Walk down any grocery aisle and you’ll see cans neatly lined up, each stamped with a small date. For many of us—especially seniors—those labels can cause hesitation.
You might ask yourself:
“Is this can of corn still safe?”
“Should I throw out these green beans because the date passed last month?”
“Can I trust this tuna?”
It’s easy to feel uncertain. We’ve all heard warnings about expiration dates, but the truth is: most of these dates are guidelines for quality, not safety. Understanding the difference can help older adults save money, reduce food waste, and enjoy safe, nourishing meals—long after the printed date has passed.
This guide explains what those dates really mean, how long canned foods actually last, and how to store your pantry staples safely and effectively.
✅ What “Best By” Really Means
Let’s clear up the biggest misunderstanding first:
A “Best By” date is not an expiration date.
It’s simply the manufacturer’s estimate of how long the product will maintain its best flavor and texture. After that date, the quality may slowly decline, but the food is still safe to eat—as long as the can is intact and stored properly.
Think of it like a loaf of bread. It may taste best when it’s fresh, but even a few days later, it’s still edible. Canned foods are the same—just on a much longer timeline.
🥫 The Long Shelf Life of Canned Foods
Canned goods are among the safest, most durable pantry items. They’re sealed tightly, heat-processed to kill bacteria, and designed to last. When stored correctly, many canned foods can remain safe years past their “Best By” date.
Here are some common examples:
Canned Corn
A pantry staple for quick meals, canned corn can last up to 2 years past the “Best By” date when stored in a cool, dry place.
The flavor may change slightly, and the texture might soften, but it remains safe as long as the can isn’t damaged.
Canned Green Beans
Like corn, green beans can last 2 years or more past the printed date.
The taste may be milder over time, but it’s perfectly fine to use in your favorite recipes if the can is in good condition.
Canned Tuna
Tuna is one of the longest-lasting canned foods, often staying good for 3 to 5 years beyond its label date.
Just be sure the can is intact, and inspect it before use.
