    but I have long worried about the fact they are bottom feeders in shallow waters - the perfect setup, it seems to me, for ingesting lots and lots of heavy metals, pesticide residues, and other assorted toxins.  

    Katrina damage aside, any good sources on the relative measurements of such toxins in shrimp vis-a-vis other seafoods?

      one thing going for shrimp in this case is that they are primarily scavengers, not filter feeders. So they do not concentrate toxins as efficiently. Also, most shrimp fishing is done off shore rather than in estuaries, which tend to concentrate more heavy metals in the sand and mud.

        So actually molluscs, as filter feeders, would be more logical targets re this concern.
