How Long Will my Stored Food Last?

You are doing a great job collecting all sorts of foods for your doomsday storage, but you have always been concerned just how long stored food will all last. Your plan is to keep your family fed, not make them sick. I have done some research and have found the answers for you. I hope this helps.

Canned Foods

As you probably suspected, best by dates don’t mean much. These dates are voluntarily placed on products to give a general guideline for how long it will be at its best quality. After this date, you will see loss of color, flavor, etc. Most manufacturers will back their products 2-3 years (depending on the product) after canning which gives you some time at the very least. Some people will insist that canned foods are more likely to last 15-20 years. In 1938, some canned foods were found from an 1820 expedition to the north pole. The cans were 118 years old and the cat who ate the canned meat didn’t complain and suffered no ill effects.


Recommendations for some common foods that I have found are; canned meats (2-5 years or the expiration date on the can), baby food (1 year or the expiration date on the can), tomato sauce (1 year), canned fruits (2-5 years), fruit juice (6 months to a year), canned vegetables and baked beans (1-2 years), spaghetti sauce and soups (1 year or the expiration date).


Home canned foods should be find for one year if they are stored in a dry cool place. If they are kept in a warm place or near indirect sunlight, they might lose some of their quality, flavor, or color. If they are in a damp area, the lids may corrode and the food will spoil. Also, make sure that the canning process was followed.


Botulism is also a danger for canned foods, especially home canned foods or rusty cans. It is a potentially life threatening bacteria but can be killed by boiling the food for 10-20 minutes.


Dried Foods

Beef Jerky and dried fruits can last around a year if they are in their original packaging. If you made them yourself, make sure they are properly dehydrated and placed into vacuum sealed bags. Vacuum sealed jerky and fruits should last around a year. If you are just keeping them in a zipper bag or something like that, probably not much more than 15 days. Freezing will make them last longer.



An MRE typically lasts 5 years. Storage temperature is important for an MRE. The lower the temperature, the longer it will last. In temperatures at or below 60 degrees Fahrenheit (15 degrees Celsius), an MRE can last up to 10 years. At a temperature of around 120 degrees Fahrenheit (50 degrees Celsius), an MRE will only last 1 month. An MRE will lose quality and shelf life if stored improperly. Probably not a good thing to keep in the bug-out-bag that you keep in your car all summer.


Freeze Dried Food

Freeze dried foods have the advantage of having very little water or air in them to cause spoilage. The freeze drying process typically removes most of the moisture from the food and oxygen from the packaging. Unopened Cans of freeze dried foods should last around 25 years and pouches last around 7 years. Freeze dried foods can last between 1-2 years after opening as long as minimal oxygen and moisture is introduced into the package. make sure they are kept in an air tight container after opening.


The times suggested in this article are just guidelines for your food storage plan. It assumes that these packaged foods are kept in a dry, cool place, out of the sun, and are kept free of damage. As a general practice, you should throw it away is it smells, looks, or tastes bad.

    I heard on the radio this morning that the USDA is saying that the expiration dates placed on foods are not regulated. In other words, food companies pick out a date themselves.

    The USDA also said that most people sickened by foods are not sickened because of the expiration date, but by things that were already in the food when it was packages, things that leeched in through the packaging, or things that were on the counters when the food was placed on the counters.

    I will try to find more on this.

    Another comment that I have heard people talking about, but have not confirmed is that the cans with pull top lids apparently have a much shorter life than the cans that do not have pull top lids.

    I take exception, but not umbrage at your comment that home canned foods should be fine for a year. I am currently eating meat; beef, pork, tuna, chicken and ham that I canned in 2008. I am rotating out and replacing. The food is excellent with no appearent degradation in quality or apperence. I cant speak to the loss of nutritional value but it sure tastes good. I would put my home canned foods up against commercial any day. I would much rather long term store in a glass jar than cans. I absolutly agrre that the most importent factor in long term storage is a cool, dry enviroment.

      I agree. If you store your food properly, it can last quite a bit longer than one year. Those were just recommendations.

      I suggest if you are eating foods that are older than one year that you check it for freshness before you consume it.

    This is a very helpful article. I bet a lot of people have expired food in their pantries and emergency kits. It is very important to keep up on your doomsday preparation.

    This is excellent advice.
    In general, the packaging on commercial foods isn't wrong – keep everything in a cool, dark place, and it'll all last longer.
    Also remember that freeze-dried foods needs water for preparation, which may or may not be an issue in your shelter. If you have plenty of water (e.g. a hand pump to the water table in the shelter) then you're set. If you have to ration water, take that into consideration when choosing foods.

      Good point. And more specifically, you need HOT water. MRE is good because most of them come with a heater, but they also take water to activate the heater.

    I follow your blog for preparedness tips since I live in South Florida {insert face eating joke here} and Hurricanes are always on my mind.
    At the end of Hurricane season, I donate those items that I have put aside for our Hurricane kit. My kids schools usually run a food drive at that time of year. That way I don't worry about expiration dates on the canned goods.
