This standard specifies the three sulfonamides in animal-derived foods: trimethoprim (DVD), trimethoprim (TMP), and trimethoprim (OMP). Sample preparation and liquid chromatography-mass spectrometry/mass spectrometry detection methods for active agent residues. This standard applies to trimethoprim and trimethoprim in muscles (pork, chicken), offal (pork liver, beef kidney, chicken liver), beef fat, eggs, fish, milk and bee products (honey and royal jelly) Determination and confirmation of the residual amounts of three sulfonamide synergists: aminopyridine and dimethoxymethylbenzylamine.
