The New World screwworm is advancing northward from Panama to Mexico, raising significant concerns among officials in nine countries. This fly's larvae feed on living flesh, severely affecting livestock and even humans, with numerous infections reported this year. Efforts to control its population include the release of sterile male flies to disrupt reproduction, a technique that previously eradicated the screwworm from the U.S. However, the pest's recent breach of containment in Panama poses new challenges, risking further spread throughout Central America.
Officials across nine countries are urgently combating the New World screwworm's rapid spread, which threatens livestock and human health across Central America.
The threat of the New World screwworm comes as ranchers face devastating losses from this pest, which feeds on the living flesh of their cattle.
