The study was carried out on tomatoes (Lycopersicon esculentum P. Mill) and cabbages (Brassica oleracea L. var capitata) grown in Daloa. It covered ninety samples of vegetables including 60 tomato samples and 30 samples of cabbage collected during three field campaigns in a locality in Côte d'Ivoire (Daloa). These samples were processed using a SHIMADZU brand liquid chromatograph to determine pesticide residues. The results revealed contamination of tomatoes (Lycopersicon esculentum P. Mill) and cabbages (Brassica oleracea L. var capitata). Four pesticide residues, three of which belong to the organophosphorus family (chlorpyrifos, dimethoate, profenophos) and one from the pyrethroid family, were detected in tomatoes with detection percentages of 39%, 25%, 22% and 14%. The results of the analysis also showed the presence of four other pesticides including two from the organophosphorus family (profenophos and diazinon) and two others from the Carbamate family (carbaryl and dithiocarbamate) in cabbages with a rate of detection of 10% and 27%, 10% and 53% respectively. However, the remaining pesticide levels detected in tomatoes and Daloa cabbages are all below the Codex Alimentarius Standards (MRLs).
