Feedback:
Trichinosis is a disease caused by the ingestion of the encysted larvae of the roundworm from undercooked pork. These worms exist outside the intestinal tract and can seriously damage the tissues they invade. The worms do not spread rapidly through a large group of people unless they have all eaten the undercooked pork. They do not enter cells to alter human cellular function.
