What changed?
On October 2, 2025, HHS issued an official declaration granting FDA the ability to authorize the emergency use of animal drugs targeting infestations caused by NWS. Emergency Use Authorizations are typically reserved for urgent public health situations. In this case, these EUAs aim to address growing concerns about the NWS’s ability to spread and disrupt food production systems in the United States.
Why is the NWS a threat?
The New World Screwworm is a parasitic organism notorious for infesting warm-blooded animals, including livestock. These infestations result in severe wounds, secondary infections, and significant economic losses for farmers and food producers. The persistent risks posed by this screwworm species make rapid containment and treatment essential.
The reappearance of the NWS in regions of the United States has raised alarms among agricultural experts and policymakers. Without swift regulatory response, the parasite’s spread could threaten food supply chains and animal health across the country.
Regulatory implications
The emergency declaration aligns closely with FDA’s mission to protect public health and ensure the safety and security of the nation’s food supply. EUAs for animal drugs provide temporary permissions to deploy treatments that may not yet be fully approved but demonstrate reliable preliminary safety and efficacy data.
Animal drugs authorized under EUAs will still be subject to strict evaluations surrounding their intended purpose, performance, and safety. This process ensures that deployed measures adequately address infestation control without compromising animal welfare.
For regulatory, quality, and clinical teams, this announcement underscores the importance of proactive monitoring and preparation for emerging threats affecting animal and food safety.
FAQ
1. What is an EUA?
An Emergency Use Authorization allows the FDA to permit the use of medical products, including drugs, in response to public health emergencies. EUAs are temporary and based on available evidence demonstrating that benefits outweigh risks.
2. Which drugs are included?
HHS has authorized FDA to designate selected animal drugs targeting NWS infestations, subject to further evaluation and review.
3. How are affected stakeholders informed?
FDA typically engages with veterinary regulatory bodies, industry stakeholders, and clinical teams to communicate updates and guidance.
Conclusion
HHS’s timely declaration provides FDA a crucial regulatory tool to address the threat posed by the New World Screwworm. For clinical, quality, and regulatory professionals, this development highlights the importance of quick adaptability and collaboration during emergency situations.
