Banned antibacterial growth promoters in animal feed: Collaborative trial on the liquid chromatography-tandem mass spectrometry method developed in the feedstuffs-radius project

A chemical confirmation method for the identification and quantification of five banned antibacterial growth promoters (AGPs) in animal feed was developed and in-house validated as part of the European Feedstuffs-RADIUS project [1]. To complete the validation process a collaborative trial was performed by eleven laboratories within the European...

Use of biosensors for rapid drug residue analysis without sample deconjugation or clean-up: A possible way forward

The drug salbutamol (SBL) is a β-agonist that may be used illegally as an animal growth promoter. SBL is also a good example of a drug which is excreted in the form of glucuronides and sulfates. Such metabolites cause complexities in analysing for the presence of drug residues. In the majority of cases a process of deconjugation and sample clean...
