Many shoppers become confused by "Best by" labeling. Many food items, particularly canned foods, will have these dates printed on them. "Best by" dates aren't necessarily the end of the shelf life, either. Rather, they show when the maker thinks the product will be at its best.
You can find out how long you may safely consume canned goods like maize, green beans, and tuna after their "best by" dates in this article.

'Best By' Dates: A Comprehensive Guide
"The "best by" date is just a guideline for when the product is likely to be at its most tasty and fresh, not a guarantee of food safety. So, if you preserve your canned goods correctly, you can eat them even after the "best by" date has gone.

Many people rely on canned maize as an essential pantry staple. Fortunately, canned corn often has a long shelf life beyond its "best by" date. Canned corn has a "best by" date and may be safely eaten for up to 1-2 years beyond that if the can is unbroken and kept in a cool, dry area. But there's a chance that the taste, texture, and quality will degrade with time.
Verify that the corn in the can is safe to eat by looking for bulging, rust, or leaks. You shouldn't use the product if the can is tampered with in any manner.
Vegetables in a Can
Green beans in a can are another staple in most kitchens. You may safely eat these veggies after their "best by" date, just like you can with canned corn. Canned green beans, if kept in the correct way, have a shelf life of one to two years beyond the expiration date. Deterioration in quality, including flavor and texture, is possible over time.
Before using, make sure the can is in good condition. Take precautions and throw out the goods if the can seems broken or compromised.
Tuna in a can

One dietary item that is both adaptable and rich in protein is canned tuna. Cans of tuna have a long shelf life beyond their "best by" date as long as they are stored properly. You may usually eat canned tuna for three to five years after the "best by" date.
But remember that canned tuna might lose some of its quality with time. Before utilizing the can, make sure it is free of damage or degradation. While opening the can, keep an eye out for any changes in smell, texture, or appearance. Do not eat tuna if it has an odd scent, a strange texture, or an unsettling appearance.

Here are some storing methods to make sure your canned foods last as long as possible:
Store canned products in a dry, cool spot out of the reach of children and pets and away from severe heat or cold.
To keep the seals intact, store the cans upright.
Put your most recent canned goods toward the back of the pantry and work your way forward with the oldest.
Cans' seal and safety are at risk if they are dented or otherwise damaged.
You might want to think about putting any extra canned food in a sealed container and storing it in the fridge for a few days.

Ending Remarks
All things considered, the "best by" dates on food cans are more of recommendations for when the item will be at its greatest quality than hard expiry dates. Assuming they are stored properly and don't exhibit any indications of damage or spoiling, canned corn, green beans, and tuna may often be used safely for a considerable amount of time beyond their "best by" dates. If you see any canned food that smells funny, looks weird, or seems spoiled, make your best judgment and throw it out. To get the most out of your canned foods and cut down on food waste, store them correctly and check them often.
