Canned food is a great way to store emergency food that can easily be incorporated into your normal diet. With an expiration date of a few years in the future, canned food can last even longer in your underground bunker. According to the Preserved Foods Alliance, canned foods stored at moderate temperatures (75 F or lower) have a shelf life of approximately two years from the date they were processed. After that, you can expect changes in quality, color and texture, but the nutritional value can last “much longer than two years”.
In terms of edibility, canned food is a long-term game.Most experts don't believe in expiration dates. If you're canning your own food at home, you should know that these foods will last up to a year on the shelf. Don't let the date on non-perishable food products discourage you from stocking up on a good supply of commercial canned goods. The Preserved Food Alliance cites 100-year-old canned food recovered from sunken ships that proved to be microbiologically safe, even though it had lost most of its fresh smell and appearance.The Food and Drug Administration doesn't even require canned foods to be labeled with expiration dates because they last so long - think decades! So the question remains, how long after the expiration date can canned food be eaten? One year, five years, ten years? In fact, there have been cases where canned food has survived a hundred years without any type of microbial growth.The vast majority of food date labels, including “sell first”, “use sooner” and “best if used sooner” labels, are suggestions from food manufacturers for maximum freshness and flavor, rather than indicators of food safety or health problems.
Canned foods are a fantastic way to store emergency food that can easily be changed into your normal diet.
