Aquatic Toxins Program

man at desk

The role of the Aquatic Toxins Program is to prevent and reduce illness. One of the important ways we do this is by providing accurate information to residents and visitors, local health departments, the medical community and other interested people. With this information, people can make informed and healthy choices about their recreational activities and seafood consumption.

The following documents have information on the types of illnesses people may experience if they come into contact with a harmful algal bloom or toxin.

Neurotoxic Shellfish Poisoning (NSP) is caused by the consumption of molluscan shellfish contaminated with brevetoxins, which are produced by a marine dinoflagellate called Karenia brevis. Symptoms can include abdominal pain, nausea, vomiting, diarrhea, progressive paresthesia, ataxia, myalgia, headache, vertigo, and sometimes paradoxical temperature sensation (reversal of hot and cold sensations, as seen in Ciguatera Fish Poisoning). Contaminated shellfish are not detectable by taste or odor. The toxin cannot be removed by cooking, freezing, or other storage or preparation methods.
