Question: are your freezers self or manual defrosting? Food stored in a self defrosting freezer has a much shorter shelf life.
I hope your food is dated. Start with the date. Seafood/fish - six months in a manual defrost freezer. Either use quickly or toss. Veggies about the same. Bread products - 3 months or less. Nothing over a year.
Ummmm.... say what?
If the food is frozen, it is frozen. Now, if you are referring to freezer burn, just vacuum seal your food before you freeze it. If the vacuum bag leaks (not often, but it happens) it's no worse than a zip-lock bag.
With a good, tight vacuum seal, I easily get up to a year out of proteins, if I don't use them before that.
