I am doing food rotation, I am eating that stuff actually.
In war I ate lot of stuff that are clearly expired, some of that did not even had any markings on it, I ate it. Yea, several times I had stomach problems but I did not die from that.
All kind of weird stuff was coming in some period and trough the different channels in country, some as a international help, some as a smuggled garbage.
When you open the can without markings, so you do not have clue what is inside, then you smell it, and at the end if you are really hungry you just eat it.
We joked many times about “what we eating now?” topic.
