Bruce Tolentino, Deputy Director of the International Rice Research Institute, said his team has been perfecting their decades-old research on “Golden Rice”, which consists of genetically-modified rice grains infused with beta-carotene, a chemical substance responsible in producing Vitamin A in the body. He also said,“ In a Vitamin A-enriched rice, what the scientists did was to select three genes out of roughly 30,000 genes in a rice plant.

A study last month pointing to health risks from a type of genetically modified maize and a related pesticide did not provide grounds for questioning previous safety approvals, the French government said on Monday. The study by researchers at the University of Caen said rats fed on Monsanto's NK603 GM maize (corn) or exposed to the company's top-selling Roundup weed killer were at higher risk of suffering tumours, multiple organ damage and premature death. The government requested the opinion of health agency ANSES and biotechnology advisory council HCB, and in their conclusions released on Monday both bodies said the University of Caen study did not demonstrate the toxicity of the Monsanto products.
