A new weapon in the fight against a destructive cattle parasite has gained regulatory approval, offering hope to livestock producers across the United States. Merck Animal Health announced in December that it secured conditional approval for Exzolt Cattle-CA1, a topical treatment designed to combat New World screwworm infestations.
The fluralaner-based solution is applied directly to cattle as a pour-on treatment and serves a dual purpose – it can both ward off potential infestations and eliminate existing screwworm larvae problems. This parasite remains a persistent worry for American cattle ranchers and poses broader risks to the nation’s agricultural sector.
New World screwworm larvae create serious health issues for livestock by feeding on living tissue, making effective prevention and treatment methods crucial for maintaining healthy cattle herds and protecting agricultural investments.
