Ciguatera fish poisoning in Miami

D N Lawrence, M B Enriquez, R M Lumish

    JAMA
    |July 18, 1980
    PubMed
    Summary

    Ciguatera fish poisoning is a significant foodborne illness in Miami, primarily linked to consuming grouper and snapper. This study highlights the need for better toxin detection methods to address the ongoing public health concern.

    Area of Science:

    • Environmental Health
    • Foodborne Illness Epidemiology
    • Toxicology

    Background:

    • Ciguatoxic fish pose a persistent foodborne disease risk in Miami.
    • Ciguatera fish poisoning is a significant public health issue requiring epidemiological study.

    Purpose of the Study:

    • To conduct an epidemiologic study of ciguatera fish poisoning in Miami.
    • To analyze reported cases from 1974-1976 to understand the syndrome's characteristics.

    Main Methods:

    • Reviewed 129 reported cases of ciguatera fish poisoning in Dade County (Miami) from 1974 to 1976.
    • Defined cases by gastrointestinal and neurological symptoms within 36 hours of fish consumption.

    Main Results:

    • Grouper and snapper were the most frequently implicated fish species.
    • No significant impact of storage or preparation methods on fish toxicity was observed.
    • A seasonal pattern with increased incidence in late spring and summer was noted.

    Conclusions:

    • The true incidence of ciguatera fish poisoning in Miami may be underestimated, potentially ten times the reported number.
    • An average annual incidence of at least five cases per 10,000 population is suggested.
    • Advances in ciguatoxin research are crucial for developing necessary toxin detection assays.
