Ever wondered about the shelf life of different items in your long term food storage? Sure, you have. Well, let’s look at the shelf life of canned goods, dried foods, and other goods.
Now, if you have freeze dried food that is still in the factory packaging, such as No. 10 cans, then you don’t have to worry. Tests have shown that Mountain House Freeze Dried Food in No. 10 Cans can have a shelf life that exceeds 30 years. However, other foods are different.
For purposes of our discussion, we will assume that the temperature of the storage area is 70 deg F. Also, these are somewhat conservative estimates, meaning safe estimates.
