Reviewing Evidence for Disturbance to Coral Reefs Increasing the Risk of Ciguatera [PDF]

Toxins
The hypothesis that disturbance to coral reefs creates new surfaces that increase the risk of ciguatera is premised upon the increased algal substrates that develop on these surfaces being colonised by high ciguatoxin (CTX)-producing Gambierdiscus ...

Origin of Ciguateric Fish: Quantitative Modelling of the Flow of Ciguatoxin through a Marine Food Chain [PDF]

Toxins, 2022
To begin to understand the impact of food chain dynamics on ciguatera risk, we used published data to model the transfer of ciguatoxins across four trophic levels of a marine food chain in Platypus Bay, Australia.

Reductive Amination for LC–MS Signal Enhancement and Confirmation of the Presence of Caribbean Ciguatoxin-1 in Fish

Toxins, 2022
Ciguatera poisoning is a global health concern caused by the consumption of seafood containing ciguatoxins (CTXs). Detection of CTXs poses significant analytical challenges due to their low abundance even in highly toxic fish, the diverse and in-part ...

Giant Moray Eel (Gymnothorax javanicus), a Long-Living Apex Predator That Poses a Food Safety Risk in the Pacific [PDF]

Marine Drugs
The giant moray eel (GME; Gymnothorax javanicus) is an important marine species that plays a key ecological role in reef systems and is a valued food source for indigenous communities.

Update on Methodologies Available for Ciguatoxin Determination: Perspectives to Confront the Onset of Ciguatera Fish Poisoning in Europe

Marine Drugs, 2010
Ciguatera fish poisoning (CFP) occurs mainly when humans ingest finfish contaminated with ciguatoxins (CTXs). The complexity and variability of such toxins have made it difficult to develop reliable methods to routinely monitor CFP with specificity and ...

Faster ciguatoxin extraction methods for toxicity screening [PDF]

Scientific Reports
Ciguatera poisoning (CP) is a severe global public health problem caused by the consumption of seafood products contaminated with ciguatoxins (CTXs). The growing demand for seafood products requires high-throughput testing for CTX-susceptible seafood ...

Toxicity Screening of a Gambierdiscus australes Strain from the Western Mediterranean Sea and Identification of a Novel Maitotoxin Analogue

Marine Drugs, 2021
Dinoflagellate species of the genera Gambierdiscus and Fukuyoa are known to produce ciguatera poisoning-associated toxic compounds, such as ciguatoxins, or other toxins, such as maitotoxins.

Ciguatoxin-Producing Dinoflagellate Gambierdiscus in the Beibu Gulf: First Report of Toxic Gambierdiscus in Chinese Waters

Toxins, 2021
Ciguatera poisoning is mainly caused by the consumption of reef fish that have accumulated ciguatoxins (CTXs) produced by the benthic dinoflagellates Gambierdiscus and Fukuyoa.

Characterisation of ciguatoxins

EFSA Supporting Publications, 2021
The primary objective of this specific grant was to characterize the risk associated to Ciguatera Poisoning (CP) in the EU by developing a sensitive methodology of LC-MS/MS. The preparation of reference materials including the main ciguatoxins (CTXs) responsible for the contamination was considered the secondary objective to facilitate the ...

Critical Review and Conceptual and Quantitative Models for the Transfer and Depuration of Ciguatoxins in Fishes

Toxins, 2021
We review and develop conceptual models for the bio-transfer of ciguatoxins in food chains for Platypus Bay and the Great Barrier Reef on the east coast of Australia.
