The U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) has published an updated version of the FSIS Guideline for Residue Prevention. The updated guidance document replaces the 2013 version.

The guideline provides information to establishments that slaughter livestock and poultry about how they can meet FSIS requirements regarding violative residue prevention. It was updated in response to askFSIS questions received since the previous version. The guideline has also been revised to provide updates based on up-to-date science to:

• Incorporate new information on purchase specifications and documentation that can be used to support that violative residues are not reasonably likely to occur
• Address FSIS policy for establishments that perform residue testing.

Additionally, the guideline has been updated to clarify how residues influence New Swine Inspection System (NSIS) sorting procedures and FSIS Kidney Inhibition Swab (KIS™) testing procedures. The guideline also includes changes to improve its readability.
