Fusarium toxins in cereals grown in Switzerland

摘要

770 cereal samples of Swiss origin which were collected in various feed mills and cereal collection centres in the years 2000 – 2002 were assayed for Deoxynivalenol (DON) and zearalenone (ZEA). 137 samples were also assayed for T-2 toxin. The prevalence of DON and ZEA contamination was higher in cereals harvested in the rainy summer 2002 than in the previous years. T-2 toxin levels exceeding 100 µg/kg were found only in three oats samples. High levels ofFusarium toxins do not frequently occur in Swiss cereals.
