中文摘要：为了评估瑞士小麦中镰刀菌霉菌毒素的发生情况，利用LC-MS/MS分析了686份来自种植者收获的样品，进行了一项为期八年的调查。研究表明，就镰刀菌毒素而言，大多数瑞士生产的小麦适合人类消费和用于饲料。尽管如此，根据当年的情况，预计可能含有较高的毒素含量，这是种植者、谷物收集中心和食品工业必须处理的问题，以确保食品和饲料安全。
外文摘要：To assess the occurrence of Fusarium toxins in wheat in Switzerland, an eight-year survey was conducted by analysing a total of 686 harvest samples from growers using LC-MS/MS. Between 2007 and 2010, 527 samples were obtained from 17 cantons. Between 2011 and 2014, 159 samples were collected from the canton Berne. The most frequent toxins detected were deoxynivalenol (DON), zearalenone (ZEA) and nivalenol (NIV). The overall mean DON content in all samples was 607 mu g/kg, and 11% exceeded the European limit for unprocessed cereals for foodstuffs (1250 mu g/kg). For ZEA (mean 39 mu g/kg), 7% exceeded the respective limit (100 mu g/kg), and the mean content of NIV (no limit established) was 15 mu g/kg. Between the years, the ratio of mycotoxin-contaminated samples ranged between 52% and 98% for DON, 9% and 43% for ZEA and 0% and 49% for NIV. The yearly mean contents varied substantially between 68 and 1310 mu g/kg for DON, 5 and 56 mu g/kg for ZEA and 6 and 29 mu g/kg for NIV. The geographic origin showed a significant effect on DON and ZEA contamination, but was inconsistent between the years. This study has shown that the majority of Swiss-produced wheat is, in terms of Fusarium toxins, fit for human consumption and feed purposes. Nevertheless, depending on the year, high toxin contents can be expected, an issue that growers, cereal collection centres and the food industry have to deal with to ensure food and feed safety.
