STC PSP DATA

Currently STC collects blue mussels from Nahku Bay and test for paralytic shellfish toxins (PSTs) to ensure Tribal and local citizens are consuming shellfish safely. Furthermore we collect water samples to detect algae blooms as a pre-warning system. We generally collect samples on a biweekly basis unless the results are over the FDA threshold, then we collect weekly until the level returns to below FDA threshold.

Although we are currently only testing blue mussels, consumption of all shellfish should be approached with caution. This includes crabs and shrimp if consuming the innards.

It is also important to monitor dogs on the beach during blooms and high PST events, they can become ill from consuming molluscan shellfish, crabs, and other whole organisms that may have the toxins in their guts.

SYMPTOMS (If you consumed shellfish and have any of the following symptoms please seek help)

Shellfish affected by the poison don’t look, smell or taste any different than healthy ones. But once ingested, it can be deadly. Symptoms include tingling in the lips, mouth and extremities and can progress to dizziness and shortness of breath. According to the state, death can occur in as little as two hours in severe cases. Cooking or freezing shellfish does not get rid of PSTs.
