Greens MP says farmers in the Williams area are likely to have no legal recourse if their crops were contaminated by GM canola from yesterday’s spill, unless they can prove negligence on the part of the freight carrier. [...] Janette Liddelow, whose farm is near the spill and grows non-GM canola for sale to Japan, said she was concerned about losing her contracts if any GM contamination occurred. She has called for the moratorium on GM crops to be reinstated.
