Possibly even worse! These mussels were not suitable for consumption.
Lot number L73335, product date 24-5-2013, consumption date, or better 'discard date' 28-5-2013. I took pictures of the first 40 mussels on the 4 kg. that we could throw away immediately. After cooking, we were able to throw away 1 in 3. On balance, everything was just thrown away!
The worst thing is that I don't have to come home with mussels for a while.
I see no chance of reacting to Prins & Dingemans. At a previous time, when worms were swimming alongside the oyster, I was told as a culprit: "Well, it is a natural product that can occur!". Not even more information about food safety or just sorry.
