aflatoxins

[af′lātok′sins]
Etymology: Gk, a, not; L, flavus, yellow; Gk, toxikon, poison
a group of carcinogenic and toxic factors produced by Aspergillus flavus food molds. The mycotoxins cause liver necrosis and liver cancer in laboratory animals and are believed to be responsible for a high incidence of liver cancer among people in tropical regions of Africa and Asia who may consume moldy grains, peanuts, or other Aspergillus-contaminated foods.

aflatoxins

Poisonous fungal products produced by Aspergillus flavus which grows on peanuts and grains stored in damp conditions. Aflatoxins act by binding to enzymes so that cell metabolism is blocked. If the fungus is eaten by cattle, the toxins can be released in the milk. Afflatoxins are believed to be a cause of primary liver cancer in people, especially those who have had HEPATITIS B.
