The Sustainability Council is calling for New Zealand to regain control of its food safety regulation, by renegotiating a trans-Tasman agreement on food standards. The council says the national regulator, the Food Safety Authority (NZFSA), last year shopped for a more palatable assessment of the safety of a genetically-engineered maize after it received an unfavourable evaluation from state science company, Environmental Science and Research (ESR). ”New Zealand can, in theory, go its own way and decline approval for a particular new food,” said the council’s executive director, Simon Terry.
