Some major mycotoxins and their mycotoxicoses--an overview

Area of Science:

• Agricultural Science
• Food Safety
• Toxicology

Background:

• Mycotoxins are toxic secondary metabolites produced by fungi, with historical evidence suggesting their presence for millennia.
• Initially considered a storage issue, mycotoxins are now known to form both during crop storage and in the field.
• Recognition of aflatoxins in the 1960s marked a turning point in understanding these fungal toxins.

Purpose of the Study:

• To provide an overview of mycotoxins, their historical context, and significance.
• To highlight key mycotoxins of concern, including aflatoxins, deoxynivalenol, fumonisins, zearalenone, T-2 toxin, ochratoxin, and ergot alkaloids.
• To discuss the varied diseases (mycotoxicoses) caused by mycotoxins and the diagnostic challenges.

Main Methods:

• Review of historical and scientific literature on mycotoxins.
• Identification of significant mycotoxins based on occurrence frequency and toxicity.
• Discussion of diagnostic approaches for mycotoxicoses.

Main Results:

• Mycotoxins have a long historical presence, with significant scientific recognition emerging in the mid-20th century.
• Key mycotoxins like aflatoxins, deoxynivalenol, and fumonisins pose risks due to their carcinogenicity and widespread occurrence.
• Mycotoxicoses present diverse clinical signs, often mimicking other diseases, complicating diagnosis.

Conclusions:

• Accurate diagnosis of mycotoxicoses relies heavily on robust testing for mycotoxins.
• Effective mycotoxin testing involves proper sampling, preparation, and analytical procedures.
• Understanding the prevalence and toxicity of mycotoxins is essential for public and animal health.
