Introduction:
An attitude consists of specific behaviour conditioned, on the one hand, by knowledge concerning the phenomenon, on the other hand, by individual emotional relationship.

Objective:
The study presents only the behavioural aspect of attitudes of adolescents towards genetic modification of organisms and genetically modified food. The remaining aspects of this attitude – knowledge and emotions, are discussed in other publications [1, 2].

Materials and methods:
The study was conducted on a sample of 500 students completing secondary schools in the Lublin Region. The research instrument was a questionnaire. The collected material was subjected to statistical analysis using SPSS. The relationships were investigated using chi-square test; the level of significance was set at p < 0.05.

Results:
The respondents were against the cultivation of GM crops / breeding of GM livestock on their own farms. In the case of animal breeding, the respondents were against feeding livestock with feed derived from GM plants. According to the respondents, there are no reliable results of research concerning health effects of consuming GMF. They do not trust the food produced on the basis of GMO. The respondents pay increasingly more attention to healthy nutrition. As food consumers, they are willing to pay more for food products free from GM.

Conclusions:
Analysis of the research material showed that adolescents have a relatively sceptical attitude towards genetic modifications and genetically modified foods.
