• Methods for veterinary drug residue analysis in food

      O'Keeffe, Michael (Teagasc, 1999-02)
      A comprehensive capability to test for residues of veterinary drugs is an important support for the Irish food industry. There is a requirement for food manufacturers to demonstrate the compliance of their products with stringent customer specifications. In addition, legislative requirements are becoming more exacting both in terms of the range of substances covered and the lower residue levels to which test systems must measure.
    • Nitrofurans : measuring tissue-bound residues in meat

      The aims of this project were to (a) develop a range of screening and confirmatory test methods that might be applied to effectively test for the illicit use of the prohibited nitrofuran antimicrobials, (b) study the persistence of nitrofuran antimicrobials as bound metabolite residues in edible tissues and (c) undertake a pan-European survey of the incidence of nitrofurans in retail pork.
    • Rapid control systems for veterinary drug residues in food producing animals

      The aim was to develop rapid systems which could be used to test for the presence of veterinary drug residues in food producing animals. Body fluid samples are most suitable for rapid testing systems so as to avoid the lengthy residue extraction procedures required for tissue samples. Urine was analysed for sulphamethazine, a licensed antimicrobial, and for chlorotestosterone, a prohibited growth promoting agent, as models to demonstrate the different approaches.
