Aflatoxin G2 is primarily known for its role as a mycotoxin produced by certain strains of Aspergillus fungi, particularly in contaminated agricultural products. It is a potent hepatotoxin and carcinogen, making its detection critical in food safety monitoring. It is commonly analyzed in quality control of commodities like peanuts, corn, and tree nuts to prevent human and animal exposure. Due to its high toxicity, it is also used in research settings to study liver damage, DNA adduct formation, and mechanisms of carcinogenesis. Sensitive analytical methods such as HPLC and mass spectrometry are employed to detect trace levels in food and biological samples. Its presence serves as a marker for fungal contamination and poor storage conditions in food supply chains.
