  Living with a Shellfish Allergy on MedicineNet.com
If you suffer from a shellfish allergy, strictly avoiding shellfish and food containing shellfish is the only way to prevent a reaction.
If your doctor is able to identify exactly which type of shellfish causes your allergies, then you only need to eliminate that type of shellfish from your diet.
For the majority of shellfish allergy sufferers, however, this is not an option and all shellfish must be avoided.

  US FDA/CFSAN - Bad Bug Book - Various Shellfish-Associated Toxins
Shellfish poisoning is caused by a group of toxins elaborated by planktonic algae (dinoflagellates, in most cases) upon which the shellfish feed.
The 20 toxins responsible for paralytic shellfish poisonings (PSP) are all derivatives of saxitoxin.
Paralytic shellfish poisoning (PSP) is a foodborne illness caused by consumption of shellfish or broth from cooked shellfish that contain either concentrated saxitoxin, an alkaloid neurotoxin, or related compounds.

  EPA-MAIA - Shellfish Closures   (Site not responding. Last check: )
Bivalve shellfish are filter feeders, meaning they pump water through their gills for both respiration and feeding.
Because shellfish are such effective filters of the water, they tend to accumulate whatever pollutants are in the water.
Due to these differences in the calcula- tion of action levels by different states, the fish or shellfish contaminant concentrations in one state’s advisory area may not be the same as another state’s, but in both areas the concentrations would be high enough to cause concern about possible human health risk.
