Ag Secretary Brooke Rollins announced risk-based port re-openings for cattle, bison, and equines from Mexico beginning as early as July 7. USDA - after extensive collaboration between the Animal and Plant Health Inspection Service experts and their counterparts in Mexico to increase New World screwworm surveillance, detection, and eradication efforts - is set to begin a phased reopening of the southern ports, starting with Douglas, Arizona. Progress has been made in several critical areas since the ports were closed on May 11, including the resolution of challenges with conducting flights in Mexico that allowed the USDA team to consistently conduct sterile NWS fly dispersal seven days a week and the dispersal of more than 100 million flies each week. “We’ve focused on fighting the New World screwworm’s advancement in Mexico,” Rollins said. “We have made good progress with our counterparts in Mexico to increase surveillance efforts and have boosted sterile fly dispersal efforts.”
