50 year old bomb shelter

[BDG]

It is the inside of the tin that counts, not the outside.Tins are lined, so as long as the lining has not deteriorated or been pentrated, it would be fine. If a breech has occurred, you should be able to tell by staining to the food to some extent.

If you are starving and have nothing else, no reason not to eat them.

It does however show the importance of proper storage rather than ramming things in a drawer where they can be exposed to airborne dirt that will trap moisture against the can.
