Abstract— The levels of Organochlorine pesticide residues in the blood and urine samples of Cattles in some selected areas within Kaduna metropolis in Nigeria were determined using standard methods. The results revealed the presence of alpha-lindane, delta-lindane, Dichlorodiethyldichloroethylene (DDE), Dichlorodiphenyldicloroethane (DDD)and endosulfan. In the blood, Alpha-lindane, delta-lindane, Dichlorodiethyldichloroethylene (DDE), Dichlorodiphenyldicloroethane (DDD) and endosulfan were detected at concentrations of 2.06 mg/kg, 2.23 mg/kg, 1.84 mg/kg, 1.94 mg/kg and 0.32 mg/kg respectively. In the urine samples, alpha-lindane, delta-lindane, DDD and endosulfan were detected at concentrations of 0.03 mg/kg, 0.03 mg/kg, 0.01 mg/kg and 0.38 mg/kg respectively. The levels of some of the detected organo-chlorine pesticides residues were above permissible limit of 0.01 mg/kg approved by European Union (EU) and therefore pose threats to the lives of human beings by causing some harmful diseases such as cancer, birth defect and respiratory problems.
