Abstract

The grains of H. Vulgare commonly used for the elaboration of meals for humans and animals, could be contaminated with propagules of native fungi resulted from the intensive agricultural system of production. In addition, the unsuitable storage conditions could strongly influence the growing of undesirable fungi which could potential synthetiz emyco toxins. The aim of the present research work was the isolation of Aspergillus potential to synthetize ochratoxin A from the commercially available in H. vulgare. To this purpose, the grains were collected from various local stores, from grain of H. vulgare. Aspergillus were isolated in potato dextrose and in a Sabourauddextroseagar to determine the density and diversity. The potential for the synthesis of ochratoxin A by Aspergillus strains was then evaluated. The results were statistically evaluated using the software Anova/Turkey.Results indicate the presence of a relatively high number of propagules of Aspergillus spp which are contaminating the H. vulgare. Furthermore, 67% of the fungi present in H. vulgare have the potential to synthetize ochratoxin A. These results demonstrate the risk of consumption of those grains by humans.
