Is unopened cream of mushroom soup safe to use after the "expiration" date on the can or package? Yes, provided it is properly stored and the can is undamaged - commercially packaged cream of mushroom soup will typically carry a "Best By," "Best if Used By," "Best Before", or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the cream of mushroom soup will remain at peak quality.
