The town of Korhogo (northern Côte d’Ivoire), is supplied with fresh vegetables by vegetable producers in the urban market gardens around the drinking water reservoir. Pesticides are used to increase their crop yield and fight against pests. The aim of this paper is to assess health risks resulting from this pesticide use. A survey was carried out among 150 market gardeners, and 15 samples of reservoir water were analyzed to measure two pesticide residues, especially fungicides. The results showed that almost all the vegetable growers are women (95 %). Furthermore, they apply the products without any personal protective equipment (PPE). Herbicides, fungicides, and insecticides were used by 37 %, 19 %, and 44 % of the growers respectively. As the results of the investigation show, 52 % of pesticides used were not recommended for vegetables. Recurrent health problems of the producers include headaches, sneezing (60.7 %), and visual disorders (28 %). The average concentrations in the reservoir water of substances such as ethylene thiourea (24.17 μg/L) and carbendazim (4.4 μg/L) greatly exceed maximum residue limits. The inappropriate methods for distributing and using pesticides and the lack of suitable protective equipment are risk factors for the environment and for the health of the producers and consumers.
