What foods contain aflatoxins?
Aflatoxins can occur in foods such as groundnuts, tree nuts, maize, rice, figs and other dried foods, spices, crude vegetable oils and cocoa beans, as a result of fungal contamination before and after harvest. Several types of aflatoxins are produced naturally.
How do you prevent aflatoxin?
Post-Harvest Drying & Storage Before storage, crops should be properly dried to prevent the development of aflatoxins. Sorting and disposing of visibly moldy or damaged kernels before storage has proven to be an effective method for reducing, but not eliminating, the development of aflatoxins (Fandohan, Zoumenou et al.
Which aflatoxin is most toxic?
Aflatoxin B1 is considered the most toxic and is produced by both Aspergillus flavus and Aspergillus parasiticus. Aflatoxin M1 is present in the fermentation broth of Aspergillus parasiticus, but it and aflatoxin M2 are also produced when an infected liver metabolizes aflatoxin B1 and B2.
Does popcorn have aflatoxin?
Popcorn can be contaminated with fungi mainly Aspergillus flavus and A. parasiticus,5 which produce toxic secondary metabolites called aflatoxins (AFs), that pass to the corn cob and grains in the field or during storage, although there are few reports about the risk of AFs in regard to popcorn consumption.
Do all nuts have aflatoxins?

What happens if you eat aflatoxins?
Large doses of aflatoxins lead to acute poisoning (aflatoxicosis) that can be life threatening, usually through damage to the liver. Outbreaks of acute liver failure (jaundice, lethargy, nausea, death), identified as aflatoxicosis, have been observed in human populations since the 1960s.
How do you detect aflatoxin?
Several methods including thin-layer chromatography (TLC), high-performance liquid chromatography (HPLC), mass spectroscopy, enzyme-linked immune-sorbent assay (ELISA), and electrochemical immunosensor, among others, have been described for detecting and quantifying aflatoxins in foods.
Does all peanut butter have aflatoxin?
For products such as peanut butter, the FDA conducts random checks and removes products from sale that fail food safety standards. Aflatoxin does not form in peanut butter once it is packed in containers, so if the production process is safe then the final product will be too when it reaches the consumer.
Do all nuts have aflatoxin?
Who discovered aflatoxin?
The discovery of aflatoxins began immediately after an outbreak of a disease of turkeys of unknown etiology in England in 1960. The disease was called Turkey “X” disease and was eventually attributed to a toxic groundnut meal imported from Brazil.
