PDO Products, or Protected Designation of Origin products, are food items that are produced, processed, and prepared in a specific geographical area using traditional methods. This designation ensures that the product's quality and characteristics are closely linked to its origin, providing consumers with assurance about its authenticity and origin. Examples of PDO Products include Parmesan cheese, Balsamic vinegar, and Roquefort cheese. These products must meet strict criteria set by the European Union to maintain their PDO status, which helps preserve regional culinary traditions and supports local economies by promoting unique local products.
