Abstract

The present study was performed to detect the concentration of the toxic heavy metals (lead Pb, cadmium Cd, arsenic As and mercury Hg) in meat and rations of broiler chickens, and their effect on animals and human public health. Seventy samples were collected {40 samples of broiler chickens highly demined by the consumers in Al-Diwaniyah markets, these samples included: 10 samples of each of the Brazilian frozen chicken (Al-kafeel), Turkish frozen chicken (Barakat Al-kadhimian), Iranian frozen chicken (Al-mahdi) and broiler chicken from local breeding, also 30 samples from the poultry final rations highly bought by breeder of chicken in the province which include 10 samples from each of the Al-kadra, Al-waha ratios and ratio which locally manufactured in the Al-Diwaniyah factory}. The thighs and breast muscles of the chicken samples were then separated from the chicken body, while the edible offal (liver and gizzard) for these samples collected from the same sources. Atomic absorption spectrophotometer (England origin) were used to estimate the heavy metals residues. The results showed a significant variances (p≤0.05) for comparative means in the concentrations of the studied heavy metals (Pb, Cd, As and Hg) among examined organs and muscles, generally, the highest concentration was detected in the liver followed by gizzard, then thigh muscle and breast muscle in all examined samples, though, the concentrations stay under permissible standardization limits which recorded by WHO/FAO, European, Gulf Standardization Organization (GSO) and Egyptian organization for standardization and quality control (EOS). In the ratios, the highest concentrations recorded were in locally manufactured ratio followed by Al-Kadra, then Al-Waha ratio, the means also remained under standardization permissible limits allowed by the National research council (NRC) to mineral tolerance in animals feed.
