Aflatoxins and disease

R C Patten

    The American Journal of Tropical Medicine and Hygiene
    |March 1, 1981
    PubMed
    Summary

    Aflatoxins, produced by Aspergillus flavus fungus, are suspected environmental factors contributing to cancer. This paper reviews historical and epidemiological evidence linking aflatoxin exposure to various diseases, highlighting its potential global impact on cancer incidence.

    Area of Science:

    • Environmental Health
    • Toxicology
    • Epidemiology

    Background:

    • Growing evidence suggests environmental factors are primary drivers of most cancers.
    • The epidemiological data for many suspected environmental carcinogens remain inconclusive.
    • Aflatoxins, mycotoxins produced by Aspergillus flavus, are ubiquitous and pose a significant public health concern due to their toxicity.

    Purpose of the Study:

    • To consolidate and review the existing historical and epidemiological evidence on the association between aflatoxin exposure and human diseases.
    • To assess the potential role of aflatoxins as a significant global cause of cancer.

    Main Methods:

    • Literature review of historical data.
    • Analysis of epidemiological studies investigating aflatoxin exposure and disease outcomes.
    • Synthesis of evidence on toxicity and human ingestion patterns.

    Main Results:

    • Aflatoxins are widely distributed environmental contaminants with known toxic properties.
    • Human ingestion of aflatoxins is frequent in many parts of the world.
    • Historical and epidemiological data suggest a plausible link between aflatoxin exposure and increased cancer risk.

    Conclusions:

    • Aflatoxins represent a significant, yet often underestimated, environmental risk factor for cancer globally.
    • Further research and public health interventions are warranted to mitigate aflatoxin exposure and its associated health risks.
