State officials and Iowa farm groups embraced the Trans-Pacific Partnership trade pact announced Monday.Although most details have yet to be disclosed, livestock industry officials say it will include substantial reductions in export tariffs for U.S. beef, pork, poultry and dairy products.The agreement “will reduce trade barriers” and “allow Iowa ag products to compete on a level playing field,” said Iowa Agriculture Secretary Bill Northey.“I think it will be good for Iowa,” said Dave Miller, director of research and commodity services for the Iowa Farm Bureau Federation.
