Natural occurrence of trichothecenes and zearalenone in Korean and imported beers

Food Addit Contam. 1997 Jan;14(1):1-5. doi: 10.1080/02652039709374490.

Abstract

In order to survey the natural occurrence of Fusarium mycotoxins including deoxynivalenol (DON), nivalenol (NIV), and zearalenone (ZEN) in beers consumed in Korea, a total of 54 extracts of Korean and imported beers were derivatized with heptafluorobutyric anhydride and analysed by gas chromatography-mass spectrometry with selected ion monitoring mode. DON was detected in 14 samples (26%) and NIV was detected in 43 samples (80%). ZEN was not detected in any of the samples tested. The incidence of DON was 19% for Korean beers and 50% for imported beers, whereas the incidence of NIV was 85% for Korean beers and 58% for imported beers. This is the first report that the beers consumed in Korea are contaminated with DON and NIV.
