The present study provides information on the concentrations of metals in liver, stomach, intestine, colon and kidney of animals. These entrails of cow, sheep and goat are delicacies in this part of the world. Many Nigerians (Men and Women) in their 40s, prefer these delicacies (internal organs of the animal) whenever they visit local restaurants or purchase beef (meat) for consumption at home. They are becoming exposed to these toxic metals. The heavy metals determined in this work are Pb, Cr, Cd, Cu and Co. PB was consistently higher in all samples analyzed. In all the samples analyzed, the ranged from 6.116 to 15.110 mg/kg in the goat, 8.018mg/kg to 11.617 mg/kg in the cow and 9.969 mg/kg to 21.614 mg/kg in the stomach of sheep, Co has the lowest concentration ranging from 0.960 mg/kg to 8.169 mg/kg in all the samples analyzed. All the animals (cow, goat and sheep) samples contained heavy metals, exceeding the WHO guidelines for permissible tolerable weekly intake (PTWI).
