Abstract This study has evaluated microbiological and toxicological qualities of water of watering in Cotonou. A pilot site at Glo-Djigbé, the market-gardening sites of Houeyiho, Fidjrosse and Agongbomey were included in the work. The salmonellas, Escherichia coli and cadmium were required in water of watering. On the whole, eight water samples of water were analyzed. Water of watering of the pilot site of Glo-Djigbé is not contaminated by Escherichia coli compared to those used at the sites of Houeyiho; Fidjrosse; Agongbomey. Cadmium is absent from all the samples. The study has showed that waters of watering used in urban agriculture in Cotonou are not good and could contaminate the culture, what could induce some diseases with populations. * Corresponding Author: TV Dougnon victorien88@hotmail.com Dougnon et al.
