The purpose of this legislation, known as the Worldwide Animal Testing Compliance and Harmonization Act of 2026 or the WATCH Act, is to enhance the oversight of foreign laboratories that conduct biomedical and behavioral research involving animals. The main objective is to ensure that these laboratories comply with U.S. animal welfare standards when they receive federal funding. Key provisions of the WATCH Act include the requirement for foreign laboratories to undergo quarterly inspections to verify their compliance with animal welfare regulations.
