The Hellenic Livestock Association (SEK) has expressed concerns over the production of counterfeit Protected Designation of Origin (PDO) feta cheese using cow's milk by Greek industries, which is being sold in the EU. This threatens the PDO status of the cheese. The Ministry of Internal Affairs and Communications has initiated checks on all milk and cheese traffic, but SEK deems these measures inadequate. SEK has suggested further safeguarding and certification measures, including the implementation of the ARTEMIS 2 program, banning ultrafiltration in all PDO feta-producing industries, and enforcing stricter penalties for industries that breach PDO production rules.
