Stung by heavy losses, Italian producers began a campaign today [Friday] for the EU and WTO to take definitive measures against "food-piracy" - imitations of products of "protected origin" but readily available around the globe. At issue are some 550 food products - Italy has over 100 of them - considered by the EU to have Denomination of Protected Origin, but apparently powerless to prevent fakes outside EU, necessitating WTO intervention for any effective global action.
