Tyson said in a statement it was not aware of any improprieties in U.S. chicken exports to Mexico, adding that exports of chicken from its U.S. plants to Mexico amounted to less than 1 percent of its $1.9 billion in international chicken sales in fiscal 2010.
Mexican imports of U.S. chicken surged 18 percent in the first 11 months of 2010 to 876.53 million pounds to displace Russia as the biggest buyer of U.S. chicken, according to the U.S. Department of Agriculture.
