Origin of one of the largest and most modern milk processing enterprises in Lithuania – ŽEMAITIJOS PIENA companies – starts in 1924. According to the legend, the Telšiai milk factory, which was founded by giant DŽIUGAS in the old town of Samogitia, built in the ancient countryside, in the ancient city of Telsiai, was, quite a century ago, quite large capacity: it produced butter, cottage cheese, cream and other dairy products.Over the years and in consultation with the best European and US firms, focusing on the introduction of new technologies using Bactocath’s world-leading membrane-based milk treatment technology, has expanded the range of products produced and improved their quality. In 1995, the State Veterinary Service of the Republic of Lithuania, after verifying the LACTIC MILK, established that the company complies with the veterinary requirements and issued the State Veterinary Surveillance Number EN 78-01 P. 20 04 1995, Order No. 4-104 “On the Issue of Veterinary Care Numbers”. In mid-2009, the company was awarded ISO 9001 Quality Management and ISO 22000 Food Safety Systems Certificates. They were also received by the company “Klaipėdos pienas” and “Šilutės Rambynas”. Under the self-control system installed, the company strictly controls the raw material, production processes and performs laboratory testing of the finished product. Everyday research is carried out in the Independent Research Laboratory, which in 2006 was the first food industry laboratory in Lithuania accredited by the German accreditation bureau DAkkS in accordance with international standards LST ISO / IEC 17025.
