How long past best by date is old bay seasoning good?

Old Bay seasoning can typically remain safe to use for up to 1-2 years past its best by date if stored properly in a cool, dry place. While it may still be safe to consume, its flavor and potency may diminish over time. It’s best to check for any changes in aroma or appearance before use. For optimal flavor, it's recommended to replace spices and seasonings every 1-2 years.
