Mexico's Secretaria de Economia has determined that the existing duties on bone-in and boneless cuts of beef produced and exported from the U.S. would remain in effect for an additional five years -- through April 28, 2010.

Beef has been subject to antidumping duties from Mexico since 1999, even though a North American Free Trade Agreement (NAFTA) dispute settlement panel ruled, in 2004, that Mexico improperly imposed the antidumping duties. -- P. Scott Shearer, Washington, D.C., correspondent and Stephanie Veldman
