Regardless of if you are a gourmet chef or if you just microwave frozen meals, chances are you have spices in your house. In fact, based on Census data and a Simmons National Consumer Survey, 300.62 million Americans used seasonings and spices in 2020, and McCormick, the largest spice manufacturer in the world, has a warning for all of them.

In a pair of Facebook posts, the company explained how to tell if your spices are too old... like way too old. Thankfully, it's not very hard to figure it out.
