I keep them in the fridge no longer than the day after I purchase them. Preferably, I buy them the same day I am going to cook them. But if you are buying from a reputable fishmonger, they should be able to advise you.

added over 2 years agoI think the question is - are they still alive? They usually open a bit when you leave them alone - tap them - if they close back up they are alive and OK, if they don't they are dead and you need to chuck them
I always use them the same day, as I am touchy about seafood. Industry says "a few days" if stored correctly. See http://www.discovermussels...

added over 2 years agoI agree with everyone. Mussels are more fragile than oysters and hardshell clams. If you are somewhere where you can buy them on the day you are eating them, that's what to do. If that's impossible, putting them on top of--not in--ice is okay. But regardless, toss any that won't close or have cracked shells.

I don't buy them if I am not going to serve them the same day. I am like that about any mollusk or shellfish in its shell. The animal needs to be alive when you cook it.

added over 2 years agoWhile I basically agree with you ChefJune, I think your advice is most important for mussels. Oysters are a completely different story. They have much thicker shells and the advantage of one side being more rounded than the other. Packed round side down, they survive pretty well. Even in the 1800s, growers on the East Coast packed them up and shipped them inland. Knowing that, I wouldn't mind keeping oysters on ice for a couple days if I lived somewhere that I couldn't get them on the day I wanted to eat them.

added over 2 years agoI just remembered another mussel-buying point. While it's my preference to know and love my fishmonger, some people don't have access to a great one. My brother, would lives inland, buys his mussels at Costco. They come in bags identifying their source and the date that they were pulled from the water. I've had them and they're really fresh.
