Shellfish poisoning

There are four syndromes called shellfish poisoning, which share some common features and are primarily associated with bivalve molluscs (such as mussels, clams, oysters and scallops). These shellfish are filter feeders and, therefore, accumulate toxins produced by microscopic algae, such as dinoflagellates and diatoms, and cyanobacteria.

Syndromes
The syndromes are:
 * Amnesic shellfish poisoning (ASP)
 * Diarrheal shellfish poisoning (DSP)
 * Neurotoxic shellfish poisoning (NSP)
 * Paralytic shellfish poisoning (PSP)
