Are containers of egg whites good past date if unopened and for how long?

Unopened containers of liquid egg whites can generally be safe to consume for a short period past the expiration date if stored properly in the refrigerator. However, the quality may decline, affecting taste and texture. It's advisable to check for any off smells, discoloration, or separation before use. If in doubt, it's best to err on the side of caution and discard the product.
