Protected Designations of Origin (PDO) are labels used in the European Union to identify products that are produced, processed, and prepared in a specific geographical area. This designation ensures that the quality and characteristics of the product are closely linked to its origin, promoting traditional methods and local resources. PDO is commonly applied to food and drink items, such as Parmesan cheese and Champagne. By protecting these designations, consumers can trust that they are purchasing authentic products, while producers benefit from recognition and protection against imitation, helping to preserve cultural heritage and local economies.
