Different extraction techniques and clean-up applied to antibiotics in meat were compared. The quality parameters were established according with EU guideline. The developed method was applied to 49 positive raw milk samples from animal medicated with different antibiotics; the 63% of the analyzed samples were found to be compliant. ___________________________________________________________________________________________ Quinolones Penicil·lina Teixits (Histologia) Llet Cefalosporines Quinolone antibacterial agents Penicillin Tissues Milk Cephalosporines Residues of b-lactams and quinolones in tissues and milk samples.
