Great post Kartographer. I just bought around $1000 or so of canned food over the last month with the longest expiration dates. This is very good news for me at least, during a very dark time. Will buy some more in addition to other efforts. Buying the extra vitamins also makes sense, which I have also done.
Don’t worry about expiration dates on canned food. Those are just put on to keep the gubmint happy. Truth is canned food will last longer than you will. It may lose some flavor and color after a few decades, but will still be edible. They recently found a 6 lb can of beef from before the civil war, opened it up and fed it to test rats. The rats were fine.
