The Cooperative commenced its activity in 1926; its founders were members of the Towarzystwo Organizacji Kółek Rolniczych (the Organisation Society of the Circle of Farmers). The first seat of the company was in the cellars of the simple wooden building of the cooperative savings bank, located at the crossroads of Warszawska and Szkolna Streets. In those days, the cooperative bought 120 litres of milk per day and made butter from it. They also ran a dairy shop in Dęblin. Among the people who built the foundations of this business in Ryki were Pruchnicki, Bronisław Warowny, Henryk Skopupko, Antoni Kozak and Andrzej Filipek. And in the years1934-37 there must have been more of such dedicated people as they erected, with their own money and effort, a production plant whose processing capacity was 1200 litres/day.
   Under the German occupation during the Second World War, the firm was kept in operation for a long time by Janusz Wierusz Kowalski, the director. The building was bombed, however, and its roof was destroyed, and it was not until 1948 that it was restored to its former splendour thanks to Mr. Aleksander Rusa. From 1 July 1948 the Cooperative was purchasing eggs and poultry while the daily purchase of milk amounted to 100 litres at the beginning and 500 litres at the end of 1948. The territorial scope of the Cooperative’s activity began to expand quickly. Initially, milk was brought to the dairy in a Russian gazik military car and a second-hand Chevrolet. Thanks to the profits on the poultry and egg trade, the purchase of the cars was quickly amortised and debts could be repaid. In 1950 as much as 2 million litres of milk were purchased. In the fifties, the plant was nationalised. The Powiatowy Zakład Mleczarski w Garwolinie Oddział w Rykach (the District Dairy Enterprise in Garwolin, Branch in Ryki) was called into being. Obligatory milk supplies were introduced. Further transformations in 1954 led to the establishment of the Independent Dairy Enterprise in Ryki in which butter, cottage cheese and maturing cheeses (the so-called yellow cheese) were produced. In 1957 the Dairy Cooperative was reinstated and it experienced considerable development. Milk purchase was continually on the rise: in 1959 it exceeded 10 million litres and in 1965 reached the amount of 12 million litres. However, the processing capacity turned out to be insufficient in the face of the intensive increase of milk supplies. Expansion of the enterprise was considered. Gończyce and Żelechów were striving to win a similar investment too. The location in Ryki was initially on a different site to its current location in Żytnia Street.
   In 1967 the purchase of milk amounted to 15 million litres and in 1971 it reached 17 million. Under these conditions, the building of a new plant was a must. In June 1972 a new modern dairy plant was put into operation. It cost 60 million zloties and its target production capacity was 100 thousand litres per day. Now it was possible to handle all the purchased milk properly. Jan Głodek was the president of OSM Ryki until 1 February 1974. He was succeeded by Stanisław Błachnio, Stanisław Szopa and Mirosław Lusztyk. In 1974-75 the casein plant and a purchasing centre were added. On 2 November 1982 eng. Tadeusz Polański became the president of the enterprise and Tadeusz Łabędzki and Jerzy Pyza, M.Sc. were the vice-presidents. In 1986 the technical warehouse was created and in 1995 the cheese plant became operational - it is entirely automated. At present it is mainly various kinds of maturing cheese that are produced.
   In 1996 the purchase of milk amounted to 43 million litres; 180,000 litres per day at peak periods. In 1997/98 a modern quality control laboratory was put into operation. The laboratory also carries out tests for other dairies for a fee. The expanding cooperative moved its trade division and food warehouse to a new location in the so-called trading area, located in Fabryczna Street (with several other warehouses such as Eldorado and the Hortex production plant nearby).
   In 1998 49.5 million litres of milk were purchased. The Dairy Company in Ryki was developing dynamically and held a leading position among the best dairy companies in Poland. Moreover, in the same year, a new system of cheese salting was introduced and substituted the old system.
   In February 1999 a new production line for whey thickening (based on the reverse osmosis principle) became operational.
   Although we have achieved a lot, the Dairy Cooperative in Ryki wants to continue developing and attracting even more consumers.
