Objects and research methods: the research conducted in 2010-2011 was executed with the use of a standardized inquiry questionnaire on a sample of 224 randomly picked citizens of Krosno. Results: Respondents declaring the purchase of organic food, most often upon its purchasing, pay attention to price and expiry date.

Almost all the respondents were at least content with the purchased organic food. Conclusions: 1. For citizens of Krosno, the availability of organic comestible food is limited by its high price and also by the fact that they are not on offer of stores in which respondents do the shopping most often. 2. The important factors influencing the increase in purchasing organic food are said to be the consumer’s greater awareness and advertisement.
