Transmission cycle of Taeniasis

1) person w/adult tapeworm living in person gut sheds eggs in the stool
2) a pig then eats the eggs in the stool
3) eggs develop into larvae and form cysts (cysticercosis)
4) Humans who ingest undercooked or raw infected pork swallow the cysts in the meat
5) larvae come out of the cysts in the gut and develop into the tape worm
