What's Happening?
Boehringer Ingelheim has been granted an Emergency Use Authorization (EUA) by the U.S. Food and Drug Administration (FDA) for its IVOMEC (ivermectin) 1% Injection. This authorization allows the use of the injection to prevent infestations caused by the New
World screwworm (NWS) in cattle. The NWS is a parasitic fly whose larvae can cause severe tissue damage and potentially fatal infestations in warm-blooded animals. Although the NWS is not currently present in the United States, recent cases have been reported in northern Mexico, particularly in Tamaulipas, a state bordering Texas. The EUA permits the use of IVOMEC for cattle within 24 hours of birth, during castration, or when a wound appears, except for female dairy cattle producing milk for human consumption and calves intended for veal. This is the first EUA for an over-the-counter drug aimed at preventing NWS infestations in cattle.
Why It's Important?
The authorization of IVOMEC as a preventive measure against the New World screwworm is crucial for the U.S. cattle industry. The NWS poses a significant threat to livestock health, which can impact the food supply and the economic stability of cattle producers. By providing a preventive tool, the FDA and Boehringer Ingelheim aim to protect cattle herds from potential outbreaks, especially given the proximity of recent cases in Mexico. This measure not only safeguards animal health but also supports the livelihoods of cattle producers by reducing the risk of labor-intensive management and potential economic losses associated with NWS infestations.
What's Next?
The EUA for IVOMEC will remain in effect as long as the circumstances justifying its emergency use persist, according to the Federal Food, Drug, and Cosmetic Act. Stakeholders, including veterinarians and cattle producers, are expected to collaborate closely with federal and state animal health officials to monitor and manage the risk of NWS. Continued vigilance and readiness are essential to prevent the spread of NWS into the United States, and further actions may be taken if the situation evolves.
