Tetrodotoxin and paralytic shellfish toxins in Philippine crabs.

Agricultural and Biological Chemistry, 1986
The frequent occurrence of lethal specimens of Zosimus aeneus and Atergatis floridus on southern Negros Island, Philippines, was confirmed by mouse lethality tests. Among eight specimens of Z. aeneus analyzed by fluorometric liquid chromatography, tetrodotoxin and its derivatives were dominant in five indicating the possible involvement of tetrodotoxin

Comparative paralytic shellfish toxin accumulation in three important Aotearoa New Zealand marine invertebrate species: kina (Evechinus chloroticus), pāua (Haliotis iris) and hohehohe (Panopea zelandica)

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1252-1264, December 2025.
ABSTRACT This study investigated the potential for paralytic shellfish toxin (PST) accumulation in three of Aotearoa New Zealand's (NZ) taonga seafood species: kina (urchin; Evechinus chloroticus), pāua (abalone; Haliotis iris) and hohehohe (geoduck; Panopea zelandica) in laboratory exposures to the dinoflagellate Alexandrium pacificum.

Nutrient‐driven regulation of saxitoxin gene expression and toxin production in Raphidiopsis raciborskii (Cyanobacteria)

Journal of Phycology, Volume 61, Issue 6, Page 1738-1752, December 2025.
Abstract Raphidiopsis raciborskii is a diazotrophic cyanobacterium, globally distributed in aquatic environments and known for forming toxic blooms, thereby affecting ecosystem services. South American strains are producers of saxitoxins, potent neurotoxins harmful to humans and animals.

Marine Algal Toxins and Public Health: Insights from Shellfish and Fish, the Main Biological Vectors

Marine Drugs
Exposure to toxigenic harmful algal blooms (HABs) can result in widely recognized acute poisoning in humans. The five most commonly recognized HAB-related illnesses are diarrhetic shellfish poisoning (DSP), paralytic shellfish poisoning (PSP), amnesic ...

Liquid Chromatographic-Fluorometric Analysis of Paralytic Shellfish Toxins

Agricultural and Biological Chemistry, 1984
Alkaline oxidation of paralytic shellfish toxins with ten-butyl hydroperoxide yielded highly fluorescent derivatives. Even gonyautoxins I and IV and neosaxitoxin, which were nonfluorescing by previously proposed hydrogen peroxide oxidations, were successfully converted to fluorescent compounds.

Foodborne Hazards and Novel Technologies in Ready‐to‐Eat Crustaceans

Food Frontiers, Volume 6, Issue 6, Page 2647-2672, November 2025.
Biological hazards, including Listeria monocytogenes, norovirus, Salmonella, and Vibrio spp., and chemical hazards, including heavy metals, biotoxins, pesticides, pharmaceuticals, and personal care products, are of great concern regarding crustaceans and their consumption.

Removal of paralytic shellfish toxins by probiotic lactic acid bacteria. [PDF]

Toxins (Basel), 2014
Paralytic shellfish toxins (PSTs) are non-protein neurotoxins produced by saltwater dinoflagellates and freshwater cyanobacteria. The ability of Lactobacillus rhamnosus strains GG and LC-705 (in viable and non-viable forms) to remove PSTs (saxitoxin (STX), neosaxitoxin (neoSTX), gonyautoxins 2 and 3 (GTX2/3), C-toxins 1 and 2 (C1/2)) from neutral and ...

Oceanography and Pacific Oyster Biochemical Composition in a Novel Oyster‐Growing Region

Aquaculture, Fish and Fisheries, Volume 5, Issue 5, October 2025.
ABSTRACT The farming of Pacific oysters (Crassostrea [Magallana] gigas) is a rapidly growing industry in Alaska, where farms represent some of the highest latitude oyster cultivation efforts in the world. Little is known about the nearshore oceanography where Alaskan farms are located, or how the subarctic marine context influences oyster tissue ...

Paralytic shellfish poison algal biotoxins: Sardinia report 2002-2011 and non-compliance management

Italian Journal of Food Safety, 2013
Several microalgae of the genus Alexandrium (Alexandrium minutum and Alexandrium catenelle) can produce an algal biotoxin, the paralytic shellfish poison (PSP) that can be accumulated in the shellfish edible tissues making them hazardous to the consumer ...
