Over the weekend I was helping an old man clean out two refrigerator/freezers. Way in the back of one of them I pulled out a large chunk of venison roast. He has the bag marked "1/18/18" and it is (or was) a fresh kill that he processed himself, threw in the freezer, and must have forgotten about this particular cut. He swears the meat is still good after two years since it has remained frozen since processed and said I could have it, but I'm a bit weary. It was packaged in THREE large ziplock freezer bags and nothing else. It actually looks okay, only a couple small spots where it looks to have freezer burn. Anyway, anyone here with more experience know if this meat is still safe to eat? I have never kept venison frozen for longer than about 6-12 months before, and I always vacuum seal mine. I'm sort of thinking that while it is still safe to eat after two years, the quality of the meat may not be very good. Thoughts? Thanks.
