The U.S. Department of Agriculture has enacted an immediate suspension of live animal imports via the southern border, citing concerns over the New World Screwworm, a flesh-eating parasite. This decision includes halting imports of cattle, horses, and bison from Mexico to protect the U.S. livestock industry from potential outbreaks. Mexican authorities have criticized the suspension as unfair, arguing that the threat does not justify the restrictions placed on beef imports. As concerns about the screwworm escalate, ranchers on both sides of the border are worried about the economic impact and are calling for measures to combat this devastating pest.
