Australia’s largest frozen lamb exporter has joined calls for state bans on genetically modified crops to be extended. South Australia, Victoria and New South Wales are all reviewing their moratoria on commercial GM crops, and are under pressure from farm groups and the Federal government to lift the restrictions. Food processor Goodman Fielder has called for the bans to stay, and has been backed by South Australia’s Tatiara Meat Company, which wants the GM bans to continue for another five years.
