[Evaluation of processing suitability of bread cereals in official responsibility]

In the annual national survey ('Besondere Ernteermittlung') the quality of German cereals was analysed. The samples for this approach were collected from statistically selected fields. One of the analysed parameters was the content of mycotoxins. Thus, it was possible to get an area-wide survey of the content of mycotoxins under natural growing conditions. In 2003 a total number of 974 samples were analysed consisting of wheat, rye and barley samples. A special mode of choosing the wheat samples ensured also a statistically validated result for the federal states of Germany. In the year 2003 the content of the mycotoxins DON and ZEA in wheat and rye samples was lower than in 2002 referred to the median. On the other hand the frequency of detection of DON was not reduced. In barley, which was analysed for the first time in this kind of study, the level of DON was in between the levels of wheat and rye.
