Ciguatoxin poisoning
Abstract
Introduction: Ciguatoxin poisoning, known as ciguatera, is the most common non-bacterial food poisoning associated with fish consumption. This type of poisoning is caused by ciguatoxins found in contaminated fish, which are considered to be potent marine biotoxins produced by dinoflagellates such as Gambierdiscus and Fukuyoa spp.
Objective: To present the current status of ciguatoxin poisoning, as a way to contribute to its diagnosis and adequate treatment.
Method: A bibliographic search was carried out in Pubmed, SciELO, Lilacs, SCOPUS and Cochrane databases. Ninety-seven articles were downloaded; they were incorporated into Zotero bibliographic manager and classified according to the aspects dealt with in the content. Duplicate articles were discarded, reducing the total number to 25, which are cited and referenced in the document.
Development: The prevalence of ciguatera is significantly underestimated due to the lack of identification of its symptoms; its diagnosis is clinical due to the lack of specific laboratory tests and is based on a history of ingestion of the fish and the presence of symptoms related to alterations in the functioning of peripheral nerves.
Conclusions: Ciguatera represents a multifactorial challenge, linked to marine ecosystems, public health and climate change. There is an urgent need to strengthen epidemiological surveillance, improve access to diagnostic methods and explore specific therapies. Interdisciplinary collaboration (toxicology, ecology, medicine), is key to mitigate its impact in a scenario of geographic expansion.
