The group includes clams, cockles, oysters, and mussels. In the context of European food hygiene legislation, the term definition as "'Bivalve molluscs' means filter-feeding lamellibranch molluscs".
Biotoxin Naturally occurring poisonous chemical compound produced by some types of marine algae. Filter-feeding bivalve shellfish can accumulate these toxins from naturally occurring microscopic algae. These algae are periodically present in the water column and become available to the shellfish as part of their diet. The consumption of contaminated shellfish can pose health risks to the consumer as well as economic risks to the shellfish industry. In the European Union (including the UK) there are currently three major shellfish biotoxin groups that can be detected in shellfish and are subject to statutory testing to protect human health. These are: Paralytic Shellfish Poisoning (PSP) toxins; Lipophilic toxins, including those responsible for Diarrhetic Shellfish Poisoning (DSP); Amnesic Shellfish Poisoning (ASP) toxins.
