USDA Reopens Southern Border for Livestock After Screwworm Threat

The USDA is set to reopen livestock importation from Mexico at select U.S. ports following a screwworm pest threat. Reopenings will begin on July 7 in Douglas, Arizona, with ongoing surveillance and sterile fly dispersion initiatives. Future ports in New Mexico and Texas will follow in phased timelines.

The U.S. Department of Agriculture announced on Monday a phased reopening of importation for cattle, bison, and equine from Mexico, after closing due to the New World screwworm pest.

Starting July 7, the entry port in Douglas, Arizona, will reopen as it is deemed the lowest risk entry point. The USDA cites a positive history of collaboration with Mexican officials in Sonora as a key factor. The closure began on May 11 due to the potentially devastating screwworm species, which has not been seen in the U.S. for decades. More ports in New Mexico and Texas may follow in subsequent weeks.

Efforts to combat the encroachment include opening a sterile fly facility in Texas and a $21 million investment in Mexico for fly production. USDA Secretary Brooke Rollins emphasizes the ongoing vigilance against the pest to protect American ranchers, detailing that conditions will be constantly evaluated after port reopenings.
