Analysis of Microbial Load in Local Variety Sesame Grown in Chad

This study was carried out to assess the health quality of sesame seeds, a local variety, grown in Chad with a view to contributing to their food and economic valorization. The seeds come from experimental fields in two distinct zones: Kournari in the Sahel and Kélo in the Sudanian zone. The health quality of sesame was assessed by microbiological analyses. The results showed low contamination of the samples analyzed by total coliforms, Escherichia coli and yeasts and molds. Analysis of the results showed a total absence of yeasts and molds in the samples from Kournari. Salmonella was absent in all samples analyzed. The health quality of these sesame products is therefore good and can be used for physicochemical analyses. But the contamination of part of the samples confirms the need for good hygiene and good agricultural production techniques. It is therefore necessary to ensure compliance with good agricultural practices and good post-harvest treatment practices for sesame.
