Opracowano metodą elektroforetycznego oznaczania pozostałości nifursolu w tkankach jadalnych indyków (mięśnie, skóra z tłuszczem, wątroba i nerki). Przeprowadzono walidacją całej procedury oznaczania nifursolu; limit wykrywalności ustalono na 7 g/kg w badanych tkankach. Przedstawiona metoda jest specyficzna, precyzyjna, czuła i wystarczająco dokładna do oznaczania pozostałości leków weterynaryjnych w tkankach pochodzenia zwierzęcego.

The use of veterinary drugs (antibiotics, coccidiostatics) to treat animal disease and to promote fast, more efficient growth of livestock is a common practice in modern agriculture. In order to protect the health of the consumer of foodstuffs of animal origin, one of the most important principles laid down in the legislation is that foodstuffs obtained from animals treated with veterinary medicinal products must not contain residues of the medicine or its metabolites which might constitute a health hazard for the consumer. One of the most common anticoccidial drug used in EU to 2003 was nifursol. The aim of this study was to develop a confirmatory analysis by capillary electrophoresis (CE) for nifursol residues in edible tissues (muscle, skin with fat, liver and kidney) of turkey origin. The whole of nifursol determination procedure was validated. The described method is specific, sensitive, precise and accurate enough for determination residue of veterinary drugs in tissue of animal origin and could be used for therapeutic drug monitoring.
