From OLAW:
On March 22, 2013, the NIH published a Federal Register Notice on Implementation of the Updated American Veterinary Medical Association (AVMA) Guidelines for the Euthanasia of Animals (FR Doc# 2013-06661 – PDF). This Notice provides guidance to Public Health Service awardee institutions on implementation of the 2013 Edition of the Guidelines (PDF). The NIH is seeking input from the public on any concerns they may have regarding the updated Guidelines. Public comments must be submitted electronically on or before May 31, 2013: Submit comments.
The AVMA has issued and posted an update to the 2007 Guidelines on Euthanasia with a new title, AVMA Guidelines for the Euthanasia of Animals: 2013 Edition available at https://www.avma.org/KB/Policies/Documents/euthanasia.pdf (PDF). OLAW encourages PHS-Assured institutions to begin using the 2013 Guidelines when reviewing research projects as soon as possible, and expects full implementation after September 1, 2013. Previously approved projects undergoing continuing review according to PHS Policy, IV.C.5., which requires a complete de novo review at least once every 3 years, must be reviewed using the 2013 Guidelines after September 1, 2013.
