Can Mustard Go Bad In Fridge?
Yes, mustard can go bad in the fridge. Mustard typically has a shelf life of around 1-2 years if stored properly in a cool, dry place. However, once opened, it should be stored in the fridge and will usually last for up to 6 months. If there is any sign of mold, unpleasant odor, or discoloration, it is best to discard the mustard.
