Assessment of pesticide residues in vegetables produced in central and eastern Ethiopia

Background In Ethiopia, pesticides are widely used in vegetable production. However, if incorrectly they may harm consumers of vegetables contaminated with pesticide residues, as well producers handling the and lead to ecological damage. We performed a cross-sectional survey assess residues produced central eastern Ethiopia. Methods A total 232 samples (91 tomatoes, 106 cabbages 35 Swiss chard) were collected from fields retail markets, screened for (16 organochlorine, 11 organophosphate, 3 pyrethroids, 2 carbamates other agrochemicals) using GC–MS analysis. Results Pesticides detected 60% chard, 47% cabbage 45% tomato samples. Two or more 20% cabbages, 13% tomatoes over half chard Bendiocarb, diazinon, endrin, piperonyl butoxide, profenofos propargite detected, but only had residual values above EU Maximum Residue Level (MRL), diazinon commonly at relatively high levels. About 15% analyzed samples, 10% nearly concentration exceeding MRL. none tested Codex Alimentarius Commission (Codex) MRLs. Conclusion This study showed widespread contamination pesticides, mainly organophosphates. recommend monitoring regulation usage, promotion good agricultural practices.
