Yet the Agriculture Department reported that recent tests identified the strain after an Oregon farmer trying to clear a field sprayed Monsanto’s herbicide, Roundup, and found that the wheat could not be killed.
The report rattled U.S. wheat markets. In addition to Japan’s action, the European Union, which imports more than 1 million tons of U.S. wheat a year, said that it was following developments “to ensure E.U. zero-
tolerance policy is implemented.” It asked Monsanto to help detection efforts in Europe.
The developments focused attention on St. Louis-based Monsanto, a $56 billion company with more than $13.5 billion in sales of seeds, services, weed killer and biotechnology to the agriculture industry. In the face of mounting protests, including a series of public demonstrations in multiple cities last weekend, the company has stood behind its other genetically modified products.
Many food safety advocates and environmental groups say that more testing needs to be done to ensure that genetically modified seeds don’t harm human health. In addition, they say, the genetic engineering of crops has encouraged the more widespread use of herbicides and led to the development of weeds more resistant to those herbicides.
The United States already relies heavily on genetically modified crops. Genetically engineered corn, cotton and soybeans have gone from 5 to 17 percent of the U.S. market in 1997 to between two-thirds and more than 90 percent in 2012. By some estimates, more than 70 percent of processed foods sold in the United States contain ingredients and oils from genetically engineered crops.
A 2008 Government Accountability Office report estimated the value of the global market for genetically engineered seeds was $6.9 billion. Though altered seeds are made by four other leading agricultural businesses, Monsanto relies most heavily on such products, experts said.
But Americans remain skeptical about some genetically modified foods, including current proposals to cultivate altered salmon. And big agriculture companies have avoided commercial development of genetically engineered wheat because about half of the U.S. wheat crop is exported, and governments in major markets such as the European Union, Japan and China are opposed to genetically modified wheat seed.
Monsanto said in a statement that it ended commercial development of the strain of wheat found in Oregon nine years ago. The company said that about 58 million acres of wheat is planted in the United States every year, and that while the Agriculture Department’s test results in Oregon “are unexpected, there is considerable reason to believe that the presence of the Roundup Ready [herbicide-resistant] trait in wheat, if determined to be valid, is very limited.”
But food safety groups drew the opposite conclusion. “This was not from a recent trial, which means it’s been sitting there in the environment,” said Andrew Kimbrell, executive director of the Center for Food Safety, a nonprofit group. “It’s highly doubtful that it’s just on one farm. If it’s out there, it’s out there.” The center’s science policy analyst, Bill Freese, added, “It’s been 12 years since this wheat was grown officially in Oregon. It doesn’t just disappear and magically appear 12 years later.”
Freese added that Monsanto has 15 new permits, issued in 2011, to test herbicide-resistant wheat in Hawaii and North Dakota, including an unusually large 300-acre field in North Dakota. Freese said the size of that field would make it difficult to prevent accidental spread.
Tom Helscher, a Monsanto spokesman, said the new field tests involve “different herbicide traits” than the genetically modified strain found in Oregon. He said they are “focused on preventing yield loss due to disease and other environmental stressors.” He said the company has a project in early development that would boost yields and provide crops with a “strong tolerance” to existing herbicides.
Helscher said that “we talk to people in the wheat industry and they say they need tools to help deal with problems they face, whether weed or insect control.” He added, “We wouldn’t expect to have a product for quite a number of years,” but that Monsanto thought the research was “worthwhile.”
In its statement, Monsanto said it would help the Agriculture Department “get to the bottom of the reported genetically modified wheat detection,” but it insisted that “there are no food, feed or environmental safety concerns associated with the presence of the Roundup Ready gene if it is found to be present in wheat.”
Part of the battle over genetically modified seed has been taking place in Washington.
Monsanto and other companies in the industry have been pressing members of Congress to vote against measures that would require disclosure for food made with genetically modified or engineered crops. Friends of the Earth, an environmental group, says that 64 countries have similar rules and that, this year, 37 bills have been introduced in 21 states proposing that genetically engineered foods be labeled in stores.
Monsanto is also urging lawmakers to vote for a rider in the Senate continuing resolution that would strip federal courts of the power to provide injunctive relief to environmental and food activists seeking to stop the spread of such crops.
Genetically modified crops have a history of provoking bans by trading partners. In 2006, the Agriculture Department announced that trace amounts of a regulated variety of genetically engineered rice had been commingled with supplies of conventional rice. That led several U.S. trading partners to refuse U.S. rice exports, causing losses for U.S. farmers and exporters.
The 2008 GAO report described six “unauthorized releases” of genetically engineered crops into the U.S. feed and food supplies over the previous eight years.
