Residues from veterinary drugs are a well-known threat to human health. A variety of these compounds are banned for use in food for human consumption and many more are regulated with specific maximum residue limits. As the industry moves to multi-residue screening methods it is imperative that laboratories can conduct analyses of veterinary drugs accurately and efficiently. This is particularly problematic due to the complex nature of veterinary compounds and Reference Materials play a crucial role in mitigating these issues.
In this poster we will present the development process for six multi-component mixtures containing 92 analytes of different classes of vet drugs including Tetracyclines, Sulfonamides, Avermectins, Quinolones, Benzimidazoles and Beta-lactams to support analytical labs screening for these compounds. The stability of all mixtures was intensively investigated through real-time stability monitoring over several years. We will also be exploring the extension of these mixtures including the development of pharmaceutical mixtures for environmental testing.
