Racehorse Health and Safety Act of 2025

Repeals the federal Horseracing Integrity and Safety Act of 2020 and replaces federal oversight with a framework that lets States form an interstate compact and creates a national Racehorse Health and Safety Organization (RHSO) to set and enforce uniform medication-control and racetrack safety rules. The bill establishes advisory committees (breed-specific medication committees and a Racetrack Safety Committee), enforcement and testing protocols, preemption of conflicting State law, and penalties for rule violations.

Most of the new regulatory structure and rules do not take full effect immediately: many provisions become operative either two years after enactment or when at least two States join the compact (whichever is later), with some shorter interim timelines and limited immediate-effect provisions for definitions and compact consent.
