Food Additives and Contaminants, 2005
This paper reports the results of investigations of shellfish toxin contamination of products obtained from Shanghai seafood markets. From May to October 2003, 66 samples were collected from several major seafood markets. Paralytic shellfish poisoning (PSP) and diarrhetic shellfish poisoning (DSP) toxins in shellfish samples were monitored primarily by

Distribution of diarrhetic shellfish poisoning toxins in consignments of blue mussel
Food Additives and Contaminants, 2004Data describing the distribution of diarrhetic shellfish poisoning toxins in 13 consignments of Danish-produced blue mussels are reported. The content of diarrhetic shellfish poisoning toxins was measured by a liquid chromatography coupled with tandem mass spectrometry detection method, and mean levels in the 13 consignments varied from 58 to 243 ...

‘Diarrhetic’ Type Shellfish Poisoning in Nigeria
Bulletin of Environmental Contamination and Toxicology, 2009The safety of shellfish found and consumed in Nigeria is doubtful because no investigations have been carried out on their toxicity. The occurrence and toxicity of toxins in the commonly consumed Nigerian shellfish from Lagos, Warri, Oron, and Port Harcourt (PH) were investigated. Albino Wistar mice treated with chloroform extract of hepatopancreas (HP)

New Targets in Diarrhetic Shellfish Poisoning Control
Journal of Natural Products, 2005The toxic profile of dinoflagellates varies even among identical species, raising an interesting question about the mechanism of toxin regulation and production. In consequence, it also poses a considerable problem in their control methods. In this paper, we report on the isolation and structural elucidation of several new ester derivatives of okadaic ...

Diarrhetic Shellfish Poisoning in Narragansett Bay
Estuaries, 1987A two-year survey for diarrhetic shellfish poisoning (DSP) was conducted in Narragansett Bay using the mouse assay method. The suspected causative organisms,Dinophysis spp., were monitored at the same time. Only one shellfish sample, in September 1984, yielded an unequivocal positive result at a time when the dinoflagellate population was dominated byD.

Diarrhetic shellfish poisoning (DSP) toxins in South Australian shellfish
Harmful Algae, 2006Abstract In December 2003 a bloom of the toxic dinoflagellate Dinophysis acuminata (Claparede and Lachmann, 1859) was detected during routine plankton monitoring at Smoky Bay, on the west coast of South Australia (SA). Samples of scallops, razorfish and oysters were collected and analysed by LC–MS/MS to compare diarrhetic shellfish poisoning (DSP ...

Enzymatic hydrolysis of esterified diarrhetic shellfish poisoning toxins and pectenotoxins
Analytical and Bioanalytical Chemistry, 2007Okadaic acid (OA) and dinophysistoxins-1 and -2 (DTX1, DTX2), the toxins responsible for incidents of diarrhetic shellfish poisoning (DSP), can occur as complex mixtures of ester derivatives in both plankton and shellfish. Alkaline hydrolysis is usually employed to release parent OA/DTX toxins, and analyses are conducted before and after hydrolysis to ...

Phytoplankton selection by mussels, and diarrhetic shellfish poisoning
Marine Biology, 1998To better understand the dynamics of diarrhetic shellfish poisoning (DSP) contamination a field study was carried out on the feeding behavior of Mytilus galloprovincialis (Lmk) during an important DSP outbreak. The study was focused on the relationships between phytoplankton in seawater and algal cells, or their remnants, in mussel stomachs. During the

Causative species of diarrhetic shellfish poisoning (DSP) in Norway
Marine Biology, 1990This study was performed at Vikane in the Sognefjord, Norway, from September 1987 to October 1988 on the blue musselMytilus edulis collected monthly at three different depths (3 to 6, 6 to 8 and 8 to 12 m). Cell numbers of three species ofDinophysis from mussel digestive glands and in seawater were counted for each specimen.

2013
Algal biotoxins were determined on a weekly basis through the summers of 2009 and 2010 on mussel (Mytilus edulis) samples taken from three sites in Killary Harbour, a fjord located on the west coast of Ireland. Chemical (LC-MS), immunoassay (ELISA) and enzymatic (Protein Phosphatase, PP2A) methods were used to analyse algal diarrhetic shellfish ...
