Existing Product Receives Conditional Approval for New World Screwworm

Zoetis Inc. announced Tuesday, Sept. 30, that Dectomax®-CA1 Injectable is the first and only parasite control product to receive conditional approval from the U.S. Food and Drug Administration for the prevention and treatment of infestations caused by the larvae of Cochliomyia hominivorax (myiasis), and prevention of reinfestation for 21 days. This conditional approval applies to beef cattle, female dairy cattle less than 20 months of age, pregnant beef cows, newborn calves and bulls.

In a news release announcing the approval, Zoetis stated it is committed to supporting livestock producers with scientific solutions for this economically devastating pest. New World screwworm (NWS) poses a continuing threat to livestock health, and the financial ramifications of the disease to the U.S. ag economy are estimated in the billions of dollars.1

“New World screwworm has the potential to bring unprecedented economic and animal health harm to livestock producers,” said Mike Lormore, director of cattle and pork technical services at Zoetis. “Our top priority is to support keeping animals healthy and provide timely, efficacious solutions to our customers and partners. With this conditional approval, Dectomax-CA1 Injectable can now be used as part of safe, effective control measures against New World screwworm.”

Zoetis has long supported a One Health approach to emerging and transboundary infectious diseases and has a strong track record of quickly developing innovative solutions to provide customers with the right mix of tools for prevention and treatment strategies.

Livestock producers are encouraged to work closely with their herd veterinarian to implement strategic prevention and control measures.
