USDA Secretary Announces Agreement with Mexico on Beef Parasite

Secretary of Agriculture Brooke Rollins announced Monday that Mexico had come to an agreement with the U.S. for handling the New World screwworm. Over the weekend, the USDA secretary threatened to halt beef imports from Mexico if the country did not take more steps to respond to the spread of the New World Screwworm. This screwworm is a deadly parasite that spreads by burrowing into the living flesh of an animal. This parasite has spread to humans in rare cases.

In her letter to her Mexican counterpart, Secretary Rollins wrote, “If these issues are not resolved by Wednesday, April 30, USDA will restrict the importation of animal commodities, which consist of live cattle, bison, and equine originating from or transiting Mexico to protect the interest of the agriculture industry in the United States.”

“Every delay in granting full operational authority and eliminating customs barriers undermines our collective ability to carry out this emergency response,” the USDA secretary added.
