Consultation on revised VICH guideline 23: Studies to Evaluate the Safety of Residues of Veterinary Drugs in Human Food: Genotoxicity testing (step 4)


The online consultation is now closed. The content found on this page is a snapshot of the live consultation as it was presented to the public and contains the content that was open for submissions during the consultation period.

VICH (International Cooperation on Harmonization of Technical Requirements for Registration of Veterinary Products) is a trilateral (EU-Japan-USA) program aimed at harmonizing technical requirements for veterinary product registration. Canada (along with Australia and New Zealand) is an observer country at VICH, and the Veterinary Drugs Directorate (VDD) is the VICH Coordinating Secretariat for Canada. The VICH Guidelines provide assistance to industry and healthcare professionals on how to comply with the Government of Canada's policies and governing statutes and regulations. They also serve to provide review and compliance guidance internally, thereby ensuring that the policies and guidelines are implemented in a fair, consistent and effective manner. Before VICH guidelines are adopted or moved to the next step in the adoption process, they are usually submitted to each participating country's industry for consultation and comments on the draft guideline. The VDD has adopted 37 of the VICH guidelines for implementation in Canada.

The objective of this guideline is to ensure international harmonisation of genotoxicity testing.

In comparison with the original VICH guideline 23, which was adopted for implementation in Canada in October 2004, the revised document provides further clarification and specificity regarding the types of genotoxicity studies required. It also removes regional-specific test preferences in an effort to further harmonize genotoxicity requirements.
