Risk Assessment of Pectenotoxins in New Zealand Bivalve Molluscan Shellfish, 2009–2019

Toxins, 2020
Pectenotoxins (PTXs) are produced by Dinophysis spp., along with okadaic acid, dinophysistoxin 1, and dinophysistoxin 2. The okadaic acid group toxins cause diarrhetic shellfish poisoning (DSP), so are therefore regulated.

Validation Study for Analytical Method of Diarrhetic Shellfish Poisons in 9 Kinds of Shellfish

Food Hygiene and Safety Science (Shokuhin Eiseigaku Zasshi), 2016
A method was developed for the simultaneous determination of okadaic acid, dinophysistoxin-1 and dinophysistoxin-2 in shellfish using ultra performance liquid chromatography with tandem mass spectrometry. Shellfish poisons in spiked samples were extracted with methanol and 90% methanol, and were hydrolyzed with 2.5 mol/L sodium hydroxide solution ...

A Snapshot on the Distribution of Coastal Phytoplankton Communities in Five HAB-Affected Bays in Eastern Visayas, Philippines

Frontiers in Marine Science, 2022
In recent years, harmful algal blooms (HABs), commonly known as red tide, have started to occur year-round in the warm tropical marine waters of Eastern Visayas, Philippines.

Effects of the Marine Biotoxins Okadaic Acid and Dinophysistoxins on Fish

Journal of Marine Science and Engineering, 2021
Natural high proliferations of toxin-producing microorganisms in marine and freshwater environments result in dreadful consequences at the socioeconomically and environmental level due to water and seafood contamination.

Okadaic acid as the causative toxin of diarrhetic shellfish poisoning in Europe.

Agricultural and Biological Chemistry, 1986
The toxic principle in mussels collected in France, Sweden, the Netherlands, and Spain that caused diarrhetic shellfish poisoning was identified to be okadaic acid by its chromatographic properties and spectral data.

Microbial communities and functional diversity in seafood

JSFA reports, EarlyView.
Abstract Functional diversity encompasses ecosystem processes that enhance adaptability to environmental change. This study explores the diversity of microorganisms associated with seafood. In this paper, we present our knowledge of microbial diversity in relation to seafood.

Using Machine Learning to Predict Phytoplankton Blooms in the Salish Sea

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Strong phytoplankton blooms occur every spring in the Salish Sea, but vary significantly, spatially and temporally. Natural variability and climate change make the prediction of the bloom challenging, as they affect both atmospheric drivers and nutrient interactions that contribute to the growth of phytoplankton. Understanding these drivers is

Risk Ranking of Microbiological Hazards in Food (2015–2019)

Food Risk Assess Europe, Volume 4, Issue 3, July 2026.
Abstract Microbiological food safety risks arise from pathogens that can contaminate food at different points along the food chain. Exposure to these hazards can result in illnesses that can vary widely in severity and duration, depending on factors such as the specific pathogen involved, the amount of the pathogen ingested, and the susceptibility of ...

Lipophilic Toxins in Chile: History, Producers and Impacts

Marine Drugs, 2022
A variety of microalgal species produce lipophilic toxins (LT) that are accumulated by filter-feeding bivalves. Their negative impacts on human health and shellfish exploitation are determined by toxic potential of the local strains and toxin ...

Detection of Diarrhetic Shellfish Poisons by LC-MS/MS

Journal of the Korean Society of Food Science and Nutrition, 2007
Diarrhetic shellfish poisons (DSP) such as okadaic acid (OA), dinophysistoxin-1 (DTX1), pectenotoxin-1(PTX1), PTX2, PTX6 and yessotoxin (YTX) were determined simultaneously by LC-MS/MS and mouse bioassay in the shellfishes (oyster, mussel, Washington purple clam, ark shell, scallop and short necked clam) collected at Tongyeong, from March to September,
