Aflatoxins are produced mainly by Aspergillus flavus and Aspergillus parasiticus that grow in improperly stored cereals. Aflatoxin B₁ (AFB₁) is a potent hepatocarcinogen in a variety of experimental animals including human beings. In spite of a high attention to the hepatocarcinogenecity of AFB₁, the relative toxicity of aflatoxins (AFB₂ and AFG₁) is not fully clarified. Sprague-Dawley male rats were orally administered with AFB₁, AFB₂, and AFG₁ at the dose of 250 μg/kg (additionally including a dose of 1250 μg/kg for AFB₁) body weight.
