I just have a question. I recieved frozen, partially frozen and thawed out/cold mysis shrimp yesterday. I fed the sea horses the thawed out shrimp upon arrival and then this morning fed them the refrozen shrimp. I have read here that as long as it doesn not float it should be okay. I called the fishstore that I purchased from, they were closed yesterday. So then I called the PE company. They said that the partially frozen ones are ok to refreeze. No mention of the completely thawed one. This morning, I accidently fed them the refrozen (previously thawed completely out) product! I am stressed and worried today. They did not seem as eager to eat the shrimp this morning as they were last night, they did eat but not with as much enthusiasm as yesterday. Any suggestions/ experience with this?:unsure: I e-mailed the company and PE today. PE sadi that they talked to me yeaterday and it would be fine for the partilly frozen ones but would not comment on the completely frozen product despite two e-mails to them. The store I purchased the products from wrote back and said they willl credit for unthawe dproduct. I am afraid my seahorses and fish will be sick now. What should I look out for?April 30, 2009 at 6:59 am #4786Pete GiwojnaGuest
I’m very sorry to hear about the problem you had with your frozen Mysis. I would not trust frozen Mysis that had thawed during transit, and I feel you should discard any Mysis that was not frozen when it reached you. It is true that tainted Mysis will often float due to the gasses of decomposition once it begins to decay, but thawed Mysis can also be contaminated with bacteria on its surface and sink as usual. It is standard operating procedure to ship frozen Mysis on dry ice so that it does not thaw out en route and it is unfortunate that you might have received a bad batch of Mysis.
The Mysis that was still frozen solid should be safe and clean, but I would be suspicious of any Mysis that was not fully frozen when it arrived, and I would definitely ditch the Mysis that had obviously thawed. You should be entitled to a refund, or a new shipment of Mysis, to replace the dubious Mysis that could possibly have begun to spoil before it reached you.
If your seahorses or other fish have eaten any Mysis that was spoiled or contaminated, it would have a similar effect on them to food poisoning in humans. If so, a mild case would simply put them off their feed temporarily and result in a loss of appetite, just as you might lose your appetite after eating a bit of bad potato salad during a summertime picnic. Most of the time the seahorses will recover without any long-lasting ill effects, just as you or I would after scarfing down some tainted potato salad.
As a precaution, I would fast your seahorses and other fish tomorrow so that they can purge themselves of any suspicious Mysis. Get rid of the dubious Mysis that may have thawed en route and use the well-frozen Mysis that you know is safe to feed them the following day. If they feed normally at that time, you can feel confident that all is well and they are going to be none the worse for wear.
Best wishes with all your fishes, Gidget!
