I had a friend who passed away that was a food scientist. One thing we talked about was canned food. She mentioned an on-going project about canned food. The last time we talked, they had opened and tested some food from cans that were kept in a temperature and humidity controlled environment for 60 years. The food inside was still safe to eat, though there were some color and taste changes. Her take away was that the research was showing as long as the can was not damaged and kept cool, the food would last a very long time. Rust on the can and other damage would cause micro-holes to let oxygen in and then it's game over.

So if MP stores were canned and the climate controls working, canned food might taste a bit off, but you won't die from it.
