Aflatoxin vs. Mycotoxin: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on February 25, 2024
Aflatoxin is a specific type of mycotoxin produced by Aspergillus species; mycotoxins are a broader group of toxic compounds produced by fungi.

Key Differences

Aflatoxin is a specific mycotoxin produced primarily by Aspergillus species of fungi, known for its potency and carcinogenic properties. Mycotoxins, on the other hand, are a diverse group of fungal toxins affecting various food crops and products.
Aflatoxins are notorious for contaminating crops like peanuts and corn, posing serious health risks when ingested. Mycotoxins, including aflatoxins, can cause a range of health issues from acute poisoning to chronic diseases in humans and animals.
The chemical structure of aflatoxins makes them highly toxic and stable under various conditions. Mycotoxins, as a group, vary widely in their chemical structures and include a range of toxic compounds beyond aflatoxins.
Detection and regulation of aflatoxin levels are crucial for food safety, especially in warmer and humid regions. All mycotoxins, including aflatoxins, are subject to strict regulatory limits in food products to ensure safety.
Research on aflatoxin focuses on its occurrence, prevention, and mitigation in food crops. The study of mycotoxins encompasses a broader scope, investigating various fungi and their toxins across multiple environments.

Aflatoxin and Mycotoxin Definitions


A toxic compound affecting crops like corn and nuts.
Aflatoxin levels in stored grains must be carefully monitored.


A group of substances including aflatoxins, ochratoxins, etc.
Different mycotoxins pose varying health risks in foods.


A mycotoxin known for liver damage and cancer risks.
Aflatoxin exposure is closely linked to liver cancer.


Toxic compounds produced by various fungi.
Mycotoxin contamination in crops can lead to foodborne illnesses.


A potent carcinogenic mycotoxin from Aspergillus fungi.
Aflatoxin contamination in peanuts can pose serious health risks.


Chemicals causing diseases in humans and animals.
Mycotoxin exposure is a significant concern in animal feed.


A stable toxin resistant to heat and processing.
Aflatoxin remains a concern even in processed food products.


Regulated substances in the food industry.
Strict limits are set for mycotoxin levels in food products.


A regulated food contaminant due to its toxicity.
Food industries rigorously test for aflatoxin to ensure safety.


Fungal toxins with diverse chemical structures.
Mycotoxin research focuses on their identification and effects.


Any of a group of toxic compounds produced by certain molds, especially Aspergillus flavus, that contaminate stored food supplies such as animal feed and peanuts.


A toxin produced by a fungus.


(poison) Any of a family of mycotoxins, produced by molds of the Aspergillus genus, that can be toxic, carcinogenic, mutagenic or teratogenic; typically found as contaminants of animal food or peanuts.


(biochemistry) Any substance, produced by a mold or fungus, that is injurious to vertebrates upon ingestion, inhalation or skin contact.


A potent carcinogen from the fungus Aspergillus; can be produced and stored for use as a bioweapon


A toxin produced by a fungus
