Spódzielnia Mleczarska "Mazowsze" has its origins in the 1930s. A new dairy facility was constructed in 1966, and it was later extended and upgraded beginning in 1995. SM "Mazowsze" presently includes the towns of Czarnia, Krzynowoga Maa, Jednoroec, Krasne, and Dzierzgowo in addition to the cities of Chorzele and Przasnysz. It runs all across the Przasnysz neighborhood and in small portions of the Ostroka, Ciechanów, Mawa, and Szczytno neighborhoods.
One of the few significant companies in the area. It currently has a cheese packaging line and a cutting-edge, fully automated production base. 90% of the production is sold to markets abroad. The cooperative is in the group of Polish plants that were the first in the country to acquire the European Union accreditation for the export of their products to the European Union countries. They engage in both intracommunity trade and sales outside the EU.
