Trichinosis Transmission

Facts about the transmission of trichinosis:

  • Trichinosis occurs after eating meat that contains cysts.
  • Cysts hatch within the human intestinal tract after exposure to stomach acid.
  • Cysts produce adult roundworms that produce larvae.
  • Larvae migrate through the intestinal wall and into the bloodstream.
  • Larvae form cysts in the muscle and other tissues.
  • Adult worms eventually die and pass in the stool.
