Title : Evaluation of the sanitary quality of sesame seeds (Sesamum Indicum) produced, processed and sold in the Ségou region and the district of Bamako from 2018 to 2020

Abstract:

Sesame, one of the oilseed crops grown in Africa, brings in considerable income for producers and generates a very substantial annual resource. Despite its economic and food importance, meeting its sanitary quality and export criteria remains a challenge. In order to find solutions to these concerns, the aim of this study was to assess the sanitary quality of sesame seeds produced, processed and sold in Ségou and the District of Bamako. The study was a descriptive analytical study of the sanitary quality of sesame. The main results obtained showed that 37% of sesame seeds from wholesalers, 10.87% of samples from processors of Small and medium-sized enterprises (MPE) and 6% of samples from farmers' organisations (OP) were significantly contaminated with thermo-tolerant coliforms, mainly salmonella. The highest aflatoxin content was found in the wholesaler samples (15.38 μg/Kg). Lead residue levels in the wholesaler samples were above the standard (0.3mg compared to the standard 0.2mg). The pesticides (Endosulfan A, Endosulfan B, Deltametrin, Dieldrine, Endrine, pp'DDT, Aldrine, Heptachlor, Malathion, Parathion, Op'DDT and Lindane) were all detected in the samples from OPs. In grossites, Deltametrin, Dieldrin, Endosulfan A, Endosulfan B, Endrin and pp'DDT were detected at levels exceeding standards. Future research needs to be undertaken to assess the risk associated with eating sesame seeds.
