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 directly affects foreign organizations and researchers who previously received NIH grants for animal research abroad, including projects funded under the $2.2 billion in grants from 2011-2021. The key provision amends the Public Health Service Act to ban NIH support for such overseas research, requiring all animal research funded by the NIH to occur within the U.S. (including territories and the District of Columbia). This change aims to address concerns about inadequate oversight of animal welfare in foreign labs where self-reported data may be inaccurate.
