The Sparc- open access to science July 15, 2014
This week sees the publication of the most comprehensive analysis to date of the nutritional composition of organic versus non-organic foods, and the accompanying levels of pesticide contamination. Published in the British Journal of Nutrition by UK scientists (Barański et al., 2014), the meta-analysis involved 343 peer-reviewed studies and found increased antioxidant levels in organic produce, many of which have been linked to reduced risk of chronic diseases. Pesticide levels were four times higher in non-organic produce and toxic metal levels were also significantly higher in non-organic foods.
The EU is set to increase the daily acceptable intake [of Glyphosate i.e. Round-Up] by 67 %, going against the independent science showing multiple pathways by which glyphosate causes serious harm to human health. The re-assessment, submitted to the European Safety Authority in January is fatally flawed by conflict of interest (Swanson and Ho, 2014). See Swanson (2014) for details on toxicology.
The US is on the verge of approving a new type of genetically modified crop, tolerant to the herbicide 2,4-D (as well as glyphosate). 2,4-D has already been associated with many illnesses including cancers, as summarised by Cummins (2012). A report by Centre for Food Safety has also summarised the issues surrounding this technology in Going Backwards: Dow’s 2,4-D-Resistant Crops and a More Toxic Future Exposure to 2,4-D.

Are US regulators dropping the ball when it comes to biocrops?
COLUMBIA, MISSOURI — Robert Kremer, a US government microbiologist who studies Midwestern farm soil, has spent two decades analyzing the rich dirt that yields billions of bushels of food each year and helps the US retain its title as breadbasket of the world.

Mr. Kremer’s lab is housed at the University of Missouri and is literally in the shadow of Monsanto Auditorium, named after the $11.8-billion-a-year agricultural giant Monsanto Co. Based in Creve Coeur, Missouri, the company has accumulated vast wealth and power creating chemicals and genetically altered seeds for farmers worldwide.
But recent findings by Mr. Kremer and other agricultural scientists are raising fresh concerns about Monsanto’s products and the Washington agencies that oversee them. The same seeds and chemicals spread across millions of acres of US farmland could be creating unforeseen problems in the plants and soil, this body of research shows.
Mr. Kremer, who works for the US Department of Agriculture’s (USDA) Agricultural Research Service (ARS), is among a group of scientists who are turning up potential problems with glyphosate, the key ingredient in Monsanto’s Roundup and the most widely used weed-killer in the world.
“This could be something quite big. We might be setting up a huge problem,” said Mr. Kremer, who expressed alarm that regulators were not paying enough attention to the potential risks from biotechnology on the farm, including his own research.
Concerns range from worries about how nontraditional genetic traits in crops could affect human and animal health to the spread of herbicide-resistant weeds.
