Proposed Rule
Summary
The USDA is asking for your thoughts on updating rules that keep animal medicines safe and effective. These rules affect farmers, vets, and businesses making or selling vaccines and treatments for animals (not people). They want to modernize these rules by October 13, 2026, to keep up with new science and technology without raising costs.
Analyzed Economic Effects
5 provisions identified: 4 benefits, 0 costs, 1 mixed.
USDA plans broad regulatory modernization
USDA is asking for public input to modernize the rules in 9 CFR parts 101-118 and 123-124 that implement the Virus-Serum-Toxin Act (VSTA). The agency says it may update these rules to encourage innovation, protect animal health, and improve regulatory clarity while staying true to the VSTA; comments are due by October 13, 2026.
Possible streamlining of licensing and approvals
USDA asks how processes such as licensing, production updates, facility approvals, inspections, or reporting could be streamlined in parts 101-118 and 123-124 to reduce administrative burden while preserving product quality, availability, and effectiveness. The agency specifically solicits examples of costs incurred when complying with current requirements.
Alignment with international standards considered
USDA asks how 9 CFR parts 101-118 and 123-124 could better align with international standards to support or preserve global market access, reduce duplicative requirements, and improve harmonization. The agency asks commenters to say how changes could impact domestic manufacturers' ability to export to other markets.
Potential flexibility for emerging technologies
USDA asks for input on how to incorporate greater regulatory flexibility into parts 101-118 and 123-124 to accommodate emerging technologies, novel product categories, or evolving production systems without compromising safety or effectiveness. The request explicitly mentions accommodating new R&D, manufacturing, and distribution practices.
Modernization could change technical compliance rules
The regulations being reviewed currently include rules on facility design and operation, equipment sanitation, production controls, testing and serial release, packaging and labeling, recordkeeping, animal management, inspection authorities, and detention or disposition of non-compliant products. USDA's RFI signals these technical requirements are candidates for modification as part of modernization.
