Final answer:
The food-borne parasite found in under-cooked pork is Trichinella spp, which causes trichinosis. While Toxoplasma gondii is another parasite associated with undercooked meat, Trichinella is specifically linked to pork.
Step-by-step explanation:
The food-borne parasite typically found in under-cooked pork is Trichinella spp. This parasite is responsible for causing trichinosis, a disease where larvae emerge from cysts in the undercooked meat and mature in the host's large intestine.
These larvae can then migrate to the muscles and form new cysts. While some parasites like Toxoplasma gondii can also be found in undercooked meat, Trichinella is specifically associated with pork.
Other parasites such as Taenia spp. and Diphyllobothrium latum are known as tapeworms and can be transmitted through various undercooked foods.
