Smoked salmon might not seem like survival food to those who normally buy MREs by the case, but if you've ever bought some of the smoked and vacuum packed fish you may have noticed that it typically has a "good through" or "best before" date that's three to five years in the future.

So while this might not be the most cost-effective way to stock your emergency stores, it definitely will break up a week of roast beef or spaghetti MREs.
