As of Wednesday afternoon, only one animal was confirmed to have screwworm. Dr. Burke Healey with USDA’s Animal and Plant Health Inspection Service said this case was in southern Mexico. The United States shut down its border and is working closely with Mexican animal health officials. “Mexico has put in a robust system. They’ve got multiple checkpoints that protect their southern border that they utilize to find this particular case so we’re confident in their system and we working hand in hand with them to come up with a protocol to reestablish trade.”
