McCormick, the largest spice manufacturer in the world, is issued a warning to customers.
The company explained how to tell if your spices are too old.
If your spices are in a rectangular tin or packaged in Baltimore, your seasoning has been around for a quarter of a century.
If you've got old spices it might be in your best interest to not use them. When spices age, they lose their flavor so old spices are pretty pointless.
McCormick recommends making sure your spices have a strong aroma and taste, so you should replace them every three years.
