The aim of the survey was to determine the possibility in increasing sales of organic food in supermarket stores. The research was done in Wrocław in 2006 on the example of four stores in the supermarket chain "Społem" PSS "Północ". Results of the research confirm that there are possibilities to increase the demand for organic food in about 40%, on condition that some marketing operations are implemented to enlarge the "organic awareness" of the customer and to widen the assortment of offered products. The supermarkets' management staff show a big interest in the problem and are eager to use the survey results while implementing the "Organic Program" in supermarkets "Społem" chain.
