Study says Roundup Ready corn causes health problems in rats; some scientists question research

A long-term diet of herbicide-resistant corn caused tumors, organ damage and premature death in rats, according to French researchers who have conducted the first animal feeding test to determine effects of eating genetically modified food over a lifetime, Clive Cookson of The Financial Times reports. The study focused on the most widely planted herbicide-resistant corn, Monsanto's Roundup Ready.

The study, which was published in the peer-reviewed journal Food and Chemical Toxicology, divided 200 rats into groups of 10. Some were fed Roundup Ready corn, some Roundup-laced drinking water and some Roundup Ready corn that had been sprayed with Roundup. Researchers concluded that not only is eating GM corn harmful, but Roundup itself causes health effects even at concentrations below the legal limit for residues in water supplies.

Other scientists have criticized the study's methodology, saying tumor-prone rats were used, there were too few control groups of rats, and the study was also led by Gilles-Eric Seralini, a critic of genetically modified food. (Read more)

'Pink slime' maker suing ABC News for defamation

The beef company most affected by the "pink slime" controversy earlier this year is taking legal action against ABC and its news division for defamation of character. Beef Products Inc. claims the news organization cost the company $400 million. Anchor Diane Sawyer and reporters Jim Avila and David Kerley are also named as defendants.

“ABC ran for about 30 days a vicious disinformation campaign that consists of almost 200 false and misleading defamatory statements,” BPI attorney Dan Webb told Tim Carman of The Washington Post. The South Dakota-based company is asking for $1.2 billion because the state's Agricultural Food Products Disparagement Act allows plaintiffs to triple the amount of damages. ABC News senior vice president Jeffrey Schneider said the lawsuit "is without merit," and that the organization will "contest it vigorously."

Several media outlets reported on lean, finely textured beef, that was once widely used in fast-food burgers, school lunch programs and sold in grocery stores. But reporters discovered a reference to LFTB as "pink slime" in 2002 by former U.S. Department of Agriculture microbiologist Gerald Zirnstein, and it was revealed that ammonia was combined with meat during the process of making LFTB.

Beef Products is singling out ABC because it says that since March 7 the network reported about LFTB in 11 broadcasts, 14 online reports and in social-media statements that allegedly contained 200 false statements about the product. But media libel defense lawyer Laura Handman told Schneider that Beef Products could have a difficult time winning the suit because it will be hard to determine whether ABC knew what it reported was false.

Researcher says nanomaterials could have 'profound' negative effect on food crops

Nanomaterials, which are created by manipulating matter on an atomic and molecular scale, may be harming the quality and yield of food crops, University of California researchers concluded in a report released in the online edition of Proceedings of the National Academy of Sciences.

The materials are being used in many consumer products,which  including shampoos, gels, hair dyes and sunscreens, which are washed into the environment. Researcher John Priester told Bobbie Mixon of the National Science Foundation that as their uses increase, the likelihood of nanomaterials contaminating food crops rises. "Conventionally treated wastewater is a primary source of normally nutrient-rich organic materials applied to agricultural soil, and farmers beneficially use this treated water and the biosolids from it as fertilizer," Mixon reports. "As nanomaterials become more prevalent, there is concern about nanomaterials buildup in soils and possible nanomaterials entry into the food supply."

There had been no previous study of the affects of nanomaterials on a soil-based crop, so researchers grew soybeans, a major global commodity, in soil containing high amounts of nanomaterials. They found that two nanomaterials -- cerium oxide powder and zinc oxide -- "could profoundly alter soil-based food crop quality and yield," Mixon reports. (Read more)

House plan to cut GMO crop oversight rings alarms

"An array of consumer and environmental organizations and individuals are ringing alarm bells over moves they say will eradicate badly needed safety checks on crops genetically modified to withstand herbicides, pests and pesticides," Charles Abbott and Carey Gilliam of Reuters report. "The measures could speed the path to market for big biotech companies like Monsanto and Dow Chemical that make billions of dollars from genetically altered corn, soybeans, cotton and other crops."

"They are trying to change the rules," Center for Food Safety lawyer George Kimbrell, who has lawsuits pending against government regulators for failing to follow the law in approving certain biotech crops, told the wire service. "It is to the detriment of good governance, farmers and to the environment."

Abbott and Gilliam note that the House could take up a measure that would allow biotech crops to be planted even if courts rule they were approved illegally. That could happen as early as next week. Opponents call it the "Monsanto Rider" because Monsanto's genetically altered alfalfa and sugar beets have been subject to court challenges for illegal regulatory approvals.

Last week 40 food businesses, retailers, family farmers and others sent a protest letter to House Agriculture Committee leaders "calling on them to strike pro-biotech provisions added to the draft of the Farm Bill," Reuters notes. "The measures followed several court rulings that regulators did not follow legal requirements in approving some biotech crops, and would nullify just such legal requirements in the future. Environmental hazards associated with biotech crops, including the rapid rise of 'superweeds' that cannot be killed with traditional herbicides, would not have to be taken under consideration by regulators in new approvals, the critics say."
