The US will reopen its border to Mexican cattle in phases from August 24 after a screwworm outbreak, lifting shares of meatpackers Tyson Foods and JBS.

The US will resume Mexico cattle imports on August 24 at Douglas, Arizona, ending a roughly 15-month suspension over the New World screwworm.

USDA closed multiple ports last year in an effort to slow the spread of the screwworm, which could devastate the ranching industry in Texas.
