How to Store Fresh Mussels Safely
Keep your shellfish fresh and safe for the perfect seafood feast.
Fresh mussels last about 1–2 days in the refrigerator when kept properly in their shells or on ice.
Fresh mussels are a delicacy, but because they are highly perishable, they require careful handling to maintain quality and safety. When you purchase fresh-mussels, they should be kept chilled immediately. Unlike some other seafood, mussels have a very short window of peak freshness once removed from the water or their original airtight packaging. Proper refrigeration ensures that the meat remains firm and flavorful for your next meal. Because these are considered safety-critical, it is essential to monitor them closely; if they do not remain tightly closed or show signs of distress, they should be discarded immediately.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
How long can I keep fresh mussels in the refrigerator?
Fresh mussels last about 1–2 days in the refrigerator when kept properly in their shells or on ice.
How can I tell if fresh mussels are still good?
Fresh mussels should be tightly closed. If they are open, tap them; they should close. If they remain open or smell strongly of ammonia, toss them.
Can I freeze fresh mussels to extend their life?
While possible, freezing changes the texture and makes it harder to clean. It is best to use them within 2 days of purchase.
Does cooking spoiled fresh mussels make them safe?
No. Sage's Verdict: Cooking does not neutralize the toxins or bacteria present in seafood that has already begun to spoil.
Keep those shells tight and your fridge cold! Fresh-mussels are best enjoyed when they're at their peak.
