Thousands of livestock farmers march the street to protest against Taiwan government's plan to allow beef imports from the United States in Taipei March 8, 2012. Taiwan government plans to lift a ban on most U.S. beef containing ractopamine, a drug that is used as a feed additive to promote leanness in pigs and cattle, according to local media. The protesters are against lifting the ractopamine ban for any kind of meat. The placards read, "no mad cow disease." "No ractopamine." REUTERS/Pichi Chuang (TAIWAN - Tags: FOOD POLITICS CIVIL UNREST)
