However, the Trump administration and livestock ranchers anticipate infestations that could reduce the nation's cattle herd and lift beef prices, already at record highs. The best method to fight screwworm is by breeding sterile flies that reduce the mating population of wild flies. Cattle ranchers may need quick access to screwworm drugs in the meantime, and there are no FDA-approved drugs for screwworm in the US. This could allow veterinarians and ranchers to access products more quickly, rather than waiting for a longer FDA review process. Colonius said the FDA was assessing literature reviews of products that were approved for other uses to determine what may be effective against screwworm.
