Aims: To determine the concentrations of heavy metals (Cd,
Fe, Mn, Pb, and Zn) in kidney and liver of slaughtered cattle. Study Design: Analytical method. Place and
Duration of Study: Samples obtained from Gwagwalada abattoir in Abuja, Nigeria
and transported University of Abuja, Chemistry Laboratory for analysis. The
study lasted for four (4) months.
Methodology: Wet digestion of samples followed by metal analysis using
Accusys 211 Bulk Scientific Atomic Absorption Spectroscopy (AAS). Results: The
empirical results indicated that the mean levels or concentration of these
heavy metals in kidney of cattle were 47.75±0.002 g/g Zn,
279.5±0.084 g/g Fe, 10.00±0.00g/g Mn, while Cd and Pb were not detected. The
levels or concentration of heavy metals in the liver sample were
0.500=±0.000025 g/g Cd, 57.00±0.0001 g/g Zn,
119.5±0.0016 g/g Fe, 5.75±0.000025 g/g Mn, Pb was not detected. The
concentration of Fe and Mn were found to be high in kidney sample than the
liver sample. Conclusion: The evidence from
this study revealed the safety of these investigated offal meats as the
concentrations of these metals in the kidney and liver samples were within the
maximum permissible limit according to the European Commission (EC) and FAO/WHO
standards.
