Abstract: The city of Daloa located in the center-west of the Ivory Coast chief town of the Haut-Sassandra region since 1996 has a significant market gardening activity in the slums of the districts of ABATTOIR, COMMERCE CIE, ORLY, MARIN, COMMERCE CROU D and HUBERSON. A study from May 2017 to August 2017 in this geographical unit, had as main objective to determine the level of microbiological contamination of wastewater used in market gardening, to evaluate the health risk for fresh vegetables and to contribute to the reduction of negative impacts induced. It emerges that the water of the Daloa town's lowlands used for watering plants is polluted by wastewater and solid waste from households, markets, and have significant levels of streptococci (495 PDUs). / mL at 1.850 x 103 UFC / mL), in Salmonella (2 103 UFC / mL), in E. coli (290 UFC / mL at 1.082 103 UFC / mL), in P. aeroginosa (521 UFC / mL at 1, 26 103 UFC / mL), S. aureus (135 UFC / mL at 360 103 UFC / mL) and V. cholera (95 UFC / mL at 337 UFC / mL). Many practices and numerous risky behaviors have been observed and contribute to the spread of waterborne diseases. Despite the risk of waterborne diseases, this activity contributes significantly to improving the living conditions of the categories of actors involved in this activity.
