Expiration & Storage Tips
When does mussel expire?
Mussels can take on a variety of expiration timelines depending on how they are stored. If they are unopened and kept in the seafood counter bag, they generally last approximately 2-3 days when stored in the refrigerator at or below 4 degrees Celsius (39 degrees Fahrenheit). Compared to the printed date on their package, mussels should never be consumed after their 'Use By' date. Once mussels have been cooked, they should be consumed immediately, but any leftovers can be kept in the refrigerator for up to two days. If they are frozen, they may last up to three months but their quality will decrease after the first month.
How do you tell if mussel is bad?
Determining whether mussels are bad or not is a simple task even if you're new in the kitchen. First, you should smell them. Fresh mussels will have a briny sea smell (similar to the ocean), but they should not smell fishy or foul. If they do, it's possible they've gone bad and should not be eaten. Another way to check is to observe the shells of the mussels. If the shells are broken or damaged in any way, it's best to throw them out. Lastly, before cooking, if any mussels do not close when tapped lightly, they are dead and should not be eaten. After cooking, any mussels that do not open should be discarded.
Tips for storing mussel to extend shelf life
• Always store your mussels in the refrigerator as soon as possible after purchase.
• Mussels should be stored in a bowl covered loosely with damp paper towel or cloth to keep them moist.
• Never store mussels in water or a sealed container - they breathe and will suffocate.
• Leftover cooked mussels can be stored in the fridge, but be sure to consume them within 2 days and never reheat them more than once.
• If you need to store mussels for longer periods, you may choose to freeze them. Cook mussels prior to freezing, and once cooked, cool quickly, wrap individually or place in a freezer bag before storing in the freezer. Defrost overnight in the refrigerator before enjoying.
