Summary

The purpose of this Re-evaluation Decision Document (RRD) is to notify registrants, pesticide regulatory officials and the Canadian public that Health Canada's Pest Management Regulatory Agency (PMRA) has re-evaluated the active ingredients brodifacoum, bromadiolone, chlorophacinone, diphacinone and warfarin and their associated uses as rodenticides.

On 14 July 2004, Proposed Acceptability for Continuing Registration document (PACR) PACR2004-27, Re-evaluation of brodifacoum, bromadiolone, chlorophacinone, diphacinone and warfarin, was published for consultation. The PMRA has reviewed the comments received and provides a response in Appendix I of this RRD. These comments did not result in substantive changes to the regulatory decision as described in PACR2004-27. However, these external comments have resulted in changes to the label statements, and the PMRA has further revised the proposed label statements found in the PACR.

The PMRA has determined that brodifacoum, bromadiolone, chlorophacinone, diphacinone and warfarin are acceptable for continued registration. Mitigation measures to further protect workers, children, pets and the environment are specified in this RRD (Appendices II and III).

The registrants have been informed by letter of the specific requirements affecting their product registrations and the regulatory options available to comply with this decision. Further mitigation measures may be requested pending the finalization of the United States Environmental Protection Agency (USEPA) comparative ecological assessment and the results of the PMRA stakeholder consultation.
