A comprehensive review on the pretreatment and detection methods of nitrofurans and their metabolites in animal-derived food and environmental samples

Food Chemistry: X
In recent years, the residues of nitrofurans (NFs) and their metabolites in animal-derived food and environmental samples have gained widespread attention. The parent drugs and their metabolites have displayed significant toxicity to human health including carcinogenic, mutagenic and teratogenic effects, leading to banned in animal husbandry in many ...

[Determination of nitrofuran metabolites residues in animal tissues by LC-MS/MS method].

Roczniki Panstwowego Zakladu Higieny, 2008
A LC-MS-MS method is presented to analyze simultaneously the metabolites of four nitrofuran veterinary drugs in animal muscle tissue e.g., furazolidone, furaltadone, nitofurantoina and nitrofurazone. The sample clean up were performed by a liquid-liquid extraction with ethyl acetate, after a hydrolysis and derivatization with 2-nitrobenzaldehyde ...
