I haven't checked this out recently, but I used to buy f.d. food for lots of group backpack trips, maybe 30 years ago when Mountain House was king. As you may know members of the Mormon church believe that they should have six months worth of food stockpiled in their basement for the next Armageddon. As a result, they buy f.d. food, air dehydrated food, bags of wheat, water filters, and all of that stuff. I found a local store that supplied the local Mormon community, and they had all sorts of special deals on a case of M.H. assorted f.d. meat, for example. That was six #10 size cans. Another one was six #2-1/2 size cans. As long as they were sealed cans, they kept. Once I opened a can to transfer it to bags, it would be perfect for about a week or so. Then its flavors and texture would slowly decline.
