Ochratoxin A (OTA) is among the priority contaminants of grape wines. OTA has an expressed toxic (mainly with damage to the urinary system) action, associated, as a rule, with the long-term supply of toxin with food. International Agency for the Study of Cancer, OTA is classified as a substance possibly carcinogenic to human being (group 2B). The average content of OTA in wine, calculated by JECFA experts as a result of analysis of data from studies conducted in the world, was 0.32 �g / kg. At the same time, a higher level of toxin (0.4 �g / kg) was found in red wine than that in white wine (0.1 �g / kg). Currently, Russia does not have hygienic regulations on the content of OTA in grape wines. In EU countries, the maximum OTA content in wines should not exceed 2 �g / kg. The aim of this work was to study the content of OTA in grape wines, presented on the territory of Russia. The presence of ochratoxin A (OTA) Mycotoxin in 26 samples of dry, semi-sweet and dessert grape wines of domestic and foreign production, bought in a retail trade in Russia has been studied. Using the high effective liquid chromatography with tandem mass spectrometric detection, OTA has been found in 8 (31 %) from 26 wine samples studied in an amount from 0.14 to 0.64 μg / l (average content is 0.25 μg / l; median � 0.21 �g / l). The predominant contamination of OTA in the red wines, as well as in the semi-sweet and dessert wines is shown. The results of the study indicate the presence of ochratoxin A in the grape wines presented on the territory of Russia, that requires to exercise the appropriate control by manufacturers and supervisory authorities.
