Intake of aflatoxins through the consumption of peanut products in Brazil

To estimate daily intake of aflatoxins from peanut products consumed by the population of Paraná State (Brazil), 100 samples of peanut products were collected between July 2006 and April 2007. Aflatoxins were determined by an HPLC method with fluorescence detection. There was a 50% occurrence of aflatoxins (B1, B2, G1 and G2) in concentrations ranging from 0.5 to 113 ng g−1, with 13 samples with levels above 20 ng g−1. Intake was calculated for average and high adult consumers of peanut products and it was compared with provisional maximum tolerable daily intake (PMTDI). The estimated probable daily intake (PDI) for aflatoxin B1 (AFB1) varied from 0.6 to 10.4 ng kg−1 bw day−1, exceeding the PMTDI of 0.4 ng kg−1 bw day−1 for carriers of hepatitis B virus.
