  • Title: [Multi-method for determining residues of chemotherapeutics, antiparasitics and growth promotors in foods of animal origin. 2. Determination of nitrofurans and nicarbazin (dinitrocarbanilide components)].

    Journal: Z Lebensm Unters Forsch; 1986 Oct; 183(4):253-66. PubMed ID: 3788290.
    Abstract:
    Nitrofurans and dinitrocarbanilide are extracted from food according to the multiresidue method and detected by Reversed-phase-HPLC with UV-detection at 360 nm. Records of the UV-spectra confirm the results qualitatively. Possibilities for further confirmation are discussed. Substances in amounts below 0.01 mg/kg can only be determined with particular care. Statistical confirmation of this method and possible problems are mentioned. An interlaboratory collaborative study confirmed the method: furazolidone, furaltadone, nitrofurazone, nitrofurantoin, and nicarbazin (the dinitrocarbanilide containing component) were added to homogenized eggs in amounts of 0.005-0.150 mg/kg. The procedure can be standardized as an official analytical method at a detection limit of 0.005 mg/kg for nitrofurans and 0.01 mg/kg for nicarbazin.
