Ciguatera fish poisoning is the world’s most frequently reported seafood-borne illness.

It poses a serious health risk to tropical coastal communities, with some of the highest rates reported in Vanuatu. But now, Indigenous knowledge provides crucial insights for predicting fish poisoning outbreaks.

Our study documents a collaboration between scientists and Indigenous knowledge holders on Vanuatu’s Ambae island. It offers a powerful new model designed to protect people’s health in vulnerable regions.

Ciguatera poisoning occurs when people eat fish contaminated with ciguatoxins produced by marine algae that accumulate in reef-feeding fish. Symptoms can range from nausea and muscle pain to severe neurological effects. In some cases, the poisoning can lead to serious illness or even death.
