Because of unsafe levels of paralytic shellfish poison (PSP), public-health officials have initiated the temporary closure.
Public-health officials have temporarily closed Vashon-Maury Island’s Quartermaster Harbor to recreational shellfish harvesting because of unsafe levels of paralytic shellfish poison (PSP).
The closure, initiated by the state Department of Health, includes harvesting for clams, geoduck, scallops, mussels, oysters, snails and other invertebrates, according to a Public Health – Seattle & King County news release. Commercial harvesting is not affected.
The harbor has closed for the same reason in the past.
Symptoms, which usually occur within the first hour of digestion, begin with numbness. Patients may experience headaches, dizziness, nausea and loss of muscle coordination. In extreme cases, patients can suffer muscle paralysis and respiratory failure, potentially leading to death.
