Untersuchungen zu DON-Gehalten in Getreideerzeugnissen aus dem deutschen Einzelhandel im Jahr 2006

Samples of soft wheat flour (n=78), durum wheat semolina (n=6), and pasta (made from durum wheat, n=49) were purchased in January-April 2006 from retail outlets in Hesse, Germany. Samples were analysed for deoxynivalenol (DON) by enzyme immunoassay. The detection limit of the method was 10 μg/kg, with recoveries of 81–85% (RSD_r: 12–17%). DON was detected in 84% of all samples, but the contamination level was low. Median/maximum values for DON in wheat flour, wheat semolina, and pasta were 28μg/kg/217 μg/kg, 38μg/kg/203 μg/kg, and 24μg/kg/119 μg/kg, respectively. Compared with results obtained from previous years, significantly lower DON levels were observed in these commodities.
