Aflatoxin belongs to a group of fungal toxins known as mycotoxins, and is widespread in agricultural products and food. Aflatoxin is associated with both acute and chronic toxicity in animals and humans includingacute liver damage, liver cirrhosis, and liver cancers. Chronic toxicity associated with ingestion of low dose aflatoxin The aflatoxin LD50 rate (the dosage level that causes 50% of a group to die) for animals is between 0.5 and 10 mg/kg of the animal's weight. Aflatoxicosis - Aflatoxin Poisoning The technical term for poisoning by aflatoxin mycotoxins is aflatoxicosis. This usually occurs from eating food contaminated with aflatoxin mycotoxins.
Aug 25, 2017 · Structure. Aflatoxin B1, B2, G1 and G2 are compounds that yield native fluorescence. However, the fluorescence intensity of B1 and G1 is much less in comparison to that of B2 and G2 and accordingly, the sensitivity of B1 and G1 must be improved by changing from the natural form into a hydroxidized form using TFA derivatization. aflatoxin B 1 that is metabolized by enzymes found primarily in the liver.
