Title : Assessment of contamination of sesame seeds (Sesamum Indicum) produced, processed and sold by total aflatoxin in the region of Ségou and the district of Bamako from 2018 to 2020

Abstract:

Introduction: Sesame (Sesamum indicum) is an annual plant of the Pedaliaceae family, erect 0.5 to 2 m tall, with a cycle of 80 to 180 days, widely cultivated for its grains. It brings a considerable income to producers and generates a very important resource per year. Despite its economic and food importance, meeting its sanitary quality and export criteria remain a challenge.

Objective: The objective of this study was to evaluate the contamination of sesame produced, processed and marketed by total aflatoxins in Ségou and in the District of Bamako

Methodology: The study was analytical with a descriptive aim. The search for mycotoxins (aflatoxins B1, B2 and G1, G2) by the NF EN ISO 16050 method October 2011; Reversed-phase HPLC with fluorescent detection and post-column bypass after extraction with solvent (methanol-water).

Results: The results of analyses by producers (OPs) and wholesalers in the communes of Bamako showed that the majority of the samples complied with the standards of the European Union (4μg/Kg) and that of the Codex Alimentarius (10μg/Kg). Except for Commune II. The average concentrations of Aflatoxins in the samples of processors from the localities of Bla, Ségou and San were below the two standards. Only the average concentrations of the Bamako samples were higher than the two standards. Future research must commit to assessing the risks associated with the consumption of sesame seeds.

Conclusion and perspectives: The study highlights contamination of sesame by total aflatoxin, especially among wholesalers in commune II. It is essential to strengthen conservation practices throughout the production chain. Future research will need to deepen the assessment of the health risks associated with consumption and propose corrective measures to improve the quality of sesame.
