Ciguatera in Mexico (1984⁻2013)

Area of Science:

• Marine biology
• Toxicology
• Epidemiology

Background:

• Ciguatera fish poisoning has historical records in Mexico dating back to 1862.
• The review analyzes 464 cases from 25 events between 1984 and 2013.
• Ciguatera is the second most prevalent seafood poisoning in Mexico, after paralytic shellfish poisoning.

Purpose of the Study:

• To review the current status of ciguatera fish poisoning in Mexico.
• To identify the primary fish vectors involved in human intoxications.
• To explore the ecological and toxicological aspects of associated dinoflagellate species.

Main Methods:

• Literature review of historical records and epidemiological reports.
• Analysis of case data from 1984 to 2013, including geographical distribution.
• Identification of implicated fish species and associated dinoflagellate genera.

Main Results:

• Baja California Sur (51.72%) and Quintana Roo (35.12%) reported the highest number of ciguatera cases.
• Snapper, grouper, and great barracuda were identified as key fish vectors.
• Dinoflagellates such as Gambierdiscus, Ostreopsis, and Prorocentrum are linked to outbreaks.

Conclusions:

• Ciguatera fish poisoning represents a growing public health issue in Mexico, particularly in coastal regions.
• Understanding the fish vectors and causative microorganisms is crucial for risk assessment and management.
• Further research is needed to fully understand and mitigate the impact of ciguatera in Mexico.
