The Shelf Life of Canned Foods: What You Should KnowCanned food is an essential part of any household pantry, providing long-lasting and convenient storage options. Canned food can last a long time, even up to 10 years if the container is well-maintained. However, it’s essential to know the shelf-life of canned foods and how to prevent spoilage.
Understanding Expiration Dates and Shelf-Stable FoodsThe expiration dates on canned food packaging aren’t always accurate as they indicate the Best By date, which is when the food is at its peak quality. However, shelf-stable foods can usually last beyond their expiration dates if stored correctly. The expiration date is not technically when the food is no longer safe to eat. It’s important to note that the nutritional value, flavor, and texture of the food may deteriorate after the expiration date has passed. However, most canned foods are safe to eat beyond their expiration date as long as the packaging is undamaged and the can doesn’t show signs of damage.
The following are some of the shelf-stable foods that are safe beyond their expiration dates:
- Cereal and Pasta: These foods can last for years beyond their expiration dates if stored in a cool, dry place and in an airtight container.
- Cookies: Cookies can last for several months beyond their expiration dates if stored in an airtight container at room temperature.
Signs of Spoilage: How to Tell if Your Canned Food is Still GoodIt’s essential to inspect your canned food before consuming it, especially if it’s beyond its expiration date. If the packaging is dented, swollen or rusted, it is best to discard the can as it may be contaminated with a harmful bacteria that could cause food poisoning.
Other signs that canned food may be spoiled include bulging, leaking, or a foul odor. Be sure to check the food’s color and texture too. If the food looks or smells odd, it’s best not to eat it. If the can appears to be in good condition and there is no visible evidence of spoilage, it’s safe to open and eat the food. But, when in doubt, it’s best to throw it out.

Food Packaging and Shelf Life: Beyond Best-By DatesProper food packaging is crucial to maximize the shelf-life of canned food. Opt for glass or plastic packaging as they are less likely to develop rust and are unlikely to bulge when the food inside spoils. Metallic cans, if not maintained well, can develop rust that contaminates the food inside, making it unsafe for consumption. The packaging should also be airtight, keeping at bay harmful organisms and other factors that may cause spoilage.
