In the Waste Not, Want Not Challenge the plan is to use down my stockpile that I have collected over the past few years. There are a number of areas that are covered in this challenge.

Having found a few cans that I didnt want to open, because they didnt past my safety check when I looked at them.

Please first of all note some of my cans are well past their use by dates so I am going on look of the can and look of stuff inside it when opened. If it looks like any way different than a new can then it failed the test. My health and that of my pets are well more important than a few cents saved.

So Rule number one here is - If it is not safe to use then dont. Never use dented or leaking or blown cans or if the product doesnt look right or smell right in anyway. Still up to now you havent tasted it so also if taste is wrong too! The more different ingredients in the can the more closer to the use by date it needs to be.
Rule two - Only buy want you will use and in quantities that you will use.
Rule three - Know what you can do with it before you buy large quantities of anything. If it food have at least 5 different recipes or ways of using it up your sleeve.
