If you wouldn't eat anything with worms....you wouldn't eat meat or vegetables. All animals have worms..even cattle. These worms are picked up at the hoofs and they travel up the mussels to the back straps. Cattle have them all the time. Fish have worms..I don't know of any animal that does not have worms of some sorts. They are ok ...just fully cook as you do for any meat. You can see them in calves as small under skin cyst like. Enjoy the meat....lol If I were you...don't look for small things ....you may not eat ever again. LOL All deer have these worms...you can see where they have left the back strap and crawled out ...there will be small holes in the back straps. The cattle men on this web can tell you what they are called...I forgot ...old age. " mussel worms" one web said. Go into the grocery meat market...look close at the steaks...you will see small pin hoes with a little blood. This is the same thing....lol Deer also have worms that will crawl out of their nose if ya hang them up by the back legs. Cut a slice in their gut or intestines you will probably see tape worms. Very long flat worms...some three feet long. Cook some of the deer tonight and don't think what might be in the meat...hee heee.

When ceviche is properly prepared, the fish is frozen to kill any parasites.

I have never seen them in a deer, but I do not think it would bother me. I would just package up the meat and give it to a friend.
