Abstract

Two international Proficiency Testings (PTs) have been conducted in 2014 for the simultaneous determination of deoxynivalenol, fumonisins, zearalenone, T-2 and HT-2 toxins, ochratoxin A and aflatoxins in maize and of deoxynivalenol, zearalenone, T-2 and HT-2 toxins and ochratoxin A in wheat, respectively, by using LC-MS methods. The overall performance of participating laboratories to the PTs and the trend in multi-mycotoxin determination by LC-MS in maize over the years 2011-2014 are presented.
