Trichinella spiralis is a nematode parasite, occurring in rodents, pigs, horses, bears, and humans, and is responsible for the disease trichinosis. It is sometimes referred to as the pork worm due to it being found commonly in undercooked pork products.
Trichinellosis can be contracted by eating raw or undercooked pork infected with the parasite Trichinella spiralis. Disease symptoms include abdominal pain, diarrhea, nausea, vomiting and weakness. Digestive system symptoms typically begin within 24 to 48 hours after eating contaminated, undercooked pork. Muscle and joint pain, cough, headache, fever and chill may develop weeks after the initial symptoms. Early treatment of Trichinellosis is important for permanently eliminating the parasite from the body.
