The Harmful Algal Bloom Network released preliminary results on Sept. 12 from their toxin testing of Kachemak Bay shellfish. Blue mussels gathered from Homer Harbor on Aug. 28 tested below the regulatory limit for paralytic shellfish toxins at less than or equal to 34 micrograms per 100 grams, or 34μg/100g. However, blue mussels collected from Homer Harbor on Sept. 4 tested at over double the regulatory limit of 80μg/100g, at 179μg/100g. Blue mussels from Gull Island were also over the limit, testing at 89μg/100g. Test results for levels of domoic acid, which causes amnesic shellfish poisoning, are still awaiting release.
The test results came after the State of Alaska Department of Health and Alaska Division of Public Health issued a PSP alert for Kachemak Bay on Sept. 9.
All harvesting of wild shellfish in the state of Alaska is considered “harvest at your own risk” and is not monitored by a regulatory agency. The HAB network only responds to potentially harmful bloom events occurring across the state and does not provide regulatory testing or oversight for wild shellfish harvesting or consumption.
Symptoms of paralytic shellfish poisoning include tingling in the lips and fingertips, numbing of the arms and legs, nausea, difficulty breathing, and even death. It is advised to get medical help immediately or call 911 if you experience nausea, vomiting, diarrhea, abdominal pain, tingling or burning lips, gums, tongue, face, neck, arms, legs, and toes, shortness of breath, dry mouth, a choking feeling, confused or slurred speech, and lack of coordination.
To report paralytic shellfish poisoning cases, contact the Alaska Department of Health and Social Services, Section of Epidemiology at 907-269-8000, or 800-478-0084 after hours.
