      abstract = {This study was carried out to assess the heavy metal contamination in three popular sources of animal protein in Owo, Ondo state, Nigeria. Samples of the animal feeds, chicken meat (muscle, liver, gizzard), pork (liver, muscle and kidney) and catfish were purchased at the distribution centers aseptically and immediately transported to the Laboratory for analysis. The respective animal parts were cleaned and washed with deionized water and then pulverized with pestle and mortal. The samples were ashed and extracted in heated aqua regia followed by filteration and heavy metals were assessed using Atomic Absorption Spectrophotometer. The results revealed that Cu ranged between 0.14 (PM, CM, CG) and 0.21 (PL) mg/Kg, Co ranged between 0.02 (PM) and 0.07 (CFF) mg/Kg whereas, Cr ranged between 0.05 and 0.65 mg/Kg. Also, Cd ranged between 0.03 and 0.10 mg/Kg in the meat samples, Mn ranged between 0.09 and 0.31 mg/Kg while Ni ranged between 0.04 and 0.15 mg/Kg in the meat samples. Moreover, Fe concentration in the meat samples ranged from 0.21 to 1.12 mg/Kg, Mg ranged between 4.72 and 13.1 mg/Kg while Pb ranged from 0.03 to 0.07 mg/Kg whereas, Zn ranged between 0.78 and 1.49 mg/Kg. These results reveals a safe level of heavy metals in pork, chicken, and catfish in Owo},
