For the simultaneous identification and quantification of five nitrofurans metabolites in farmed shrimp and fish, 3-amino-2-oxazolidinone (AOZ), 3-amino-5-morpholinomethyl-2-oxazolidinone (AMOZ), 1-aminohydantoine (AHD), semicarbazide (SEM), and 3,5-dinitrosalicylic acid hydrazide (DNSH), an accurate, precise, and specific method was developed. The mixture of water and methanol (60/40; v/v) was found to be the final optimised solvent for injection. The analytical run duration was 7 min, and the mobile phase included 2 mM methanol and ammonium formate. The new reference point for action (RPA) of 0.50 µg kg-1 as per EC/1871/2019 was taken into consideration and evaluated for the performance characteristics as per the CIR (EC)/2021/808 criteria. Specificity, relative retention time (≤0.25%) relative ion ratio (≤40%), linearity (0.25 to 2.0 µg kg-1), trueness (between 82.8 and 118.1%), repeatability (RSDr ≤14%), within lab reproducibility (RSDwr ≤16.9%), CCα (0.32-0.36 µg kg-1), ruggedness and relative matrix effect (≤14.26%) achieved acceptable values.
