If the meat has been wrapped well before freezing it will be fine. The main way frozen venison goes bad is due to freezer burn, just like beef or chicken. I use heavy duty freezer wrap and then use freezer paper and tape to seal the entire package. I have venison from 2003 still in my freezer and ate some last night for dinner and it had zero freezer burn on it. Once you open it you'll know. Its not going to spoil for a long long time in the freezer especially if you remove all the fat of the meat before you freeze, which is what I do. The fat is the first thing that goes bad, but it takes a very long time at freezer temperatures.
