Evaluation of mycotoxins and heavy metals pollution in some types of noodles in local markets

Abstract

This study was conducted to estimation mycotoxins and some heavy metals in some types of noodles in Salah Al-din governorate markets. In this study 6 species of Aspergillus were detected which were A. flavus, A. parasiticus, A. fumigatus, A. terreus, A. ochraceus and A. niger and 5 genus of fungi were Fusarium verticillioides, Penicillium, Mucor, Alternaria and Rhizopus isolated on the three types of media used. The results show presence of the three types of mycotoxins in all samples. The concentrations of the aflatoxin B1 ranged between 1.145 - 5.041 ppm. Concentrations of fumonisin between 8.498 - 19.496 ppm. Concentrations of ochratoxin A ranged between 3.960 - 52.543 ppm. The results also show that the concentration of copper and cadmium was at (0.50 - 1.23) (0.05 - 0.31) ppm respectively, while the concentration of lead was less than 0.1 ppm in all samples.
