Ethyl carbamate, also known as urethane, is a carcinogen occuring in fermented foods such as bread, cheese, yoghurt and most in alcoholic beverages, especially in stone fruit brandies. 15 samples of fermented foods were analyzed in this work (2 samples of bread, cheese and yoghurt and 9 samples of alcoholic beverages) using gas chromatography. 5 samples were positive. Ethyl carbamte was detected in all of 3 samples of plum brandy in concentrations (9,94 +- 0,25) mg/l, (5,34 +- 0,41) mg/l and (4,03 +- 0,36) mg/l and in 2 vodka samples in concetrations (2,38 +- 0,25) mg/l and (0,26 +- 0,01) mg/l. Ethyl carbamate was not detected in bread, cheese and yoghurt samples as well as in Gin, Stará myslivecká, Apricot brandy and Gieroy vodka. However, the storage conditions of all samples were unknown.
