The federal government has imposed a quarantine zone around a St. Catharines, Ont., farm where a strain of bird flu was discovered. "All premises located within this zone will be placed under quarantine; however, only the initial infected premises has confirmed positive for avian influenza. The CFIA says the avian control zone is part of an "internationally accepted practice" so trade can continue in areas of the country that aren't infected.
