Abstract

A grand total of 120 random samples of chicken meat products represented by chicken pane, chicken nuggets, chicken sheish tawook and chicken kofta (30 of each) were collected from different super markets at El-Kalyoubia governorate. The collected samples were produced by two different poultry processing plants namely A and B. In other words, each chicken meat product was represented by 15 samples related to the processing plant A and 15 ones related to the processing plant B. The samples were directly transferred to the laboratory for determination of their contents of cadmium, copper and mercury. The obtained results indicated that the mean values of cadmium concentration in the examined samples of chicken pane, chicken nuggets, chicken sheish tawook and chicken kofta were 0.06 ± 0.01, 0.13 ± 0.01, 0.17 ± 0.01 and 0.25 ± 0.02 mg/kg, respectively for plant A. While mean values for plant B were 0.11 ± 0.01, 0.19 ± 0.01, 0.26 ± 0.02 and 0.38 ± 0.02 mg/kg, respectively. Also the obtained results indicated that the mean values of copper concentration in the examined samples of chicken pane, chicken nuggets, chicken sheish tawook and chicken kofta were 1.12 ± 0.08, 1.48 ± 0.13, 0.99 ± 0.07 and 2.03 ± 0.16 at plant A, respectively, and 1.31 ± 0.12, 1.68 ± 0.15,1.24 ± 0.10 and 2.17 ± 0.18 at plant B, respectively. Furthermore, the obtained results indicated that the mean values of mercury content in the examined samples of chicken pane, chicken nuggets, chicken sheish tawook and chicken kofta were 0.015 ± 0.01, 0.17 ± 0.01, 0.22 ± 0.02 and 0.31 ± 0.02 mg/kg at plant A, respectively, and 0.18 ± 0.01, 0 .26 ± 0.01, 0.29 ± 0.02 and 0 .35 ± 0.02 mg/kg at plant B, respectively.
