Abstract:

Shellfish biotoxin closure zones in Puget Sound and Washington coastal areas. Updated on 5/11/2012.

Purpose:

To define areas of marine waters that are managed distinctly for shellfish biotoxin closures. These areas are used to communicate closures to the general public. The areas also support the Internet biotoxin bulletin application at <http://ww4.doh.wa.gov/gis/biotoxin.htm>

Supplemental_Information:

The DOH Biotoxin Program performs year-round monitoring of Paralytic Shellfish Poison (PSP, also known as "red tide"), and Amnesic Shellfish Poison (ASP, or domoic acid) in molluscan shellfish. The term "red tide" is a misnomer...paralytic shellfish poison and domoic acid poison are rarely associated with a red tinge to the water. Both PSP and domoic acid can be present in large amounts when the water appears clear. Reddish coloration of the water is more commonly associated with non-toxic organisms. Biotoxins are caused by microscopic toxin-producing algae that naturally occur in marine waters, normally in amounts too small to be harmful. However, a combination of warm temperatures, sunlight, and nutrient-rich waters can cause rapid plankton reproduction, or "blooms". Molluscan shellfish (those that have a hinged shell, such as clams, mussels, oysters, geoduck, etc.) are filter feeders and ingest the algae into their systems, where toxins concentrate. Paralytic shellfish poison is caused by the phytoplankton Alexandrium catenella; domoic acid poison is caused by the dinoflagellate Pseudo-nitzschia pungens. It is important to note that cooking does not remove these toxins from shellfish. Cooking will kill the organisms, but the toxin remains.
