Residue analysis of fipronil and difenoconazole in okra by liquid chromatography tandem mass spectrometry and their food safety evaluation

•An LC–MS/MS method for fipronil and difenoconazole residues is reported in okra.•LOQ was 1ngg−1 for fipronil and its metabolites and 5ngg−1 for difenoconazole.•Fipronil and difenoconazole residues dissipated with PHI of 15 and 4days.•Washing and cooking treatments had significant effect on residue...
