This study examined potentially toxic elements (PTEs) from poultry feeds. The presence of PTEs in the environment raises health concern because these elements can be toxic, ubiquitous and cannot be degraded to non-toxic forms by any known method and as a result remain in the environment for decades. This is a potential pathway through which these PTEs could easily enter the food chain. Six PTEs (Cd, Cr, Cu, Pb, Mn, Ni and Zn) were determined from four feed types (starter, grower, finisher and layer) from four manufacturers coded A, B, C and D. The samples were prepared, digested and analysed for PTEs using atomic absorption spectrophotometer. The mean concentrations obtained were in the following ranges: 0.49 – 0.76 mg/kg (Cd); 11.9 – 7.90 mg/kg (Cr); 5.10 – 7.91 mg/kg (Cu); 7.17 – 9.47 mg/kg (Pb); 26.9 – 34.9 mg/kg (Mn); 3.80 – 6.50 mg/kg (Ni) and 27.8 – 38.4 mg/kg (Zn). These results were compared with the maximum acceptable concentration for PTEs in feeds as stipulated by the European Union standard and the concentrations of Pb and Ni exceeded maximum acceptable concentration. When concentrations exceed set standard, it implies risk to human health. Thus, the need for continuous monitoring of feed compositions.
