Estimation of Some Mycotoxins and Heavy Metals in the Livers of Local and Imported Chickens Available in the Local Markets

Abstract

The current study aimed to estimate the concentrations of each of the metallic elements lead (Pb), copper (Cu), zinc (Zn) and cadmium (Cd) using the atomic absorption spectrometer (AAS) technique, and the residues of some mycotoxins using the High-performance liquid chromatography (HPLC) In samples of fresh, local and frozen chicken livers imported from different origins, which are sold in the local markets of Baghdad, the lead level ranged between (0.1470- 0.3768) μg/g, fresh weight of liver for local and Brazilian, respectively, and for the copper element (0.5032 - 1.8351( μg/g for the local and Brazilian, respectively, and the level of zinc ranged between (3.2890-4.1016) μg/g for the Brazilian and local, respectively, and the level of cadmium was (0.0031-0.1230) μg / g for the Brazilian and local liver, respectively, While the results showed the levels of mycotoxin residues (AFB1: Aflatoxin B1, AFB2: Aflatoxin B2, AFG1: Aflatoxin G1, AFG2: Aflatoxin G2) for liver samples under local study (1.35, 1.86, 1.02 and 0.91) μg/kg, respectively, for AFB1 toxins., AFB2, AFG1 and AFG2, and they reached (1.53, 1.35, 1.10 and 0.83) μg/kg in the Turkish liver, respectively, while in the Brazilian it showed (1.73, 1.62, 1.22 and 0.97) μg/kg.
