Analytical Methods for Trichothecenes Surveillance — An Overview Over the Period 1990—2000

This article reviews some aspects of analytical methods used to determine the occurrence of type A and B trichothecenes in grains and foodstuffs and their trends during the decade 1999—2000. A pronounced tendency to use extraction solvents less toxic than chloroform became evident. There was not a p...

Taking into account the mean values of contamination found in the literature and the provisional maximum tolerable daily intake, a methodology suitable for a surveillance work should have a limit of quantification not greater than 50 μg/kg for deoxynivalenol and less than 10 μg/kg for T-2 and HT-2 toxins.
