Aflatoxins and aflatoxigenic fungi in export standard white and red sesame seeds (Sesamum indicum L.) from Ethiopia

The oil seed sectors one of the fastest growing in Ethiopia, both terms its foreign exchange earnings and as a source income for millions Ethiopians. Oilseed crops are recognized to be potentially suitable substrate production aflatoxins by aflatoxigenic fungi. This study intended evaluate knowledge, attitude practice sesame exporters about contamination, characterize determine level aflatoxins, from export standard white red Humera Wollega seeds. Twenty seven ready samples were collected Ethiopian Commodity Exchange (ECX) warehouse. Thousand weight, moisture, crude fat peroxide value determined according AOAC. Aflatoxin B1, B2, G1, G2 total at ng/g SupelTM Tox Aflazea cartridge clean up reversed-phase liquid chromatography. weight range 2.89-3.22 g/1000 seeds, moisture is 3.33-4.99%, 46.75-57.75% 2-8.2 meq/Kg. detected 1.32 - 2.12 ng/g, 1.52-31.98 16.2-48.28 0.56-9.04 0.44-64.96 respectively. contamination seeds could ruin oilseed thus decrease revenues state.
