"Euthanasia is the act of killing animals by methods that induce rapid unconsciousness and death without pain or distress. Unless a deviation is justified for scientific or medical reasons, methods should be consistent with the 2000 Report of the AVMA Panel on Euthanasia (AVMA 2000 or later editions). In evaluating the appropriateness of methods, some of the criteria that should be considered are ability to induce loss of consciousness and death with no or only momentary pain, distress, or anxiety; reliability; nonreversibility; time required to induce unconsciousness; species and age limitations; compatibility with research objectives; and safety of and emotional effect on personnel." - The Guide
The IACUC does not take the euthanization of animals lightly. Every animal at CSULB is accorded equal consideration including animals of lower orders not afforded protection under the Animal Welfare Act Regulations.
