If vacuum sealed properly, I believe you can freeze food indefinitely. I was rummaging around in the freezer a couple months ago and found a rib eye that I put in there in 2002. Grilled that sucker up and it was as good as if I had just brought it home from the market. I know, don't say it. I should check the freezer more often, but I kinda adhere to the LIFO freezer management philosophy. I'm almost afraid to go all the way to the bottom. No telling what may be lurking there.
