For canned beans, whose quality shelf life might be 2-5 years, what is often true about their safety aspect?

Answer

The safety aspect might extend almost indefinitely provided the seal remains intact.

For properly sealed shelf-stable items, the quality (texture, flavor) degrades over time, but the safety margin can last much longer if contamination, such as botulism, is prevented by an intact seal.
