The aim of these CPD webinars (Continuing professional development) is to follow the legal requirements for maintenance and demonstration of competence in laboratory animal science, and to facilitate the implementations of the 3R’s in routine animal work.

Euthanasia means a ‘good death’. Most laboratory rodents are killed with carbon dioxide (CO2), a procedure which is often referred to as euthanasia. This talk will summarize extensive evidence that CO2 negatively impacts animal welfare when used to end the life of rats and mice.

Evidence shows that CO2, even in low concentrations causes fear or anxiety which cannot be avoided if it used to kill rodents. Therefore, CO2 cannot be considered a method which offers a ‘good death’ for these species, and, moreover, that it should be considered a harm and factored into harm-benefit analyses when it is used to kill experimental subjects.

Current and potential practical alternative methods are compared to consider whether any of these offer the potential of a good death.
