 Shellfish caught in Alaska can lead to paralytic shellfish poisoning (PSP).PSP is caused by toxins released by dinoflagellate, a type of algae, which are extremely poisonous (1000 times more potent than cyanide) and can lead to death by paralyzing the breathing muscles.Due to warming oceans algae blooms have become more widespread, thereby increasing the likelihood of intoxications of various types.
