CHICAGO, Feb 9 (Reuters) – The U.S. Department of Agriculture will open a facility in Texas by the end of next year that produces sterile flies intended to fight the flesh-eating parasite New World screwworm, Secretary Brooke Rollins said on Monday.
Rollins gave an update on the $750 million plant after announcing last August that USDA planned to build it in response to northward spread of the pest in Mexico toward the U.S. border.
Screwworms are parasitic flies whose females lay eggs in wounds on warm-blooded animals, often livestock. Once the eggs hatch, hundreds of screwworm larvae use their sharp mouths to burrow through living flesh, eventually killing their host if left untreated.
USDA produces 100 million sterile flies per week at a facility in Panama and disperses them in Mexico to prevent wild screwworm flies from reproducing.
The agency opened a dispersal facility for sterile flies in southern Texas on Monday, but experts have said USDA urgently needs to produce many more.
