The New FundingThe $25 million will go toward building a sterile fly dispersal facility in Douglas, the second such site in the country after an existing facility in southern Texas. The agency identified Sonora and Chihuahua as the lowest-risk Mexican states for screwworm, citing their strong animal inspection programs and geographic distance from southern Mexico, where most cases have been concentrated. Every animal entering the US through reopened ports will undergo a full USDA inspection for signs of the parasite. The Outbreak by the NumbersMexico has recorded more than 34,000 New World screwworm cases since the outbreak began, including two in Chihuahua, one of the two states USDA considers lowest-risk. Whether the Santa Teresa and Columbus ports follow will depend on the outcome of the initial reopening and continued monitoring of screwworm risk in Sonora and Chihuahua.
