Methods of euthanasia deemed "acceptable with conditions" may require scientific justification before IACUC approval.

The statement that methods of euthanasia deemed "acceptable with conditions" may require scientific justification before IACUC approval is rooted in the ethical principles guiding animal research. The IACUC, or Institutional Animal Care and Use Committee, is responsible for ensuring that all aspects of animal research adhere to humane practices and are justified scientifically.

When a method of euthanasia is classified as "acceptable with conditions," it indicates that while the method may be recognized generally, it has specific circumstances or limitations under which it can be used. To ensure these methods are appropriate and justified, researchers must provide a scientific rationale for their use, outlining how it aligns with humane treatment principles and ensuring that it is consistent with the goals of the research.

This requirement helps uphold ethical standards in animal research and ensures that decisions regarding euthanasia methods are not only scientifically valid but also consider the welfare of the animals involved. Such scrutiny is critical in maintaining the integrity of research practices and addressing public and regulatory concerns regarding animal welfare.
