Abstract: | A total of 92 samples — 23 winter wheat, 12 summer barley, 5 oats and 52 mixed feed — were collected from a state factory
in Kaunas, Lithuania and were analysed for the presence of trichothecenes, zearalenone (ZEN) and ochratoxin A (OA) using gas
chromatography with electron capture detection and immunoaffinity column/high performance liquid chromatography with fluorescence
and UV detections. Deoxynivalenol (DON), nivalenol (NIV), T-2 toxin and HT-2 toxin were detected at concentrations above 10
μg/kg in 68%, 48%, 38% and 8% of cereal samples, respectively, and in 98%, 88%, 12% and 8% of samples of mixed feed for swine
and poultry. More than 10 μg/kg of zearalenone and ochratoxin A were found in 58% and 92% of the mixed feed samples, respectively.
The highest concentrations of all analysed trichothecenes in Lithuanian mixed feed and cereal grains, with an exception of
T-2 toxin in one oat lot and one sample of mixed feed and OA in two mixed feed samples, were lower than those reported as
Lithuanian advisory or tolerance limits. |
