Animal Welfare Standards and International Collaborations.

Globalization of the biomedical research enterprise is occurring at an accelerating pace. Increasingly, scientific collaborations and contracts cross national borders. Assurance that the caliber of animal research and animal welfare are consistent among countries and that such animal use is done in a humane and conscientious manner is of significant concern to the scientific community, the general public, and other stakeholders. Bridging these international collaborations is a clear scientific imperative for statistical validity of the data and reproducibility of results to ensure the animal use is both meaningful and impactful. One way to mitigate the potential confounding effects that the welfare of the animals may have on the research data is to harmonize animal care and use practices and procedures worldwide. By harmonizing the care and use of animals, using high standards that are internationally accepted, research animal welfare and high-quality science will be achieved.
