Can You Get Sick From Eating Expired Mustard?
You may not get sick from eating expired mustard, but the quality and taste of the mustard may deteriorate. Mustard is a fermented food and it has a high acidity that makes it less prone to spoilage, but over time, it can lose its flavor and texture. It can also develop mold or off-odors and cause food poisoning.
While mustard eventually goes bad, most mustards last 2-3 years past their “best-by” date, but this is not the only indicator of freshness. Thanks to vinegar and flavorings, mustards stay fresh at least a year after they are opened. At room temperature, mustard will retain its quality for approximately 1-2 months, and when kept refrigerated, should remain good for approximately one year.
An opened can of mustard should retain quality between 6 to 12 months if left in the refrigerator, and around one or two months if kept at room temperature. As long as jar is not opened, mustard keeps its quality for years; once opened, it keeps best from 6 months to one year in the refrigerator. The best way to store unopened mustard is with it sealed tightly, to prevent any other bacteria from getting into the lid, and at room temperature. As long as mustard is not opened, you will easily be able to keep it for one to two years after the labeled expiration date.

Cracks on the mustard surface are an indication that the quality has degraded to a point where it is no longer worth saving mustard.
