There's probably more than one parasite being discussed here. Maybe liver flukes? What I have found is tapeworm cysts, they do look similar to photo by H2ofowlr but with only one "glob". In the mulie, they were only between the muscles layers. In the moose, they were in bubbles in the meat, too. Didn't check the livers, but have heard of liver parasites on the west side in the past.
