Abstract
Milk samples from 28 cows were analysed for residues of oxacillin after dry ing off with Stapenor(R) Retard TS (oxacillin). Analysis was performed with an automated HPLC system consisting of an on-line solid-phase extraction a nd photochemical post-column derivatization with UV-detection at 300 nm. Al though the time interval between treatment and parturition was less than th e demanded 55 days, the maximum residue limit of 30 mu g kg(-1) was only ex ceeded in one case, in which the withdrawal time was 28 days.
