中文摘要：赤霉病是一种重要的小麦病害，主要由禾谷镰刀菌引起。除直接危害作物、质量降低及减产外，受感染的麦粒还会积累霉菌毒素（真菌生长产生的有毒代谢物），特别是脱氧雪腐镰刀菌烯醇（DON）。2014/2015年巴西南部的小麦感染了严重的赤霉病。在这样的背景下，本研究旨在评估巴西小麦粒及小麦制品（面粉及麦麸）中DON的真菌毒理学质量。研究表明，鉴于小麦是一种广泛用于食品加工的原料，而DON能引起严重的公共健康危害，因此应该对小麦及其制品中的DON污染进行研究。
外文摘要：Fusarium head blig。ht is an important disease occurring in wheat, caused mainly by the fungus Fusarium graminearum. In addition to direct damage to crops, reduced quality and yield losses, the infected grains can accumulate mycotoxins (toxic metabolites originating from prior fungal growth), especially deoxynivalenol (DON). Wheat crops harvested in 2014/2015 in southern Brazil were affected by high levels of Fusarium head blight. In this context, the aim of this study was evaluate the mycotoxicological quality of Brazilian wheat grains and wheat products (wheat flour and wheat bran for DON. DON contamination was evaluated in 1,504 wheat and wheat product samples produced in Brazil during 2014. It was determined by high performance liquid chromatograph fitted to a mass spectrometer (LC-MS / MS). The results showed that 1,000 (66.5%) out of the total samples tested were positive for DON. The mean level of sample contamination was 1047 µg.kg-1, but only 242 samples (16.1%) had contamination levels above the maximum permissible levels (MPL) - the maximum content allowed by current Brazilian regulation. As of 2017, MPL will be stricter. Thus, research should be conducted on DON contamination of wheat and wheat products, since wheat is a raw material widely used in the food industry, and DON can cause serious harm to public health.
