New World screwworm outbreak threatens Mexico-US border

Health and agricultural authorities are monitoring the spread of the New World screwworm (Cochliomyia hominivorax) across Mexico, raising concerns for the US-Mexico border. In Alpatláhuac, Veracruz, over 200 cases have been reported in animals, including livestock and pets. This infestation poses a significant threat to the livestock and agricultural sectors in Sonora and Baja California, with the potential to reach Arizona and California.

To mitigate the risk, authorities in both countries are implementing surveillance, inspecting animal movements, and utilizing sterile fly releases. The pest, which involves larvae feeding on the living tissue of warm-blooded animals, can cause severe infections or death if left untreated.

Separately, in Irapuato, Guanajuato, municipal authorities are responding to an independent academic evaluation of local security policies. Mayor Lorena Alfaro García announced commitments to integrate these findings into municipal strategy, focusing on reducing homicides and improving coordination regarding disappearances. Additionally, local civil protection officials reported that despite recent heavy rains, regional dams and rivers in Irapuato remain at safe levels and do not pose an immediate flood risk.
