To be honest. I don't put a lot of faith in cans of food that has passed expiration. As for MREs I've only recently started eating the ones that the dates said were still good. The out of date ones dont show any real difference in flavor...let alone making me ill.
As for rice, beans and grains. It might be ok to put them in plastic bags, seal in an ammo can, then freeze in the deep freezer. You get the air tight seal, their stackable, and their frozen.
Damn....now if thats not the Okie coming out in me I dont know what is...
