In before the Prepper ping?

My guess is that the quality is just fine.
I have 700 pounds of Wheat berries and beans, split peas, etc, in #10 cans from that same period that have been stored in terrible conditions, with wide ranging temperatures and temperature rarely, but at times having reached 110, I intend to keep my stuff until I die.
My plan is to buy newer, fresher stores in time, but that old batch will remain in storage as my “Stalingrad” rations or my “Jap POW camp” rations, meaning that if starvation ever did become a reality, then I would like to have those old rations to look over.
In Stalingrad they were peeling off the wall paper for the old paste, and in the Japanese POW camps, our men were eating things that were way past rotten and insect infested, like long ruined and ignored, many years old rice.
Ping.
A good rule of thumb is that unless when opened they smell bad, rancid or moldy, they are probably fit for human consumption. However, cooking may be a different thing altogether.
Beans are problematic this way, because they will dry out and are very hard to soften, and the fast way to prepare them is to grind them first on a grinding stone. This also works with dried corn, mesquite pods, things like that.
