title: [Measurement and levels of aflatoxins in small-scale pressed peanut oil prepared in the Diourbel and Kaolack regions of Senegal].
abstract: Aflatoxins are mycotoxins produced by some strains of fungus (Aspergillus) which develops in peanuts seeds. Peanuts oil and past are very used up in Senegal, then the aflatoxins poisoning risk are very actual. This study relates to the determination of contamination levels by aflatoxins from peanut oil food prepared by small scale production in areas of Kaolack and Diourbel. High Performance Liquid Chromatography (HPLC) analysis of the different samples showed that 80% of them were contaminated in the areas of Kaolack and Diourbel. Aflatoxin B1, B2, G1 and G2 has been detected with a profile of contamination almost identical in the both areas. Aflatoxin B1 was prevalent and has been found in over 85% of samples. Mean contents of this mycotoxin (the most dangerous toxin) is about 40 ppb, value widely superior to allowable specifications.
