USDA-FSIS Implements Modernized Chemical Residue Quantitative Method for Beef Muscle
The U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) has developed an innovative method for beef muscle samples that uses modern chemistry instrumentation for quantifying chemical residues.
On October 1, 2023, the FSIS laboratory system intends to implement the new quantitative method for veterinary drug residue analysis in bovine muscle samples, titled, “Quantitation of Animal Drug Residues by High-Resolution, Accurate-Mass Liquid Chromatography Mass Spectrometry (HRAM LC-MS)” (CLG-MRQ1). Benefits of the method include the abilities to:
