What is the Difference Between Aflatoxin and Mycotoxin?

🆚 Go to Comparative Table 🆚

Aflatoxin and mycotoxin are terms related to toxic compounds produced by certain molds. The key difference between aflatoxin and mycotoxin lies in their specific origin and toxicity:

  • Aflatoxin: Aflatoxins are a type of mycotoxin produced by certain Aspergillus molds, such as Aspergillus flavus and Aspergillus parasiticus. They are amongst the most poisonous mycotoxins and are commonly found in corn, sorghum, wheat, rice, soybean, peanut, sunflower, and cotton seeds. Aflatoxins are potent hepatotoxins and carcinogens in the liver.
  • Mycotoxin: Mycotoxins are secondary metabolites produced by a variety of mold species that are toxic compounds. They can cause a range of adverse health effects when consumed, posing a serious health threat. There are several hundred mycotoxins identified, with aflatoxins being one of the most severe due to their toxicity. Other notable mycotoxins include ochratoxin A, patulin, fumonisins, zearalenone, and nivalenol/deoxynivalenol.

In summary, aflatoxins are a specific, highly toxic type of mycotoxin produced by Aspergillus species, while mycotoxins are a broader category of toxic compounds produced by various mold species.

    Aflatoxin and mycotoxin are both fungal toxins that can cause adverse health effects in humans and animals. Here is a table summarizing the differences between aflatoxin and mycotoxin:

    Property Aflatoxin Mycotoxin
    Definition Aflatoxin is a specific type of mycotoxin produced by Aspergillus species. Mycotoxin is a secondary metabolite of a mold that is a toxic compound.
    Toxicity Aflatoxins are the most poisonous type of mycotoxins. Mycotoxins are toxic compounds synthetized by fungi, with varying levels of toxicity.
    Production Aflatoxins are produced only by Aspergillus species. Mycotoxins are produced by various types of fungi.
    Types There are four major aflatoxins: B1, B2, G1, and G2. There are hundreds of different mycotoxins.
    Physiochemical properties Aflatoxins are the smallest mycotoxin and essentially planar, facilitating their intestinal absorption and interaction with adsorbents. Mycotoxins have diverse physiochemical properties, including size, volume, and mobility.
    Health effects Aflatoxins are known to cause vomiting, necrosis, anorexia, fatty liver, liver cancer, and diarrhea. Mycotoxins can cause a variety of adverse health effects, including cancers and inhibition of protein synthesis.

    In summary, aflatoxin is a specific, highly toxic type of mycotoxin produced by Aspergillus species, while mycotoxins are a diverse group of toxic compounds produced by various fungi. Both aflatoxins and mycotoxins can cause adverse health effects in humans and animals.
