摘要：

This study investigated the occurrence of aflatoxin B-1 in peanuts and peanut products marketed in the State of Rio Grande do Sul, Brazil. One hundred one samples of peanuts and peanut products were collected and analyzed by thin-layer chromatography with a charge-coupled device system. Aflatoxin B1 was present in 14% of the samples analyzed, in concentrations ranging from 24.0 to 87.5 mu g/kg in the peanut samples and from 22.0 to 84.6 mu g/kg in the peanut-product samples. These values exceeded the Brazilian regulatory limit (20.0 mu g/Kg for aflatoxins B-1+G(1)+B-2+G(2)). These results suggest that although aflatoxin contamination in peanuts marketed in southern Brazil is lower than in other Brazilian regions, it is still a serious problem for human health and the economy.
