Some of the survival food companies' cans have expiration dates reading "JAN 2046", give or take a couple years if stored properly so we're looking at LEAST 3 decades on some of the brands such as 'Daily Bread' or 'Mountain House' where the oxygen is removed from the food for long term storage.

My long term food is from Walton Feed and most of it is good for 20-25 years - hermetically sealed without oxygen.
