Looks like trichinellosis from the encysted larvae. The site (tongue), too, is pretty classic.
Trichinella spiralis is the most common species worldwide. I know in Canada we tend to worry more T. nativa because of the Arctic; not sure about the continental USA (though I guess Alaska would have T. nativa as well!).
Trichinella spiralis
In the world: pork
In the US: poorly cooked bear meat.
(this is a guess)
BW in Vt
Trichinella spiralis or species.
T spiralis is found worldwide but there are several other species.
I am not experienced with internal structures seen the cross section except the round structures appear to be stichosomes. Usually I have seen only encapsulated larvae in other e-cases. Consumption of raw and undercooked infected meat esp pork is a risk factor
