Illegal GE rice contaminates food chain in China

Press release - 2005-04-13
Greenpeace is calling for an urgent, international product recall after uncovering the illegal release of a variety of genetically engineered (GE) rice in China. The GE rice has not been approved for human consumption and may have contaminated Chinese rice exports.

"The GE industry is out of control," said Greenpeace GE campaigner Sze  Pang Cheung. "A small group of rogue scientists have taken the world's  most important staple food crop into their own hands and are subjecting  the Chinese public to a totally unacceptable experiment."

"We're calling on the Chinese Government to take urgent action to recall  the unapproved GE rice from the fields and from the food chain, and to  conduct an immediate inquiry into the source of the contamination."

A Greenpeace research team discovered unapproved GE rice being sold and grown illegally in the Chinese province of Hubei. Interviews with seed  providers and farmers indicate that GE rice seeds have been sold over  the past two years. Samples of rice seed, unmilled and milled rice have  been collected from seed companies, farmers and rice millers. Testing by  the international laboratory Genescan has confirmed the presence of GE  DNA in X samples.

The evidence from the lab, combined with field reports, confirms that  the illegal GE variety is Bt Rice - which is genetically engineered to  produce an inbuilt pesticide. Greenpeace estimates at least X tons of GE  rice has contaminated the rice market.

According to Greenpeace International Scientific Advisor, Dr Janet  Cotter, this is a very serious problem requiring urgent Government  action: "There are strong warning signs that this GE Bt rice could cause  allergenic reactions in humans. It has been shown that the protein  produced in Bt rice (called Cry1Ac) may have induced allergenic-type  responses in mice (1). To date, there has been no human food safety  testing of Bt rice."

China is a major exporter of rice and it is expected that the  contamination scandal may have significant trade and market impacts,  particularly in countries like Japan and Korea where consumer rejection  of GE foods is very high. A similar case in the USA in 2001 resulted in  a $1 billion product recall amid concerns of potential allergenic  reactions after GE corn (Starlink) illegally entered the human food  chain.

"This will have a major impact on the Chinese as well as international  rice markets," said Sze. "China is one of the world's major rice  exporters and our customers in Japan, Korea, Russia and Europe are  strongly opposed to GE foods."

Consumer concern over GE foods in China is also rising. In an opinion  poll released by Greenpeace in March, a majority (57%) of the  respondents said they would choose non-GE food over GE food, a big leap  from 40% in 2004. The poll showed that Chinese consumers were even more  cautious when faced with GE rice. According to the survey, seventy-three  percent of the respondents said they would choose non-GE rice.

China is considering commercialization of GE rice and officials have  indicated a decision may be made this year. The contamination scandal  raises the question of whether the government could regulate GE rice.  "The government has not controlled GE rice in the research stage, how  will it regulate large scale commercialization?" Sze said.
