However, it is possible to avoid and/or reduce the severity of a poisoning by applying a few  rules:  

Seek advices from the local fishermen. They have, most of the time, a very good knowledge of the fishing areas and species to avoid

Consult the map of toxic species fishing zones available on the CIGUAWATCH platform.

Seek advice from the authority in charge of the ciguatera surveillance of the country in which you are located.

Avoid eating the head and viscera, where toxins are mostly concentrated.

As soon as the first symptoms appear, consult a doctor or contact the poison control center closest to you.

During the weeks following the poisoning, remove marine products, animal proteins (especially red meats), alcohol and nuts (walnuts, peanuts, etc.) from your diet. Their consumption is likely to temporarily revive itching, muscle pain, malaise, asthenia, etc. This "hypersensitivity" phenomenon will fade over time. You will gradually be able to reintroduce these foods and drinks into your diet.

In addition to the treatment prescribed by your physician, it is suggested to take a vitamin C, B1, B6 and B12 therapy until the symptoms resolve.

If you have not consulted a doctor, remember to declare your poisoning on the online reporting system or to This email address is being protected from spambots.

Ciguatoxins can contaminate breast milk, it is recommended to suspend breastfeeding for 4 weeks in case of poisoning.
