Welcome to Ciguatera Online !


Each year, hundreds of thousands individuals are affected by Ciguatera Fish Poisoning (CFP). For some, this poisoning related to the consumption of toxic fish or seafood, will only last for a few days, for others, it will last for years…


This food borne illness, which concerned until recently only tropical and inter-tropical coral regions of the Pacific, Caribbean and Indian Ocean, tends to spread worldwide. In many ways, it remains a scientific and medical enigma.


This website provides a wide range of information on CFP, but also latest news about research improvement, downloadable information documents, links concerning CFP and gives you the opportunity to share your experience and ask questions. You will also find a toxic fish and fishing areas interactive map, which you can consult and implement.

Ciguatera-online is also providing a new generation of epidemiological surveillance tool that healthcare professionals and private individuals could use to anonymously report one or multiple CFP events. 


Collected information will make it possible to monitor CFP phenomenon and to accumulate relevant knowledge for a better understanding of the biological mechanisms involved.


Thank you in advance for your contribution, and welcome to!

March 2015






From 2 to 13 March 2015,  the Louis Malardé Institute will organize an International Workshop on Ciguatera Fish Poisoning. On this occasion, ILM will host several international experts (IAEA, IOC-UNESCO, NOAA, ...) and participants from 10 countries of the Asia-Pacific region for the RAS7026 project led by the International Atomic Energy Agency (IAEA).

This workshop will include:

-general courses

- identification of microorganisms potentially hazardous to human health,

- learning of the different toxins detection techniques in fish,

-establishment of a monitoring network (Sampling techniques, epidemiological data collection, ...).

Trochus, a potential vector of CFP?

Tectus niloticus 01

In June 2014, 9 Dutch, French and Italian tourists have been poisoned following the consumption of trochus (Tectus niloticus, Linnaeus 1767), caught at Anaho bay in the island of Nuku-Hiva, Marquesas archipelago (French Polynesia).        carte nuku hiva engTR

With the cooperation of the Sentinel Network of French Polynesia’s Health Directorate (DS), the Marine Resources and Mining Directorate (DRMM) and Louis Malardé Institute (ILM), samples of trochus have been collected to run toxicology tests in an attempt to confirm the presence of ciguatoxins or toxins of other kinds. Preliminary analyses conducted by ILM’s Laboratory of Toxic Micro-algae have confirmed the presence of liposoluble toxins (ciguatoxins) and other water-soluble toxins (their identification is still underway).

Recently we acknowledge that poisoning due to marine invertebrates, such as urchins and clams, could cause a CFP like syndrome (see chapter on CSP). It was the first case ever officially reported by the monitoring network of french polynesie of a trochus related poisoning. Is trochus a new species at risk of ciguatera in this area? Ongoing analyses seem to confirm it. 

For your information, Trochus were introduced in French Polynesia in 1957 and it is prohibited to fish, possess, transport, market or consume them.

Enigm ciguatera

Launching of the ENIGMciguatera study

 In collaboration with the Hospital of French Polynesia, Louis Malardé institute has officially launched its study on chronic forms of ciguatera.

This 5-year project aims to assess the extent of CFP chronic sequelae, to precisely know how they occur, to determine the underlying biological mechanisms involved in it and to identify potential relief solutions.

This forward-looking approach will require collection of patients’ medical history, using a detailed anonymous questionnaire.

To find more information or participate in this study, please contact us.
