These small tapeworm cysts (tÆnia saginata) are about the size of a pea and found in the flesh of cattle, which become infected by eating food or drinking water which has been contaminated by the feces of persons harboring adult tapeworms. Then again, the person becomes infected by eating raw or rare flesh of cattle infected with the larva stage of Measly Beef. Great care should be exercised to prevent cattle from becoming infested with this parasite. Persons’ feces should not be placed where it will infect food or drinking water that is consumed by cattle.
