I'd use it without hesitation--I vacuum seal all our venison and wild boar, and have never had a problem with it. As long as the seal has held, and there is no evidence of freezer burn, it should be just fine. In fact, after cleaning out my freezer last week, I found a perfectly sealed, vacuum-packed venison boned ham from 2003 (!) and pressure-cooked it with wine, garlic and other goodies. Tasted just fine, and none of us have died yet from it. I will note that I did throw out some things whose seal had failed, and showed extensive freezer burn. Sometimes those are just not worth saving. Leigh
