The Environment and Animal Society of Taiwan (EAST) yesterday said it suspected that the Council of Agriculture had concealed cases of avian influenza for more than two years and had lied to the World Organisation for Animal Health (OIE) in its reports.

The group said former premier Wu Den-yih (吳敦義) and former Council of Agriculture minister Chen Wu-hsiung (陳武雄) should be held responsible for the cover up.
