title: Occurrence of aflatoxins B1, B2, G1, and G2 in peanuts and their products marketed in the region of Campinas, Brazil in 1995 and 1996.
abstract: Samples of peanuts and their products marketed in the region of Campinas, Brazil in 1995 and 1996 were analysed in terms of aflatoxin B1, B2, G1, and G2 by thin-layer chromatography, aiming at the protection of consumer health. Of the 80 samples analysed, 35 of peanuts and 45 of peanut products, 41 (51%) presented contamination with aflatoxin, 11 of them being peanuts (27%) and 30 being products (67%), in a range of 43 to 1099 micrograms/kg for B1 + B2 + G1 + G2 with a 90th percentile of 415 (B1 + G1) and of 615 (B1 + B2 + G1 + G2). The results also demonstrated that aflatoxin B1 (AFB1) reached the highest incidence and the highest upper limits compared with all the other aflatoxins.
