Counterfeiters have been painting expired olives to sell them

A sting operation in Italy has yielded an unlikely cache of loot: over 85,000 tonnes of freshly painted green olives that police just seized from food counterfeiters. The Guardian reported on the newest trick forgers are employing to fake out olive-eaters: a coating of copper sulphate, a plant fungicide considered so unlikely to be used for that purpose that no one was even bothering to test for it.
