Introduction: The occurrence of Fusarium species and their toxins in grain is reported worldwide but little is known about the mycotoxin contamination in straw. This is used in livestock husbandry for litter as well as a forage component. An exposure with contaminated straw can cause diarrhea, vomiting, increased susceptibility to other diseases and decreased performance (1).In the present project, a cooperation of the Institute of Animal Nutrition at the University of Hohenheim and the Institute of Animal Nutrition in the Friedrich-Loeffler-Institute, straw samples are analysed for a spectrum of 13 trichothecene toxins, zearalenone and ochratoxin A over a period of 2 years.Samples are collected by public agencies proportionately to the straw harvested in the different federal states of Germany. First results of the contamination of straw with a spectrum of A-type and B-type trichothecenes are presented.
Materials and Methods: Clean up was carried out by solid phase extraction using a florisil and a cation exchange cartridge. After derivatisation with trifluoracetic anhydride the separation and quantitation was by GC-MS, (2).
Results: Overall, deoxynivalenol was the most prevalent toxin based on occurrence and toxin levels. The B-type trichothecenes nivalenol, 3- and 15-acetyl-deoxynivalenol as well as the A-type trichothecenes scirpentriol, 15-monoacetoxyscirpenol, 4,15-diacetoxyscirpenol, T-2 toxin, HT-2 toxin, T-2 tetraol and T-2 triol have also been found. Only the trichothecenes neosolaniol and fusarenon-X have not been detected. The cooccurrence of up to 9 trichothecenes in one sample was observed.
Discussion and Conclusion: A first insight into the contamination of straw with a broad spectrum of Fusarium toxins is provided.
