Our cooperative

is an association bringing together neighbours, both near and far, who share a common goal: to provide people with high quality, natural dairy products.



Local dairy production is steeped in old farming traditions which have been thriving for centuries in the fertile valley of the River Narew.

  • Cows of the Lutosławski family

    The Lutosławski family (from which the famous composer originated) was once established in Drozdowo. The family imported dairy cows to their estate and founded the first local creamery. For decades, its members continued to deliver premium quality products to the city of Łomża.

  • Lickety-split – off we go to Łomża

    After the war, the creamery was relocated to Łomża. It specialised in the production of butter (180 tonnes a year) and cheese (30 tonnes a year). The facility was growing dramatically and in just five years boosted its employment from just nine to 74 staff members.

  • Let’s give it to the people

    The dairy plant was transformed into the Regional Dairy Cooperative in Łomża. Due to its worn and torn machinery and dilapidated building, several years later a decision was made to erect a new building for the cooperative. But where?

  • Welcome to Piątnica!

    A new site for the facility was found in Piątnica, where the milk processing plant launched its operations under a new name: Okręgowa Spółdzielnia Mleczarska in Łomży with its business seat in Piątnica. At the time, it employed 94 people and processed 14 million litres of milk a year.

  • OSM Piątnica, hello!

    This is when our cooperative was finally established. We are committed to the Łomża region for better and worse; we support local breeders and farmers, and play a pivotal role in our community. And that’s good, because together we can do more and perform even better.

  • The first big thing!

    We were the first in Poland to launch Cottage Cheese, which continues to be the most-loved cheese across our country. Ever since that time, we have been relentlessly seeking new solutions in the universe of dairy products, while staying true to our tradition and integrity.

  • Teaming up with Ostrołęka

    We merged with the “Ostrołęka” Dairy Cooperative, which has now been renamed as the OSM Piątnica Production Facility in Ostrołęka. As a result, we were able to expand our product range and enhance it with certified organic milk, and much more.

    The Iconic Cottage Cheese

    It has been with us since 1992. This product has garnered multiple awards for its flavour and quality, and Poles have fallen head over heels for it. It’s a pioneer in the cottage cheese category and the enduring number 1 in our country.

    Jolly good cream

    We are famous for our reliable sour cream with 18% fat content, which doesn’t curdle in soups. We were the first in Poland to introduce standardised cream packaging (readily available 200 g cups), colour codes as well as tips and advice on how to use the product.

    Our recipe for curd cheese

    We pioneered sales of curd cheese with a fixed weight and price, which comes in durable open and close packaging. Soon after, this solution gained a foothold not only in Poland, but also beyond!

    Piątuś. Yoghurt for children

    In 2015, we were the first in Poland to launch nutritious Greek-style yoghurt in a version designed for children. Its main draws are a simple formula and delicious fruity flavour. It is made of yoghurt and slightly sweetened fruit, while the vanilla version contains specks of ground vanilla bean. Are you already familiar with Piątuś?

    Good and lactose-free

    In 2016, we expanded our range with lactose-free milk, which stands out with unchanged flavour and is packed with nutrients. A year later, we introduced lactose-free Cottage Cheese. We made sure that both of these products have no distinctive sweetish aftertaste, a frequent complaint of those who follow a lactose-free diet.

    From Iceland to Poland

    We were the first in Poland to launch on the market the scrumptious and highly nutritious Icelandic-style yoghurt known as skyr. In addition to traditional thick and dense skyr, we also introduced a handy drinkable version. This Icelandic treat has became a massive success and continues to surge in popularity.

    Uncompromising quality

    We have always been upping the ante in terms of milk flavour and quality. In 2019, we introduced the highest grade of purchased milk, which means that we comply with requirements which are three times more stringent than EU requirements.

    Craving something delicious

    In 2019, we launched traditional fromage frais with natural and simple ingredients and flavour which brings back childhood memories. In addition to classic vanilla flavour, we have also introduced different variants to our range: natural, strawberry, and stracciatella-flavoured fromage frais.

    Wonders of nature
    from Piątnica

    Nutritional smoothies are an innovation launched in 2020. A unique ingredient, or unprocessed, fresh whey protein – the most valuable milk protein – has been blended with fruit to produce a nutritious and scrumptious treat. It must be magic!


Truly committed to quality

We were the first dairy cooperative in Poland to implement the Integrated Management System that covers the ISO 9001 quality management system, the HACCP-based food safety system, as well as the ISO 14001 environmental management system. We also hold an International Food Standard certificate.

Quite simply: we make sure that all our products are produced in an exemplary manner, and we commit ourselves to even more stringent requirements than the EU in terms of milk quality.

people and nature

For years, we have been implementing the Corporate Social Responsibility concept, providing varied support to milk suppliers and taking care of our employees. We also undertake a number of measures to mitigate the negative impact on the natural environment. Learn how all this looks from the perspective of a member of our cooperative – watch the video.
