Moroccan olives imported into Spain were found to have an excessive presence of the unauthorized insecticide Chlorpyrifos, which is banned in the EU. The olives contained a proportion of 0.067 mg/kg-ppm of Chlorpyrifos, while the maximum residue limit is set at 0.01 mg/kg-ppm. The Spanish Ministry of Agriculture has approved the withdrawal of Chlorpyrifos-based formulations in certain crops.
