USDA Deregulates GM Alfalfa

http://blog.wholefoodsmarket.com/2011/01/urgent-action-needed-to-support-organics-and-non-ge-crops/

The USDA is considering only two options:

1) fully deregulate GM alfalfa OR
2) conditionally deregulate it by placing certain rules and restrictions on growing GM alfalfa that would minimize or limit contamination of non-GM crops (including organic).

Far as I can tell from what available online, the only advantage of growing the GM alfalfa is that one can eliminate all non-GM plant life on the field by spraying the herbicide Roundup.  According to Gurain-Sherman* using Roundup does not increase yields significantly, even over the short term. In the long run, weeds will become resistant to Roundup, either through naturally occurring mutations or through borrowing the Roundup Ready gene from GM crops. Herbicide resistance has already become a large problem in some locations (http://huerto-de-altamira.blogspot.com/2010/09/herbicide-resistant-pigweed-jobs-for.html)

Dangers of Consuming Genetically Modified Organisms

Excerpt:

There is more than a casual association between GM foods and adverse health effects. There is causation as defined by Hill's Criteria in the areas of strength of association, consistency, specificity, biological gradient, and biological plausibility.⁵ The strength of association and consistency between GM foods and disease is confirmed in several animal studies.^{2,6,7,8,9,10,11} 

Specificity of the association of GM foods and specific disease processes is also supported. Multiple animal studies show significant immune dysregulation, including upregulation of cytokines associated with asthma, allergy, and inflammation. ^6,11 Animal studies also show altered structure and function of the liver, including altered lipid and carbohydrate metabolism as well as cellular changes that could lead to accelerated aging and possibly lead to the accumulation of reactive oxygen species (ROS). ^7,8,10 Changes in the kidney, pancreas and spleen have also been documented. ^6,8,10 A recent 2008 study links GM corn with infertility, showing a significant decrease in offspring over time and significantly lower litter weight in mice fed GM corn.⁸ This study also found that over 400 genes were found to be expressed differently in the mice fed GM corn. These are genes known to control protein synthesis and modification, cell signaling, cholesterol synthesis, and insulin regulation. Studies also show intestinal damage in animals fed GM foods, including proliferative cell growth9 and disruption of the intestinal immune system.⁶ 

Regarding biological gradient, one study, done by Kroghsbo, et al., has shown that rats fed transgenic Bt rice trended to a dose related response for Bt specific IgA. ¹¹ 

Also, because of the mounting data, it is biologically plausible for Genetically Modified Foods to cause adverse health effects in humans. 

In spite of this risk, the biotechnology industry claims that GM foods can feed the world through production of higher crop yields. However, a recent report by the Union of Concerned Scientists reviewed 12 academic studies and indicates otherwise: "The several thousand field trials over the last 20 years for genes aimed at increasing operational or intrinsic yield (of crops) indicate a significant undertaking. Yet none of these field trials have resulted in increased yield in commercialized major food/feed crops, with the exception of Bt corn."¹²However, it was further stated that this increase is largely due to traditional breeding improvements. 

Therefore, because GM foods pose a serious health risk in the areas of toxicology, allergy and immune function, reproductive health, and metabolic, physiologic and genetic health and are without benefit, the AAEM believes that it is imperative to adopt the precautionary principle, which is one of the main regulatory tools of the European Union environmental and health policy and serves as a foundation for several international agreements.¹³ The most commonly used definition is from the 1992 Rio Declaration that states: "In order to protect the environment, the precautionary approach shall be widely applied by States according to their capabilities. Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation."¹³ 

Why to Boycott GM Food Products

Leaving health issues aside, because there is not enough evidence one way or the other -- the reason anyone who values his or her life should refuse to buy GM foods is that the courts in the U.S. and Canada have interpreted the patent laws in such a way as to make it impossible for anyone, even home gardeners, to save their own seeds for any crops that can cross pollinate with plants whose DNA contains patented genes.

The videos in my two previous posts illustrate the law in action.

Modified Genes Spread to Local Maize (Mexico)

http://www.kysq.org/456149a.pdf

NATURE|Vol 456|13 November 2008

Transgenes from genetically modified (GM) maize (corn) crops have been found in traditional
‘landrace’ maize in the Mexican heartland, a study says. The work largely confirms a similar, controversial result published in Nature in 2001 (ref. 1) and may re-ignite the
debate in Mexico over GM crops. The paper reports finding transgenes in three of the 23 locations that were sampled in 2001, and again in two of those locations using samples taken in 2004. Written by a team led by Elena Álvarez-Buylla of the National Autonomous University of Mexico (UNAM) in Mexico City, the study will be published in the journal Molecular Ecology.

[...]

However, the new paper doesn’t confirm an important conclusion from the original Nature paper — whether the transgenes had been integrated into landrace genomes and passed along to progeny plants. Álvarez- Buylla suspects this may be the case, but she’s not interested in pursuing another round of politically charged battles — and will leave that work to others.
