Alaska has among the nation’s highest rates of paralytic shellfish poisoning, but reported incidents are declining.
Over the last decade, Alaska has reported fewer cases of a serious condition caused by consuming contaminated shellfish than in previous years.
The condition, also known as PSP, is a foodborne illness caused by neurotoxins known as saxitoxins, which are produced by harmful algal blooms that shellfish sometimes take into their systems while filter feeding, Newell explained. Anyone who experiences symptoms of the condition after consuming shellfish — which include tingling of the lips, tongue, fingers or toes; difficulty swallowing; dizziness; impaired coordination and muscle weakness — is encouraged to contact their medical provider immediately even if their symptoms appear mild, Newell said.
“This is likely due to a combination of factors including a large coastline, abundant shellfish populations, and environmental conditions conducive to formation,” the report said.
