A multianalyte method, using a MS/MS detector, was applied for a simultaneous determination of 23 mycotoxins in 64 beer products purchased from the supermarket in Lleida, Spain. The samples varied by their origin, brewing technology, alcohol content, etc. The results showed that 20.3% of the tested samples were mycotoxin contaminated overpassing the limit of detection (LOD). None of the alcohol-free samples (17%) were contaminated with mycotoxins. The most frequently occurring toxin was zearalenone (ZEN), being quantified in 65% of the positive samples, with levels ranging from 8.24 to 62.96 μg/L. Regarding the co-occurrence of mycotoxins, three samples were found to contain two or more mycotoxins simultaneously. A deterministic approach was used to evaluate the contribution of beer consumption to daily intake and the proportion of the established tolerable daily intake (TDI) for ZEN and deoxynivalenol (DON) and its metabolite deoxynivalenol-3-glucoside (DON-3-G).

应用MS / MS检测器的多分析物方法同时测定了从西班牙莱里达超市购得的64种啤酒产品中的23种霉菌毒素。样品因其来源，酿造技术，酒精含量等而异。结果表明，被检测样品中有20.3％被霉菌毒素污染，超过了检测限（LOD）。无酒精样品（17％）没有被霉菌毒素污染。最常见的毒素是玉米赤霉烯酮（ZEN），在65％的阳性样品中定量，含量范围为8.24至62.96μg/ L。关于霉菌毒素的共存，发现三个样品同时含有两种或更多种霉菌毒素。
