Europol, the European Union’s police office, executed a large seizure of counterfeit pesticides in December, 2015. The operation was code named Operation Silver Axe and led to the seizure of 190 tons of illegal and counterfeit pesticides. Most of the counterfeit pesticides in the European Union are imported and account for a problem that is believed to be as high as 10% of the pesticides used in the EU.
