A TRUCK carrying genetically modified canola has crashed in the WA Great Southern region in a spill the Australian Greens have described as a ‘’serious biohazard’’.

The accident happened near the intersection of South Coast Highway and Cheyne Road about 50km east of Albany and about 465km southeast of Perth.

A WA Police spokesman said the last trailer of a road train overturned and there were no injuries.

The Greens say they have “serious concerns over potential GM contamination’’.

``Spills of this sort need to be treated as a serious biohazard, given the threat that widespread GM contamination could occur’’ Senator Rachel Siewert, Australian Greens agriculture spokeswoman, said.

``Non-GM farmers face huge financial losses if their crops are contaminated.

``A release of this nature could also seriously threaten our natural environment. In situations when GM crops are spilt, there needs to be a priority placed on containment, clean-up and monitoring.’’

The party has called for the reinstatement of a moratorium on GM crops in WA and changes to the laws governing liability and food labelling in order to protect the choices of farmers and consumers across the state.
