AMOZ is primarily used as a marker residue in food safety testing, particularly in the monitoring of nitrofuran antibiotics in animal products. Nitrofurans, including furazolidone, are banned in many countries due to their potential carcinogenic effects. AMOZ is a metabolite of furazolidone and is detected in tissues, eggs, and other animal-derived products to ensure compliance with food safety regulations. Its detection is crucial in preventing the illegal use of nitrofurans in livestock farming, thereby safeguarding consumer health. Analytical methods such as liquid chromatography-tandem mass spectrometry (LC-MS/MS) are commonly employed to identify and quantify AMOZ residues in food samples.
