It states that Duwamish, a once-vibrant river, has been included on the list of the most polluted rivers across the state. It adds that the river was already pumped with metals and carcinogens from the heavy industry and consists fishes that are too toxic for human consumption.

The article focuses on rockfish on the coast of British Columbia (B.C.). Rockfish is known as the scorpion fish family, consisting over three hundred sub species. It is inferred that rockfish along the B.C. coast have low levels of toxins. It offers tips for handling rockfish, suggesting to hold them using a thumb and forefinger and grasping them over the lower lip. Information about the taste of rockfish and conservation efforts are provided.

The article looks at the case of Ronnie Martin, a television sitcom creator who developed an unknown lower abdominal illness after eating a raw fish seviche in Bora-Bora, French Polynesia. Martin contacted the author, a tropical medicine specialist, who came to the conclusion that Martin's illness was caused by toxin. Various toxins and worms within fish are discussed. The author believes Martin had the ciguatera fish toxin, caused by the microalga Gambierdiscus toxicus, ingested by the fish.

Ciguatera fish poisoning is caused by eating reef fish contaminated by algae-produced toxins -- even when fish look normal and have been handled and cooked appropriately. Symptoms include neurologic and gastrointestinal abnormalities and can persist for months. [ABSTRACT FROM AUTHOR]

The article discusses the issue about ciguatera fish poisoning in Texas. It states that ciguatera fish poisoning is becoming the most commonly reported disease caused by a marine toxin. According to The Journal of the American Medical Association, ciguatera fish poisoning is caused by eating fish containing toxins produced by the dinoflagellate Gambierdiscus toxicus. Its common symptoms include nausea, vomiting, and diarrhea.

The article presents a study conducted by Takeshi Yasumoto and colleagues which investigates the effectiveness of a test in preventing food poisoning associated with fish consumption. The findings of the study reveal that this test was proven effective in identifying 16 different forms of toxins present in fish from the Pacific Ocean. About 12 types of toxins in marine algae in French Polynesia were also revealed.

Ciguatera Foodborne Poisoning may be associated with rare reports of painful sexual intercourse after the consumption of the fish.

The article focuses on the study of Gambierdiscus launched by several scientists and funded by the Woods Hole Oceanographic Institution (WHOI) Ocean Life Institute's Tropical Research Initiative. The Gambierdiscus, accordingly, is a single-celled marine algae that lives on seaweeds and produces a substance that is transformed into a toxin when reef fish graze on seaweed and consume it. Its result, further, is ciguatera fish poisoning to people. To test the cell, WHOI Senior Scientist Don Anderson, University of Texas marine biologist Deana Erdner, and U.S. Food and Drug Administration chemist Robert Dickey, decided to map distributions of the cell to discover how strains and degrees of toxicity vary in different environments.
