Determination of Heavy Metals and Anti-nutrient Residues in Selected Organs of Bovines Commonly Slaughtered in Federal Polytechnic Mubi, Adamawa State, Nigeria

Abstract

This study was conducted to determine the concentrations of heavy metals (Lead, Chromium, Copper, Cadmium and Zinc) and anti-nutrients residues (phytate and oxalate) in cattle (bovines) organs slaughtered at Federal Polytechnic Mubi, Nigeria slaughterhouse. Different organs (kidney, liver, lungs, heart and spleen) were collected randomly from five different bovines as samples from slaughterhouse and were brought to the laboratory for analysis. All of the heavy metals analyzed were detected with Lead presenting 293.07 ± 163.53 mg/kg in lung, 2.97 ± 0.39 mg/kg Zinc in heart, 0.632 + 0,3724 mg/kg Cadmium, 1.53 + 1.48 2.972 2.97 ± 0.39 mg/kg Copper, 4.0E^-4 ± 2.0E^-4 mg/kg Chromium in liver, while highest concentration 0.63 ± 0.37 mg/kg of Cadmium and 1.53 ± 1.48 mg/kg Copper was found in spleen. The concentrations of Lead, Zinc, Copper, Cadmium and Chromium detected exceeds the recommended maximum acceptable levels proposed by the World Health Organization (WHO) which are Cadmium 0.5 mg/kg, Lead 0.30 mg/kg, Zinc 0.2 mg/kg, Chromium 1.00 mg/kg, Copper 0.1- 0.50 mg/kg. The results from this study indicate that heavy metal toxicity could result from the consumption of organs of bovines (cows) feed within contaminated areas of Federal Polytechnic Mubi, Adamawa State, Nigeria.
