Supernal:On a recent trip to Long Island, New York, I noticed mussels growing on the jettys there. I wondered if they were safe to eat. I was told by locals that they never ate them, but used them for fish bait. I still wonder, though.
Not a very good idea. Having seen some of these mussels (they are probably the Ribbed variety - Modiolus ?) they are known pesticide accumulators. Long Island has a well known history regarding higher incidences of cancer too. I know divers do collect the Blue variety far offshore though.
