OLYMPIA, WA — State health officials issued a warning against consuming certain shellfish Thursday after high levels of paralytic shellfish poison (PSP) were found in oysters and clams harvested off Orcas Island.
In a news release, the state Department of Health said people should avoid eating shellfish harvested from Buck Bay on July 26 and 27, which were sold to consumers and restaurants via the Buck Bay Shellfish Farm. Officials said biotoxin monitoring detected PSP levels nearly four times the allowable level for harvesting.
Fortunately, no illnesses stemming from the recalled shellfish have been reported. The Buck Bay growing area is closed until further notice.

DOH said PSP is a naturally occurring marine biotoxin produced by certain algae that shellfish eat, and cooking or freezing does not destroy it. Symptoms appear quickly, and severe reactions can be fatal.
Symptoms include:
