USDA banned cattle from the Mexican state of Durango into the U.S. in early June, citing inadequacies in its bovine TB management program. The Animal and Plant Health Inspection Service learned animals from the section of Durango not allowed to export cattle into the U.S. were being moved into the section of Durango from which export to the U.S. is allowed.

Durango is Mexico's third-largest cattle exporting state, with its cattle making up 16.5% of all cattle imported into the U.S.

Last year, nearly 1.4 million head of cattle — mostly light feeder steers and heifers — were imported to the U.S. from Mexico. Through March of this year 335, 687 head had been imported, a 9.4% increase over the same period a year ago.
