Me too that's why the concern when I read that post about illness from local fish.

To The_Lurker, I haven't had mussels since severe illness aboard a cruise. Many sick but only those who ate mussels and the cruise line tried to convince us it was a virus.
Although I've not eaten them on SXM I've heard of no problems because they come from colder waters than SXM. There's a saying: eat mussels only in month that contain the letter R.
