Abstract: This article describes a full analytical method for the clean-up and detection of benzylpenicillin in chicken and beef meat samples using a previously developed molecularly imprinted polymer in a solid-phase extraction cleanup step followed by analysis using LC-MS/MS. The method was validated based on the criteria and the requirements of the European Commission Decision 2002/657/EC. This validation revealed method performance characteristics that meet all the criteria in the Decision with limits of detection for chicken and beef meat samples of 6.2 and 14.4 μg/kg, respectively, 8 and 3.5 times lower than the MRL. This method holds strong potential when a specific cleanup of benzylpenicillin is required, because with slight modifications it is also applicable in a milk matrix [1]
