The larva then makes its way to the herbivore's muscle tissue, where it metamorphoses into an oval worm about 10 millimetres (0.39 in) long, with a scolex that is kept internally. When the definitive host eats infested raw or undercooked meat from an intermediate host, the worm's scolex pops out and attaches itself to the gut, when the adult ...

It is entirely covered by a tegument. The body is white in colour and consists of three portions: scolex, neck, and strobila. The scolex has four ...
Routes of exposure and infection include ingestion of undercooked meat, drinking infected water, fecal–oral transmission and skin absorption. Some types of helminths and protozoa are classified as intestinal parasites that cause infection—those that reside in the intestines. These infections can damage or sicken the host (humans or other ...
The meat had been frozen in a household freezer for 45 days. Hunting black bears is legal in Canada and many U.S. states. The family made kebabs with the thawed meat, alongside grilled vegetables.
