A total of sixty three (63) samples of Groundnut oils comprising of twenty one (21) samples each from three (3) Agricultural zones of Sokoto, were collected and assessed for Aflatoxin B1, Aflatoxin B2, Aflatoxin G1and Aflatoxin G2, using High Performance Liquid Chromatography. The Aflatoxin was detected in 71.4% of the samples. Total Aflatoxin ranged 0.11-45 μg/kg, All the types of Aflatoxin were detected except AFG2 which was not detected from all the sample zones. Of the total samples assessed 4.8% contained levels above the Nigerian (20 μg/kg) limits, while 44.4% of the samples had Aflatoxin concentrations above the European Union tolerance level of 2μg/kg for AFB1 and 38.1% for Total Aflatoxin of 4μg/kg. The result shows that, there were significant (P < 0.05) differences between the samples analysed. The results also revealed that Groundnut oil from Isa zone have the highest frequency of contamination (76.2 %) which was statistically similar to that of Tambuwal (71.4%) but significantly different from Sokoto (66.7%). Aflatoxin levels in this study were found to be lower than the legal limit regulated in Nigeria. This indicated that majority of the Sokoto oils in this study area are safe.

Key Words: Aflatoxin, Contamination, HPLC, Groundnut Oil and Agricultural zones.
