You might be surprised to learn that canned food has a shelf life of years—and sometimes decades—beyond the printed date on the label. The “sell by,” “use by,” and “best before” dates on canned goods can be confusing. Here’s what you need to know about the shelf life of canned foods.
Canned foods are safe indefinitely as long as they are not exposed to freezing temperatures, and their seals remain intact. But for best quality, most cans should be used within two years from the time they were sealed at the factory.
The United States Department of Agriculture (USDA) advises tossing out canned food once it hits its third birthday. But that’s just a general guideline, says William Shewfelt, director of communications at the Can Manufacturers Institute (CMI).
Here’s what you need to know
Canned food can be a great pantry staple, but it’s important to know how long it will last and when it’s time to toss it. Here’s a quick guide to help you out.

So, how can you tell if your canned food has gone bad? The best way is to use your senses. start by looking at the can. If it’s bulging or dented, toss it. Then, give it a sniff. If the contents smell bad or off, don’t eat them. Finally, give the food a taste. If it doesn’t taste right, don’t eat it.
If you’re ever in doubt, err on the side of caution and throw the can away. It’s better to be safe than sorry!
The shelf life of canned food
Canned food has a shelf life of at least two years from the date of production. After opening the can, it is recommended to consume the food within a few days.
The process of canning food was invented in 1809 by French confectioner Nicolas Appert. This method of food preservation involves sealing food in an airtight container, such as a glass jar or tin can, and heating it to a high temperature to kill bacteria.
Canned foods are a convenient and affordable option for busy families. However, it is important to be aware of the potential risks associated with consuming expired canned goods.
One of the main concerns with consuming expired canned food is the risk of botulism poisoning. This potentially fatal illness is caused by Clostridium botulinum, a type of bacteria that thrives in poorly ventilated and oxygen-deprived environments, such as sealed cans. When these bacteria come into contact with food, they produce a toxin that can cause paralysis and death if consumed.
While the risk of contracting botulism from canned goods is low, it is still important to take precautions when handling and storing canned foods. Canned foods should be stored in a cool, dry place away from direct sunlight. If the can is damaged or swollen, do not consume the contents. If you are unsure whether or not a particular can of food has gone bad, it is best to err on the side of caution and throw it out.
How to tell if canned food has gone bad
Canned foods are a convenient and shelf-stable option, but even they can go bad. Here’s how to tell if canned food has gone bad, plus advice on how to properly store canned goods.
There are several ways to tell if canned food has gone bad. The most obvious sign is visible mold or chunks that look different from the rest of the food. You may also notice a change in color or texture, or the food may emit an off odor. If any of these signs are present, throw the can out.
Another way to tell if canned food has gone bad is by checking the can itself for signs of damage, such as rusting, leaking or bulging. If the can looks damaged, it’s best to err on the side of caution and throw it away.
If you’re not sure if canned food has gone bad, it’s always best to err on the side of caution and throw it away. When in doubt, throw it out!

-Store canned food in a cool, dry place.
-Avoid storing canned food in direct sunlight or near a heat source.
-Check canned food for dents, rust, or leaks before purchasing or using.

Canning your own food
Food preservation is an ancient art that has seen a resurgence in popularity in recent years. More and more people are interested in canning their own food for a number of reasons, including the desire to eat more healthy, locally sourced food, or the challenge of taking on a new DIY project.
If you’re new to canning, you might be wondering how long canned foods last. The answer is that canned food does not technically expire, but it can go bad. Here’s what you need to know about the shelf life of canned food.
Canned foods are sealed tightly and cooked in order to kill bacteria and other microbes that can cause spoilage. This makes them safe to eat without further cooking or preparation. However, canned foods are not sterile, and over time bacteria can grow and spoil the food.
The National Center for Home Food Preservation recommends eating canned food within two years of canning for best quality. However, canned food is often safe to eat years after this point as long as the can itself is in good condition and has not been damaged or dented.
To extend the shelf life of your canned foods, store them in a cool, dark place such as a pantry or cupboard. Canned foods stored in a warm place or exposed to light may lose some of their flavor or nutrition over time.
The benefits of canned food
Canned food has come a long way since its humble beginnings in the early 1800s. Nowadays, canned food is a common sight in pantries across the globe, and for good reason. Canned food is an easy and convenient way to enjoy a variety of foods, from fruits and vegetables to soups and sauces.
Canned food also has a number of benefits that make it a worthy addition to your pantry. For one, canned food has a longer shelf life than fresh food, so you can always have a tasty meal on hand. Canned food is also often more affordable than fresh or frozen options, making it a budget-friendly option for families.
So, what about expiration dates? Does canned food expire? Here’s what you need to know:
While canned food doesn’t technically expire, it can become unsafe to eat after a certain amount of time. Most canned foods will be safe to eat for at least two years from the date of purchase, though some may last even longer. Once opened, canned goods should be consumed within a few days or transferred to an airtight container for storage.
If you’re ever unsure about whether or not a particular can of food is still safe to eat, it’s best to err on the side of caution and throw it out. Better safe than sorry!
