Today, human health has been adversely exposed to many inauspicious threats due to human activities. Evidently, ecotoxicological studies documented that industrial and agricultural wastes tremendously contribute to the contemporary environmental pollution. Meanwhile, the application of tannery sludge as fertilizer has been recently reported in Dawakin Kudu LGA of Kano State, Nigeria and this sludge was suspected to have contained a large quantity of toxic metals. This study was aimed to investigate the presence of toxic metals including Cd, Cr and Pb in the fruits of Tomato (Lycopersicon esculentum) grown with tannery sludge in the selected farms in the study area in order to ascertain their suitability for human consumption. The toxic metals (Cr, Cd and Pb) were found to be incorporated into the tissue of tomato
