Summary

Foodborne filamentous fungi produce mycotoxins, posing health risks like cancer and immunosuppression. Key mycotoxins include aflatoxins, ochratoxin A, fumonisins, trichothecenes, and zearalenone, impacting global health.

Area of Science:

  • Food safety and toxicology
  • Mycology
  • Public health

Background:

  • Filamentous fungi in food can produce mycotoxins, leading to adverse human health effects.
  • Mycotoxins are a significant global health concern, ranging from allergic reactions to cancer.

Purpose of the Study:

  • To identify key mycotoxins impacting human health globally.
  • To outline the fungal sources and food commodities associated with these mycotoxins.

Main Methods:

  • Expert identification of globally significant mycotoxins.
  • Review of fungal species and food types producing these toxins.

Main Results:

  • Five mycotoxins are critical: aflatoxins (carcinogenic, in peanuts/maize), ochratoxin A (kidney toxin, in cereals/grapes/coffee), fumonisins (oesophageal cancer, in maize), trichothecenes (immunosuppressive), and zearalenone (oestrogenic).

  • Specific fungal species like Aspergillus and Fusarium are linked to particular mycotoxins and food sources.
  • Current data may underreport mycotoxin-related mortality.

    • Conclusions:

    • Understanding mycotoxin sources and effects is crucial for public health.
    • Targeted surveillance and control measures for specific mycotoxins in susceptible foods are needed.
    • Further research is required to accurately assess the full impact of mycotoxins on human mortality.
