VICH GL23 Studies to evaluate the safety of residues of veterinary drugs in human food: genotoxicity testing - Scientific guideline

This document aims to ensure international harmonization of genotoxicity testing. It recommends a standard battery of tests that can be used for the evaluation of the genotoxicity of veterinary drugs.

Keywords: VICH, consumer safety, genotoxicity testing, residues of veterinary drugs in human food

Current effective version

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

AdoptedReference Number: EMA/CVMP/VICH/526/2000Summary:

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.
