30 years ago, I took some K-Rats on a school outing. My father had rescued a case of them when the Department of Civil Defense was rotating its supplies -- the case was dated (best as I recall) 1946 or 1948 or something like that. None of the cans were rusted or bulging. The P-38 worked like a charm of course. The spaghetti itself was bland and a rather disgusting texture since I hadn't bothered to heat the can before opening it -- in fact, after seeing the can, a schoolmate offered me his lunch if I'd throw it out. The fruit cocktail was marvelous. I survived eating both.

Think about what the item is and what it would take to make it degrade. Yogurt is past its date but has been kept sealed and cool? Just what do you think would have caused it to spoil? Do you think sugar or vinegar will go bad?

We live in wimpy weenie times.
