How can you tell if canned goods are bad, not good for consumption?
Ones I have don't have expiration dates.
I recall long ago reading about the cans "bulging" being a bad sign, but that isn't good enough in my opinion.
There's gotta be some effective way to determine its freshness. I'm thinking write the date of purchase with a sharpie on the label, but then how long can you wait to use it?
