- A tapeworm is a worm with a long, flat body that can live in human intestines. They can grow to 3 to 10 meters in length.
- Tapeworm infection usually occurs when a person eats or drink items that are contaminated with a tapeworm's eggs.
- Tapeworm infection is caused by one of four species: pork tapeworm, beef tapeworm, dwarf tapeworm and fish tapeworm.
- Most people who have tapeworms do not show symptoms. Those who do might feel weak, lose their appetite, lose weight or feel nauseated.
- People most at risk for tapeworm infection include those exposed to livestock, have poor hygiene or eat raw or undercooked meats.
