  1. Hello,

    Usually, I only lurk here, to learn and to find new idea. There seem to
    be quite a few knowledgeable people around, it is a pleasure reading you.

    I have a question about keeping mussels. On Thursday, I bought a (
    vacuum?) sealed pack of mussels at the supermarket. I cooked half of
    them that day, they were fine. The next day, I wanted to cook the other
    half. It was in the now-open package. It turned out all the mussels had
    opened. So I didn't eat them. According the expiration date, they should
    still have been ok (for at that day). I felt sorry that the animals had
    died in vain (and that I couldn't eat them, but the useless deaths
    impressed me more).

    Anyway, my question is: is it normal that they died before the
    expiration date? Is it because the package had been opened? Or should I
    go and tell the supermarket their expiration date wasn't accurate?

    TIA,

    jake

    Live mussels cannot be kept in a sealed container. They need oxygen and will
    die if sealed. Also, a perfectly good mussel can be open - but when
    disturbed they will close. If the mussels really were vacuum sealed then
    they could not have been live, but I have never heard of non-live mussels
    being sold in the shell (unless frozen). I hope this info helps.

    I did not test the open mussels to see if they would close. Darn. I am
    definitely learning here 🙂.

    Their packaging *was* sealed, it was a plastic tub that had a sealed
    lid. There was a little bit of water in it, too, so it is feasible that
    they were getting osygen. I suspect it is specialized packaging, it is
    used in all shops here (The Nehterlands).

  4. It is common to buy mussells here(Miami,Fl.) that are not alive. They
    are sold in the supermarket and are on ice. You're mussells would have
    probably been fine to consume. When in doubt, use your nose...seafood
    has a "special" way of telling you when it's gone bad.

    Peter, while at Costco yesterday looking in a 'cold' case (not frozen case
    or cabinet), I saw for the first time a package of vacuum sealed mussels (in
    shells). DH does like mussels, but I didn't get a chance to point them out
    to him. But they had a window in the package and they didn't look too
    appetizing, being surrounded by some opaque type of creamy liquid. Yikes!

    They're cooked and packed in a weak "garlic-butter sauce." I tried them
    a couple days ago and I must say they're not to my liking. The sauce is
    thin and weak with not much garlic to it. That's not terrible. The part
    I didn't like was that there were bits of broken shells in the package,
    but they weren't obvious. Small pieces. We dumped them over pasta and
    ended up adding butter and seasonings. And watching out plates to make
    sure we didn't get tiny fragments of shell.

    We don't as a matter of course buy cooked seafood, and this was an
    experiment. Nope.

    They had their periodic seafood display out on the floor with some
    enormous scallops and shrimp, snow crab legs and whole dungeness crabs.
    Whole salmon. Bags of mussels. We didn't buy any because we were
    experimenting. Oh, well...

    Thanks, you saved us some money!!!! (I didn't price them, but I know they
    weren't for free.)
    We've bought at various times most of the items on the seafood display. I'm
    sure (and have seen them do this sometimes) that they just place
    fresh-frozen seafood out on the ice and they semi-thaw there. The crab is
    especially watery to me done this way, as well as the scallops. I have
    found the frozen (in the case) sea scallops from New Bedford, Mass. very
    good; there is a sweetness to them.

    I have bought their seafood in the displays and found them to be better
    than average around here. All West Coast crabs in the east are cooked
    before they're shipped here unless they're still alive. And I've only
    seen dungeness crabs live here (I'd love to see snow crabs and king
    crabs in a store, 4-feet across and [censored]). <LOL>.

    We've bought clams and mussels and they were always good. Scallops,
    likewise. Couple whole, headed salmon were fine. Only once bought
    lobster tails and decided I didn't like them - tough. Generally, I like
    Costco for food shopping in general. Their meats are far and away the
    best around. Best quality and prices, but, yes, ya gotta buy a honking
    great amount to best benefit.

    Yep, re the amount. Last night we brought home a large package of Italian
    Hot Sausages and cooked them all and put them in individual packages in the
    freezer. And some kilbasse (sp?) I never hesitate to buy their cheeses;
    when I go to Martin's I find their cheeses are several dollars more per
    pound for the same thing. I've not bought any of the lobster tails at
    Costco.

    If you Google on

    mussels storage

    you will find a number of useful references. For open mussels, tap on
    the shell to see if they close (alive). If they don't (dead), discard.
