CARGO Act of 2025

The CARGO Act of 2025 prohibits the National Institutes of Health (NIH) from funding any research involving live animals conducted outside the United States. It amends the Public Health Service Act to ban NIH grants, contracts, or other support for such research, affecting foreign organizations currently receiving NIH funding for animal studies. The bill directly impacts NIH grantees operating internationally, requiring all animal research funded by the U.S. government to occur within U.S. borders, including states and territories. This policy change aims to address concerns about inadequate oversight of animal welfare in foreign labs, where NIH previously provided about $2.2 billion for such research from 2011-2021.
