Aflatoxins (AF) are a group of fungal toxins that
contaminate foods and feeds with adverse health impact on human beings and
animals. A total of sixty three (63) samples of Groundnut kernels from three
(3) Agricultural zones of Sokoto State, were analysed for the presence of
Aflatoxins B1 (AFB1), B2 (AFB2), G1 (AFG1) and
G2 (AFG2) using High Performance Liquid Chromatography (HPLC). The
Aflatoxin was detected in 82.5%, the total Aflatoxin concentration ranged
between 0.9-646.0 μg/kg. All four types of AF were detected from all samples,
out of the total samples analysed 38.10% contained AF levels above the Nigerian
(20 μg/kg) limits for AF, while 66.7% samples had AF concentrations above the
European Union maximum tolerance level of 2μg/kg for AFB1 and Total
Aflatoxin(Tot AF) of 4μg/kg. The result shows that, there were significant (P
> 0.05) differences between the samples analysed in the state, as regards to
AFB1. The results also revealed that Groundnut kernel in the study
area have high frequency of contamination (82.5%).
awareness on danger of Aflatoxin contamination by all stakeholders is the key
in effective management of the problem.
Relevant quality control units must be reactivated to
assess the quality of the Groundnut kernels from which other products are made


Key words: Aflatoxin,
Contamination, Store Groundnut kernel and Agricultural zones.
