Ciguatera Fish Poisoning (CFP) is the most frequently reported seafood-toxin illness in the world, and it causes substantial physical and functional impact. It produces a myriad of gastrointestinal, neurologic and/or cardiovascular symptoms which last days to weeks, or even months. Although there are reports of symptom amelioration with some interventions(More)
In June of 1996, three family members were diagnosed as suffering from neurotoxic shellfish poisoning (NSP) as a result of eating shellfish harvested from Sarasota Bay, Florida. Urine from two of these patients and extracts of shellfish collected from the same location were analyzed by radioimmunoassay (RIA) and by receptor binding assay. Activity(More)
In October of 1996, a Gymnodinium breve bloom occurred in shellfish harvesting waters of Alabama, Mississippi and Louisiana, Gulf of Mexico, USA. Bloom densities reached 5.6x10(5) cells liter(-1) and bloom residence at shellfish sampling stations ranged from 3 to 28 days. Brevetoxin-2 dominated G. breve toxin profiles in bloom seawater extracts. Shellfish(More)
Previously, we analyzed Eastern oysters (Crassostrea virginica) naturally exposed to a Karenia brevis red tide and found that brevetoxins (PbTx) are rapidly accumulated and metabolized. Several metabolites were isolated and later identified, including a cysteine-PbTx conjugate (MH(+): m/z 1018) and its sulfoxide product (m/z 1034). In the present study, we(More)
On 24 February 1995, six U.S. soldiers serving with the Multinational Force in Haiti became ill after eating a locally caught fish identified as the greater amberjack Seriola dumerili. The victims presented with nausea, vomiting, watery diarrhea and abdominal cramps 5-8 hr after consumption. Also present in some victims were numbness in the extremities or(More)
Ciguatera fish poisoning is a seafood-borne illness caused by consumption of fish that have accumulated lipid-soluble ciguatoxins. In the United States, ciguatera is responsible for the highest reported incidence of food-borne illness outbreaks attributed to finfish, and it is reported to hold this distinction globally. Ciguatoxins traverse the marine food(More)
et al. Social, political and economic factors responsible for the reemergence of trichinellosis in Serbia: a case study. An outbreak of trichinellosis due to consumption of bear meat infected with Trichinella nativa in 2 northern Saskatchewan communities. To the Editor: Ciguatera outbreaks usually occur in the area between 35° north and 35° south latitude ,(More)
The metabolism and elimination of brevetoxins were examined in the Eastern oyster (Crassostrea virginica) following controlled exposures to Karenia brevis cultures in the laboratory. After a 2-day exposure period ( approximately 62 million cells/oyster), elimination of brevetoxins and their metabolites was monitored by using liquid chromatography/mass(More)
Following the 2010 Deepwater Horizon oil spill, petroleum-related compounds and chemical dispersants were detected in the waters of the Gulf of Mexico. As a result, there was concern about the risk to human health through consumption of contaminated seafood in the region. Federal and Gulf Coast State agencies worked together on a sampling plan and(More)
