title: Current incidence of N-nitrosodimethylamine in beers worldwide.
abstract: A range of beers (n = 138) from 42 countries were analysed for the presence of N-nitrosodimethylamine (NDMA) using a chemiluminescence technique with a limit of quantification of 0.1 microg L(-1). The overwhelming majority of samples (79%) did not contain detectable NDMA, and only three samples exceeded 0.5 microg L(-1). No association was found between NDMA content and beer strength, type or geographical origin. It was noted that water can be a potential source of NDMA in beverages.
