Hissing Sound Upon Opening: If you hear a loud hissing sound when you open a can (and it’s not due to natural vacuum pressure), it could indicate that gases have built up inside due to spoilage.
Final Thoughts
In summary, “best by” dates on canned foods are not strict expiration dates, but rather suggestions for when the product will be at its peak quality. Canned goods like corn, green beans, and tuna can often be used safely for an extended period beyond these dates—sometimes even years—if they are stored correctly and show no signs of damage or spoilage. When in doubt, always inspect the can and its contents thoroughly before using. By understanding how to properly interpret “best by” dates and store canned goods, you can reduce food waste, save money, and enjoy your pantry staples long after their labeled dates.
By following these guidelines and using your best judgment, you can safely extend the shelf life of your canned foods and get the most out of your pantry essentials.
