On September 30 2025, U.S. for the very first time conditionally approved Dectomax-CA1 injectable (Doramectin) to prevent and treat against the terrifying Screwworm in cattle. This comes in handy after massive reflection concern over the parasite creeping north from Mexico. It allows cattle producers to use the drug immediately while further studies are conducted, signaling a necessary, rapid deployment against an imminent threat
For African livestock producers, this rapid U.S. response is a vital lesson. As we’ve discussed previously in our post “The risk of Screwworm Spread in Africa: Lessons from the US and Implications for Africa” biosecurity lapses have global consequences. Even if Dectomax-CA1 isn’t available locally, the principle remains: early detection, regulated movement control, and rapid response are the pillars of protection.
Ultimately, innovation and new drugs like Dectomax-CA1 are crucial, but they only work when paired with strong, consistent biosecurity protocols and strict stewardship. Whether in Africa or the Americas, eradicating this devastating parasite can only be achieved through relentless vigilance and preparedness.
