Geographical indications and traditional specialities in the European Union

Three European Union schemes of geographical indications and traditional specialties, known as protected designation of origin (PDO), protected geographical indication (PGI), and traditional specialities guaranteed (TSG), promote and protect names of quality agricultural products and foodstuffs. They are based on the legal framework provided by the EU Regulation No 1151/2012 of the European Parliament and of the Council of 21 November 2012 on quality schemes for agricultural products and foodstuffs. This regulation (enforced within the EU and being gradually expanded internationally via bilateral agreements between the EU and non-EU countries) ensures that only products genuinely originating in that region are allowed to be identified as such in commerce. The legislation first came into force in 1992. The purpose of the law is to protect the reputation of the regional foods, promote rural and agricultural activity, help producers obtain a premium price for their authentic products, and eliminate the unfair competition and misleading of consumers by non-genuine products, which may be of inferior quality or of different flavour.

These laws protect the names of wines, cheeses, hams, sausages, seafood, olives, olive oils, beers, Balsamic vinegar and even regional breads, fruits, raw meats and vegetables.

Foods such as Gorgonzola, Parmigiano-Reggiano, Feta, the Waterford Blaas,Herve cheese, Melton Mowbray pork pies, Piave cheese, Asiago cheese, Camembert, Herefordshire Cider, Cognac, Armagnac and Champagne can only be labelled as such if they come from the designated region. To qualify as Roquefort, for example, cheese must be made from milk of a certain breed of sheep, and matured in the natural caves near the town of Roquefort-sur-Soulzon in the Aveyron region of France, where it is colonised by the fungus Penicillium roqueforti that grows in these caves.
