VICH GL23: Studies to evaluate the safety of residues of veterinary drugs in human food: genotoxicity testing - Revision at step 9, for implementation at step 7
In order to establish the safety of veterinary drug residues in human foods, a number of toxicological evaluations are recommended, including investigation of possible hazard from genotoxic activity. Many carcinogens and/or mutagens have a genotoxic mode of action and it is prudent to regard genotoxicants as potential carcinogens unless there is convincing evidence that this is not the case. Additionally, substances causing reproductive and/or developmental toxicity may have a mode of action that involves genotoxic mechanisms. The results of genotoxicity tests will not normally affect the numerical value of an acceptable daily intake (ADI), but they may influence the decision about whether an ADI can be established. The objective of this guideline is to ensure international harmonization of genotoxicity testing.

Revision 2
Draft VICH GL23 Studies to evaluate the safety of residues of veterinary drugs in human food: genotoxicity testing - Revision 2
This Guideline has been developed by the appropriate VICH Expert Working Group and is subject to consultation by the parties, in accordance with the VICH Process. At Step 7 of the Process the final draft will be recommended for adoption to the regulatory bodies of the European Union, Japan and
USA.
