trichinellosis is a parasitic disease caused by roundworms of the Trichinella genus. Humans are incidental hosts who become infected after ingestion of raw or undercooked meat containing encysted larvae of Trichinella spp. Common signs and symptoms of trichinellosis include eosinophilia, abdominal pain, fever, periorbital edema, and myalgia.
