Sec. Rollins shuts down livestock trade at U.S. southern border ports due to NWS case in Mexico

Agriculture Secretary Brooke Rollins has closed all ports of entry at the southern border, just days after a phased reopening. It comes as USDA learned of a fresh detection of New World Screwworm in Mexico.

Mexico’s animal safety team confirmed the pest was discovered in a small municipality in Veracruz, which is about 160 miles north of a sterile fly facility and about 400 miles south of the U.S. border.

As a result, Secretary Rollins says all future planned reopenings at the U.S. border are on pause. On Monday, a port of entry reopened in Arizona. In a statement, Rollins said she is closing livestock trade at all southern ports of entry, effective immediately. She wants to see more progress on Mexico’s part in battling New World Screwworm.

The National Cattlemen’s Beef Association is happy with the decision but wants further action at home. CEO Colin Woodall says the Screwworm’s travel north jeopardizes the safety of American agriculture. He is calling for an expedited opening of a sterile fly facility here in the U.S., saying we cannot wait any longer, and he is urging USDA to begin plans as soon as possible. In June, Secretary Rollins announced groundbreaking of that facility at Moore Air Base in south Texas.
