How long do Costco precooked ribs last in the fridge?

Quick Scoop

Costco precooked ribs usually last about 3 to 4 days in the fridge if they stay properly refrigerated and unopened. Some Costco shoppers report the label best-before date can be as short as two days from purchase, so the package date matters too.
