Chicago cattle futures fell on Monday after the USDA reported a human case of New World screwworm in the U.S.
The case, investigated by the Maryland Department of Health and the U.S. Centers for Disease Control and Prevention, was confirmed by the CDC as New World screwworm on August 4, and involved a patient who returned from travel to El Salvador, HHS spokesman Andrew G. Nixon told Reuters.
No animal cases have been confirmed in the U.S. this year. The U.S. closed its border to Mexican cattle imports in July due to a case of New World Screwworm.
