How long will a can of food last

How long will a can of food last?

The USDA will tell you high-acid canned foods, like tomatoes and citrus fruits will keep for up to 1½ years, and low-acid canned foods like vegetables, meat, and fish will last for up to 5 years.

But the truth is they can last much longer if stored properly and are free of any damage such as dents or bulging.

Canned foods are sterile, so they do not host bacteria, but eventually, the taste and texture of the food will deteriorate.

Case in point, a 40‐yr old can of sweet corn found aboard the sunken U.S.S. Monitor, was opened in 1974 and the nutrient content of the canned corn compared favorably with reported values, except for lower amounts of ascorbic acid. Meaning you could eat it. 

Now that will not be the case for all can foods, but the point is they will last a very long time. The best way to tell if a can is bad is by looking for bulging, which would indicate the food inside is terrible. If no damage is seen, you should open it and inspect the food yourself.

I don’t recommend keeping your can food longer than five years, but if push comes to shove during the apocalypse and you find some old cans, don’t pass them by. There is a good chance they’re still edible.

Note – “Use-By” or “Best Buy” labels on foods are for consumers as a directive of the date by which the product should be eaten for the best quality, not because the item will make you sick if eaten after that date. However, after that date, product quality is likely to go down.

The “Sell-By” labels are for retailers and inform them of the date by which a product should be sold or removed from their shelves. This does not mean the product is unsafe to consume after that date.

How much food can you put in a food grade bucket

In general, five-gallon food-grade buckets can hold:

37 pounds of wheat

33 pounds of cornmeal

33 pounds of flour

36 pounds of rice

35 pounds of dried beans

35 pounds of sugar

37 pounds of whole corn

21 pounds of rolled oats

21 pounds of macaroni

29 pound of spaghetti

Density, size, and shape will determine the exact amount, but at least you have a good idea to go by for whatever you want to store in them.

Food storage, a lifesaver during disasters

Food storage can seem overwhelming, especially when you’re trying to store a month’s worth per person. That’s 2000 calories per person per day. Luckily we have options for helping us reach that goal

Grocery Stores

The food from grocery stores can be stored in its original packaging on a shelf, allowing you to rotate your supplies easily. However, the food in your refrigerator or freezer will need to have a backup generator ready to go if the power goes out.

Survival Food Companies

Survival food companies commonly dehydrated or freeze-dried their products and package them in sealed protective containers that you can store for years; some are even stackable.

Our Gardens

Food from our gardens or orchards can be stored in a variety of ways:

In canning jars. Canning is an important, safe method for preserving and storing food. The canning process involves placing foods in jars or similar containers and heating them to a temperature that destroys micro-organisms. During this heating process, air is driven out of the jar. As it cools, a vacuum seal is formed. There are two safe ways of canning food, the boiling water bath method, and the pressure canner method.

In a root cellar. Storing food in a root cellar is done by paying close attention to your crop varieties, your timing for harvest, and the best storage conditions for each type of fruit or vegetable. Generally, you’ll have food that stores well in a cold, damp environment and food that needs slightly warmer, drier conditions.

In a spring house. If you have a spring or stream on your property, a springhouse could be used to store some foods. It is made from a small building, usually of a single room, constructed over a spring to keep food and liquids cool. The water from the spring or stream maintains a constant cool temperature inside the spring house throughout the year. Food that would otherwise spoil, such as meat, fruit, or dairy products, could be kept there to increase your food storage.

In seed form. While storing food as seeds will not provide you with food right away, It can be a lifesaver during a long-term disaster lasting months or years.

No matter where you get your food, you can increase the lifespan of some of it by storing it in vacuum-sealed bags or mylar bags.
