People have eaten chunks of frozen Mammoths and lived to tell the tale. It can start to taste funny if you leave it in the freezer to long, freezer burn. Pork is especially prone to an off taste if left in the freezer long.

it's is safe to eat , its just might taste a little off

If it tastes funny why in the world would you eat it? You from a third world country?

Bout one year

You should look into canning some of your venison in the future.

When butchering we double wrap 1 lb venison portions in plastic wrap and then in freezer paper and tape it shut. Some hasn't been eaten until 4 or 5 years later and is just as good as the stuff eaten after a month. No freeezer burn when sealed properly. Trying to protect a large piece like a hindquarter seems almost impossible.
