I picked up 5lbs of mussels today for dinner and didn’t realize until I got home that they never put them on ice for transport. It’s was about 1.5 hours between purchase and the time I put them in my fridge. They were in an air conditioned vehicle the whole time except for about 20 minutes when I ran into the grocery store. The car did heat up then.
When I got home and realized there was no ice I called the market for advise and they said toss them, they probably died. In an attempt to avoid driving almost an hour to get more I dropped them in water to see if they floated or sunk and I saw a number of them swimming and moving. I assumed they weren’t dead at that point and went to wash each individually to inspect them. The vast majority were tightly closed, with only about 20 mussels of the 5 lbs slightly open. There was also one middle that was wide open but snapped shut when i put water on it. (Again, I’m assuming that’s definitely alive.)
After finding the vast majority still tightly closed, I called the market back and they were very unhelpful. The manager said she sticks by her original statement that they are probably dead, but if they were tightly closed they would probably be ok.
So, I need advise, I don’t want to make our dinner guests sick, but I’m also hesitant to make the 1 hour drive (one way) to pick up more mussels. Should I just chalk it up to a loss and do a different dinner? Or am I totally safe to serve them????
