Can pork cause tapeworms?
With pork tapeworm we have TWO stages of the parasite that can cause problems with the human. We can eat improperly cooked or cured pork, ingest the still-viable cysts, and develop the tapeworm in our intestine (taeniasis). But we may also be infested with the cystic stage through eating raw vegetable matter that has been contaminated with human sewage. This is called cysticercosis, and although the cyst is small (about the diameter of a pencil), it can form in the brain, spinal cord, eye, liver, and cause damage there. Prevention here is thoroughly washing (or cooking) plant food, and keeping hands washed to avoid auto-infection.

Complications
- Tapeworm infection is caused by ingesting food or water contaminated with tapeworm eggs or larvae. If you ingest certain tapeworm eggs, they can migrate outside your intestines and form larval cysts in body tissues and organs (invasive infection). If you ingest tapeworm larvae, however, they develop into adult tapeworms in your intestines (intestinal infection). An adult tape…
Prevention
- Many people with intestinal tapeworm infection don't have symptoms. If you do have problems from the infection, your symptoms will depend on the type of tapeworm you have and its location. Invasive tapeworm infection symptoms vary depending on where the larvae have migrated.
