I shot a deer last Friday. Just ate the backstrap tips tonight. Its been in the fridge since Friday. Never frozen.. Delish
I'd say after being frozen should be good at least a week. But, if it's been in your freezer for 2 years, then in the fridge for a week, could be questionable. Some of that depends on how well you packaged the meat.
I found too many of the vacuum sealed meat packages were getting punctured in the freezer and causing some freezer burn. I've been doing what I seen on meateater several years ago. Wrap in plastic wrap, remove as much air as possible, then wrap in butcher paper. I had deer meat in the freezer for 2 years in excellent condition.
Enjoy your kill friend
