"This report is fundamentally flawed and unscientific; key recommendations are not based on sound science and are contradicted by the report's own scientific findings," the Environmental Protection Agency and the U.S. Trade Representative said in a joint statement. "Implementing many of the report's recommendations would cause economic harm to farmers and consumers of all NAFTA countries and restrict international trade."
The U.S. statement specifically criticized one recommendation -- that all U.S. corn coming into Mexico be milled at or near the border so it cannot be planted. That practice, it says, "would increase the cost of U.S. corn significantly, negatively affecting Mexico's livestock producers and consumers."
The NAFTA report and the U.S. response are also far apart on what constitutes a scientific assessment of the issue. The report included information about the attitudes of Mexican farmers to the genetically modified corn, saying many find it frightening and a threat to their staple food, while American officials said those views have no place in a scientific study.
In support of their formal critique, the U.S. agencies cited the report's conclusion that "scientific investigations and analyses over the past 25 years have shown that the process of transferring a gene from one organism to another does not pose any intrinsic threat over the short or long term, either to health, biodiversity or the environment."
The NAFTA report went on, however, to conclude that the specific characteristics of any newly created organism need to be examined -- making the case that the benefits and dangers of any genetically modified plant can be determined only by testing in the locales where it will be used. In the United States, the EPA, the Agriculture Department and sometimes the Food and Drug Administration must approve genetically modified plants before they can be introduced.
The National Corn Growers Association also sharply criticized the panel's conclusions. "The report needlessly raises concerns where there are none about a technology that is proven safe and already greatly benefits the environment and farmers around the world," NCGA President Leon Corzine said.
A copy of the NAFTA report was leaked last month to the environmental group Greenpeace, which distributed it in Mexico. The report was released Monday.
After the initial release, Mexico's equivalent of the EPA, Semarnat, said in a statement: "There is no doubt that the recommendations in the official document will be beneficial for Mexico and its environment. . . . Semarnat is awaiting the official publication of this report and is confident that the majority of the recommendations made will be implemented."
