Aflatoxins (Aflatoxin B1,B2,G1,G2)
Aflatoxins are highly toxic for human and animal health. Long-term exposure to aflatoxin has been linked to increased incidence of liver cancer. Humans are exposed to aflatoxins by consuming foods contaminated with products of fungal growth. Aspergillus flavus and Aspergillus parasiticus are the moulds that produce aflatoxin. These fungi can produce their toxic compounds on almost any food that will support growth. Aflatoxin generally develops due to poor oil-seed storage conditions and presence of undesirable moisture in the oil seed.
