Animal Use in Research:
Federal Agencies Should Assess and Report on Their Efforts to Develop and Promote Alternatives
GAO-19-629: Published: Sep 24, 2019. Publicly Released: Sep 24, 2019.
Researchers often use animals to study disease, test product safety, experiment, or teach. Some uses cause animals pain or distress. Federal agencies require researchers to consider alternatives to animal use, such as computer modeling or working with cell cultures.
The Department of Health and Human Services and other agencies have developed animal use alternatives and collaborate on these efforts in an interagency group. However, the agencies don’t routinely measure the effect of those efforts. We recommended that HHS create a workgroup to help agencies assess and report on their progress in reducing or replacing animal use in research.

What GAO Found
The Department of Health and Human Services (HHS), U.S. Department of Agriculture (USDA), and Environmental Protection Agency (EPA) use a variety of methods to ensure researchers consider alternatives to animal use in research (see figure). Two of these methods are (1) requiring researchers to obtain approval of their research protocols, including their consideration of alternatives, from their institutions, and (2) calling for or recommending researchers to use database searches to identify alternatives. HHS and USDA also help ensure that researchers consider alternatives through the agencies' oversight of research facilities. For example, USDA is to conduct annual inspections of nonfederal research facilities. Futhermore, the agencies have provided training to researchers on the consideration of alternatives.
HHS, USDA, and EPA have facilitated the development and use of alternatives to animal use in research through individual and collaborative efforts. These efforts include agency strategies and policies for promoting the use of alternative methods and the development of testing methods that rely on non-animal models. Additionally, the agencies are members of the Interagency Coordinating Committee on the Validation of Alternative Methods, which is managed by HHS's National Institute of Environmental Health Sciences. The committee promotes testing methods that protect human health and the environment while reducing animal use. The interagency committee's 2018 strategic roadmap calls for it to identify appropriate metrics for monitoring progress and measuring success in adopting alternatives. However, the committee and its member agencies have not routinely developed or reported metrics that demonstrate how their efforts to encourage the use of alternative methods affect animal use. They have also not designated an interagency workgroup to address the challenges related to developing and reporting such metrics. Facilitating the establishment of such a workgroup would help the committee and its member agencies better monitor their progress across the range of their efforts to reduce animal use and report members' progress to the public.

Why GAO Did This Study
U.S. research facilities use a wide range of animal species in research, and some procedures used during such research cause animals pain or distress. Federal laws and principles require that researchers consider alternatives to animal use, such as in vitro methods and computer modeling. HHS, USDA, and EPA conduct and fund animal research and regulate products tested on animals. HHS and USDA also oversee federal and nonfederal research facilities including researchers' consideration of alternatives to animal use.
GAO was asked to review issues related to alternatives to animal research. This report (1) describes how HHS, USDA, and EPA ensure researchers consider the use of alternatives to animals and (2) examines the steps the agencies have taken to facilitate the use of alternative research methods and to assess the effect of their efforts on animal use. GAO reviewed documents, such as agency policies and practices relevant to the consideration of alternatives and interviewed agency officials. GAO also interviewed representatives of a nongeneralizable sample of 12 federal and nonfederal research facilities randomly selected across agencies and facilities.
What GAO Recommends
GAO recommends that HHS's National Institute of Environmental Health Sciences facilitate the establishment of an interagency workgroup to develop metrics for assessing progress on the development and promotion of alternatives to animal use and incorporate those metrics into public reports. HHS agreed with our recommendation.

Recommendation for Executive Action
Comments: The National Institutes of Health concurred with our recommendation. In its September 3, 2019, letter commenting on our draft report, the agency stated that the National Institute of Environmental Health Sciences was reviewing the recommendation and would provide an action plan for its implementation. We will continue to monitor the agency's actions to determine whether it has implemented our recommendation.
Recommendation: The Director of the NIH's National Institute of Environmental Health Sciences should (1) facilitate the establishment or designation of a workgroup of representatives of the Interagency Coordinating Committee on the Validation of Alternative Methods member agencies to develop metrics that the agencies could use to assess the progress they have individually or collectively made toward reducing, refining, or replacing animal use in testing and (2) incorporate those metrics into the committee's biennial progress reports.
