From the total of collected targeted samples, 40.9 % were analysed for substances having anabolic effect and prohibited substances (group A) and 63.1 % for veterinary drugs and contaminants (group B).
The residue situation in 2009 was similar to the two previous years for all substance groups. However, because the sampling plan and the spectrum of analysed substances were not necessarily the same over the three years, such comparisons should be regarded as having a high degree of uncertainty.
