OPPOSITION Agriculture Minister Mick Murray has called for the implementation of emergency spillage procedures for genetically modified seed and grain spills after a Williams farmer reported GM canola plants growing on the side of Albany Highway after a truck spill in August. Mr Murray said to minimise the threat of contamination, clean-up procedures for GM needed to be handled with more stringent protocols and not treated the same as non-GM seed spills. He said strict quarantine and long-term monitoring after clean-ups was needed to ensure GM seed spills were handled better in WA.
