Elanco Secures Emergency Authorization for Negasunt and Tanidil Against Screwworm Threats in Livestock

Elanco's Advancements in Livestock Health: Combatting New World Screwworm

In a significant move to safeguard livestock, Elanco Animal Health has recently unveiled its Emergency Use Authorization (EUA) for Negasunt™ Powder and Tanidil™. These products are poised to become instrumental in the prevention and treatment of New World screwworm infestations in livestock species. As confirmed cases of this detrimental pest edge closer to the U.S. border, Elanco's preparations are timely, reinforcing its commitment to livestock health innovations.

The Threat of New World Screwworm

New World screwworms (Cochliomyia homnivorax) are known for causing myiasis, a condition where larvae infest open wounds, leading to severe health complications. Confirmed sightings of these flies have been recorded just 62 miles from the U.S.-Mexico border, sparking concerns among veterinarians and livestock producers. This pest not only endangers the health of individual animals but can also trigger rapid infestations within herds if left unchecked. Recognizing the imminent threat, the federal agencies responsible for animal health—namely the FDA, EPA, and USDA—have acted swiftly to provide Elanco with the necessary authorizations for Negasunt and Tanidil.

Emergency Authorization Details

Elanco's Negasunt Powder, a combination of coumaphos, propoxur, and sulfanilamide, received its EUA for immediate use, while Tanidil, also composed of coumaphos and propoxur, is granted a Section 18 Emergency Exemption. Both products will be available exclusively through the U.S. Animal Plant Health Inspection Service (APHIS), coordinated with state-level animal health officials to ensure effective distribution.

Dr. Ellen de Brabander, Elanco's Executive Vice President of Research and Development, emphasizes the importance of these authorizations: “We appreciate our federal agencies' swift review of the scientific data demonstrating that these products may be effective in prevention and treatment against New World screwworm infestations.” The availability of these innovative solutions is crucial as livestock producers prepare for potential infestations.

Importance of Early Detection and Treatment

Effective early detection of open wounds on livestock is essential in preventing New World screwworm infestations. Elanco advocates for regular monitoring of livestock, encouraging producers to be vigilant and address any injuries promptly. Additionally, implementing a comprehensive fly and tick control regimen is paramount, as small bites can serve as entry points for the screwworm.

Dr. M. Wayne Ayers, an Elanco Sr. Technical Consultant, advises that self-education is key. Producers should familiarize themselves with credible resources concerning the New World screwworm, stay updated with treatment recommendations, and remain aware of active case locations. He states, “The second most important part of preventing losses from New World screwworm is for producers to keep their 'eyes on livestock.' Early intervention minimizes tissue damage and mortality risks.”

Preventing Wound-Causing Parasites

Preventing wound-causing parasites, such as ticks and biting flies, also plays a crucial role in combatting screwworm infestations. APHIS reports that controlling these pests helps reduce the likelihood of screwworms infesting livestock.

Elanco's portfolio includes various products effective in managing fly and tick populations on farms, available in formulations such as pour-on liquids, sprays, and dusts. Proactive measures in preventing injuries and infections can significantly curb the risk of a screwworm crisis.

Collaboration and Future Monitoring

In light of the evolving threat landscape, Elanco continues to collaborate with federal and state regulatory authorities to ensure that livestock producers and veterinarians are equipped with the tools and knowledge needed for effective management of New World screwworms. As the situation develops, regular updates and safety protocols will be made available by APHIS.

Producers are encouraged to stay informed through USDA and FDA resources regarding the New World screwworm and related control measures. The emergency use of both Negasunt and Tanidil signifies a proactive approach to ensuring livestock health and welfare during times of crisis.

For those involved in livestock care, it is critical to act swiftly and effectively in response to potential infestations, ensuring that the health of the animals—and the vital agricultural industry that relies on them—is safeguarded.

Elanco's 70 years of expertise in animal health continue to shine during these challenging times, reminding livestock producers that through education and innovation, they can overcome threats to their herds.
