How long do canned black beans last?

Unopened canned black beans typically have a shelf life of 1 to 2 years from the date of canning, as long as they are stored in a cool, dark pantry or cupboard. Once opened, canned black beans can be refrigerated in their liquid for up to 3 to 4 days, or tightly covered in a separate airtight container for up to 5 to 7 days. It's important to always discard any spoiled canned beans that show signs of spoilage, such as bulging or leaking cans, rancid smells, or unusual discoloration.
