“The United States’[s] suspension of live cattle imports from Mexico hit at the worst possible time for rancher Martín Ibarra Vargas, who after two years of severe drought had hoped to put his family on better footing selling his calves across the northern border. Like his father and grandfather before him, Ibarra Vargas has raised cattle on the parched soil of Sonora, the state in northwestern Mexico that shares a long border with the United States, particularly Arizona. His family has faced punishing droughts before but has never before had to contend with the economic hit of a new scourge: the New World Screwworm, a flesh-eating parasite. U.S. agriculture officials halted live cattle crossing the border in July – the third suspension of the past eight months — due to concerns about the flesh-eating maggot which has been found in southern Mexico and is creeping north.” (08/05/25)
