UH finds staph-fighting ocean organism Mar 22, 2006
The big problem with marine toxins is that the organism that presumably causes the illness is a "natural inhabitant of the marine environment" rather than a product of sewage, Laws said. "The big issue is, Why do organisms occasionally produce large amounts of neurotoxin that find their way up the food chain and get into fish, specifically herbivorous reef fish people eat?".

Structures Of Marine Toxins Provide Insight Into Their Effectiveness As Cancer Drugs Sep 30, 2005
Adds Allingham: "These marine toxins can knock out the lynchpins in these long chains or cap their ends and kill cancer cells. Moreover, initial work shows that even a low dose of these toxins can bring a significant response.". Prior to the study published in PNAS, it was known that the marine toxins affect several forms of cancer - but not how they worked, says Rayment. (Science Daily)
Prenatal Exposure To Marine Toxin Causes Lasting Damage Sep 9, 2005
"The consequences are life-long. "The findings suggest we may need to re-evaluate monitoring of waters, shellfish and fish to make sure that the most sensitive parts of the human population are protected from toxic exposure to domoic acid," he continued. The researchers reported their findings in a forthcoming special issue dedicated to research on marine toxins of Neurotoxicology and Teratology. In 1987, more than 100 people in Canada became ill after eating cultured mussels contaminated with... (Science Daily)

Red tide is responsible for the production of marine toxins that cause Paralytic Shellfish Poisoning, a neurotoxin that accumulates in filter-feeding shellfish and can pose a serious threat to the public, according to information provided by NOAA.. Testing by the Commonwealth of Massachusetts and Woods Hole Oceanographic Institution show that the organism capable of producing the toxin is increasing and that the "bloom" is moving in an easterly direction toward Georges Bank.

Eating Seafood That Contains Toxic Substances Can Affect The Nervous System Apr 10, 2005
Geoffrey Isbister (Charles Darwin University, Darwin, Australia) and colleagues reviewed data on the neurological syndromes associated with the ingestion of common marine toxins. Their article details the three major clinical syndromes that present after the consumption of seafood containing toxic substances: ciguatera, puffer fish (tetrodotoxin) poisoning, and shellfish poisoning.

Study Methods, Strains Of Pfiesteria Are Both Critical In Determining Organism's Toxicity, Researchers Show Feb 25, 2005
Thats the main result of a wide-ranging study by Dr. JoAnn M. Burkholder, professor and director of the Center for Applied Aquatic Ecology at North Carolina State University, along with a dozen colleagues from several universities and research institutions, and a federal laboratory specializing in marine toxins. The research is published online in Proceedings of the National Academy of Sciences. (Science Daily)

Kerry Kicks Off Earth Day Commemoration by Outlining Planfor Healthy Oceans Apr 20, 2004
Various marine toxins afflict more than 90,000 people per year and account for 62 percent of all seafood-related illnesses. A 1999 report of the National Research Council warned that environmental threats such as these, as well as physical oceanographic processes that result in phenomena like El Nino and tsunamis, may have significant implications for the health of human populations.

NOAA MARINE BIOTOXINS PROGRAM Oct 30, 2003
Oct. 30, 2003 Harmful algal blooms have been recognized for producing toxins since earliest recorded time " and the waters that were in the river were turned to blood. And the fish that were in the river died; and the river stank and the Egyptians could not drink the water of the river..." However, confirmation of marine biotoxins has historically been elusive due to non-specific symptoms, the complexity of toxin detection and undefined levels of impact to affected species. Harmful Effects... (NOAA Magazine, DC)
