Is there a recommended 'shelf life' for canned food?
I opened a really old (maybe 5-7 years) can of chicken noodle soup and wasn't sure if it was still 'good'. There were no date or information to that end on the can of any sort.
Which got me to thinking about earthquake preparedness. Us Southern Californian folk are 'supposed' to have earthquake supplies on hand. How long can you keep canned goods? Does it matter what's inside the can?
