OSM Wart-Milk is a dairy factory located in the historic town of Sieradz, in central Poland. For nearly 100 years, in the picturesque valley of the Warta River, the company has been producing high-quality dairy products by combining long-standing dairy-making traditions with modern technologies. Established in 1926 as a cooperative of local farmers, the factory initially focused on meeting the needs of the regional market, but over time it set itself new challenges and began expanding beyond Poland.

Today, OSM Wart-Milk systematically gains new customers and strengthens its position both on the Polish and international markets. For the past 10 years, the company has been exporting its products to the European Union as well as to Asia. 

Its mission is fulfilled by harmonising high quality, health safety, and competitive pricing of products delivered to domestic and foreign markets. The company’s portfolio includes UHT products, fresh dairy, and milk powder products, all created with a strong commitment to taste, safety, and reliability.
