A new study forecasts an increase in ciguatera, the most common algae-induced seafood poisoning, along the Gulf of Mexico and the U.S.’s southeastern Atlantic coast.
Conducted by scientists from NOAA, North Carolina State University and Ocean Tester LLC, the new study blames rising global ocean temperatures caused by climate change for the spread of ciguatera. Gambierdiscus, microscopic ciguatera-causing algae, are abundant in the tropics, but ocean warming would enable some to move northward, and warmer temperatures could also mean larger and longer blooms of the harmful algae. Seaweed and marine animals, such as coral, first become toxic, then the species that feed on them. Ciguatera-causing toxins move up the food chain.
People are affected by contaminated reef fish, such as grouper, snapper and barracuda. “Contaminated fish have no specific taste,…
