CVM GFI #257 (VICH GL57) Studies to Evaluate the Metabolism and Residue Kinetics of Veterinary Drugs in Food-Producing Species: Marker Residue Depletion Studies to Establish Product Withdrawal Periods in Aquatic Species
- Docket Number:
- Issued by:
Guidance Issuing OfficeCenter for Veterinary Medicine
The objective of this guidance is to provide study design recommendations that will facilitate the universal acceptance of the generated residue depletion data to fulfill the national/regional requirements for drugs intended for using in aquatic food-producing species.
This document is an extension to the parent residue guidance: CVM Guidance for Industry (GFI) #207/VICH GL48, “Studies to Evaluate the Metabolism and Residue Kinetics of Veterinary Drugs in Food-producing Animals: Marker Residue Depletion Studies to Establish Product Withdrawal Periods.” This guidance, VICH GL57, provides recommendations on what should be included in a marker residue depletion study design for aquatic food-producing species.
Metabolism studies based on CVM GFI #205/VICH GL46, “Studies to Evaluate the Metabolism and Residue Kinetics of Veterinary Drugs in Food-producing Animals: Metabolism Study to Determine the Quantity and Identify the Nature of Residues,” can be used in aquatic food-producing species to identify a marker residue.
