The Federal Animal Research Accountability Act of 2025 would amend the Public Health Service Act to require entities conducting biomedical and behavioral research with NIH funds to report annually the total number of animals bred, housed, and used, with a species-by-species breakdown and a categorization by pain or distress and the use of anesthesia or analgesia. The reporting would cover activities in teaching, research, experiments, or tests and would distinguish between procedures with no pain and those that involve pain or distress.
It also requires the NIH Director to provide a standardized form to animal care committees and to post the collected data publicly in an online database within three months after filing. The amendments take effect two years after enactment.
Taken together, the bill aims to close data gaps, improve oversight, and foster accountability in federally funded animal research, while imposing new administrative obligations on institutions and NIH.
At a Glance
What It Does
Adds a new subparagraph to Section 495(b) requiring an annual form to tally animals bred, housed, and used, with species counts and four pain/distress categories. It also obligates NIH to provide the form to animal care committees and to post the data publicly online within three months after filing.
Who It Affects
NIH-funded research entities (universities, medical centers, contract research organizations) and their animal care committees; the NIH as data steward and public database operator.
Why It Matters
Enhances transparency and data accuracy for animal use in federally funded research, supporting oversight, reproducibility, and public accountability.

What This Bill Actually Does
The bill would update the Public Health Service Act to require NIH-funded entities to report annual, species-level counts of animals bred, housed, and used in teaching and research, with explicit segmentation by whether procedures involved no pain, pain/distress with analgesia, or pain/distress without analgesia, as well as animals bred or held not yet used. A standardized form would be provided to animal care committees, and NIH would publish the resulting data in a public, searchable online database within three months after filing.
The amendments would apply two years after enactment. The goal is a clearer, more complete picture of how animals are used in federally funded research and to enable greater oversight and accountability, while imposing new reporting duties on institutions and NIH.
The Five Things You Need to Know
The bill requires an annual, species-by-species animal-use count with pain/distress categorization.
The form must include totals for animals bred, housed, and used, plus four defined subcategories.
NIH must supply the reporting form to animal care committees and publish data publicly online within 3 months after filing.
The amendments apply two years after enactment.
The measure targets NIH-funded biomedical and behavioral research conducted by diverse entities.

Reporting requirements and public data access
Amends Section 495(b) to add subparagraph (D), requiring an annual form that tallies animals bred, housed, and used, by species, and broken out into four categories related to pain or distress and the use of analgesics or anesthesia. The Director of NIH must provide this form to animal care committees, and not later than three months after filing, make the form publicly available online in a searchable database.
Delayed applicability
The amendments take effect two years after the date of enactment, providing a transition period for institutions to implement new reporting and data-sharing requirements.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- NIH-funded universities, medical centers, and contract research organizations benefit from a standardized reporting framework and clearer accountability.
- Animal care committees gain access to uniform data collection tools to monitor compliance and welfare practices.
- The public and policymakers gain transparent access to animal-use data, supporting oversight and informed discussions about animal research practices.
- Ethical review bodies and animal-welfare advocates acquire clearer data to evaluate welfare standards and compliance.
- Funders and policymakers obtain a data-driven basis for evaluating efficiency and welfare outcomes in funded research.
Who Bears the Cost
- Research entities must implement data collection, verification, and reporting processes, incurring personnel and IT costs.
- Institutions may need to upgrade animal-management and data systems to capture required counts and categories.
- NIH will bear ongoing costs to maintain and secure the public database and support the data pipeline.
- Smaller or under-resourced entities may face higher relative burdens in meeting new reporting obligations.
Key Issues
The Core Tension
Transparency versus administrative burden: the bill seeks richer, public data on animal use but must balance the accuracy, consistency, and administrative costs of collecting, validating, and publishing those data.
The bill raises important questions about data accuracy, interpretation, and administrative burden. Defining “pain” and “distress” can be subjective across institutions and species, potentially requiring additional guidance to ensure consistent categorization.
Releasing detailed animal-use data publicly could raise concerns about reputational risk for research entities and may require safeguards against misinterpretation of raw counts. The 3-month posting window imposes a tight timeline for data processing, validation, and quality control, while the two-year delay provides needed breathing room but pushes a longer horizon before full transparency takes effect.
