The response was prompted by a Greenpeace article saying that the environmental protection group had discovered a study backed by the U.S. Department of Agriculture involving feeding genetically modified Golden Rice to a group of 24 children, aged between six and eight, in Hunan.
The study, published in the August edition of The American Journal of Clinical Nutrition, claimed that Golden Rice, genetically engineered to be rich in carotene, is effective at providing vitamin A to children.
A spokesman for Hengyang City, where the study was allegedly conducted, said the government has formed an investigation team to probe the claim, but initial findings indicated that there had been no such research project.
The spokesman said there was instead a study on the transformation of carotene in vegetables to vitamin A in children's bodies. The study, commissioned to its Hunan branch by the Chinese Center for Disease Control and Prevention (CDC) in 2008, selected 68 primary school children in Hengyang's Hengnan County for the experiment.
"The food given to the children did not involve GM rice or other GM food," the spokesman said. "Parents were notified of the experiment in advance."
Hunan CDC officials said that the food for the experiment was all locally purchased and all results were submitted to the China CDC immediately after the experiment concluded.
The government spokesman said the CDC study had not involved any American institute.
GM food is controversial as there is still no consensus on whether or not it is harmful for the human body. The State Council of China introduced a regulation as early as 2001 to ensure the safety of genetically modified food, with strict provisions on its research, testing, production and marketing.
