Thousands of people marched in Taipei's streets on Sunday demanding the reversal of a decision to allow US pork imports into Taiwan, alleging food safety issues.

President Tsai Ing-wen's administration lifted a long-standing ban on US pork and beef imports in August. The ban is due to be lifted in January. That decision has met with fierce opposition, both by the opposition Kuomintang party and individual citizens. The new policy allows imports of pork with acceptable residues of ractopamine, a drug added into animal feed that promotes the growth of lean meat that some farmers use in pigs.
