The conventional blocks of oranges were treated with up to nine herbicides and four insecticides. Weeds were controlled in the organic trees with cultivation, and insects were controlled with neem oil and pheromone traps. Interestingly, the team reported few differences between the conventional and organic oranges at the time of picking, although the organic fruit was marginally smaller and contained 13% more Vitamin C.

Hernandina, Journal of the Science of Food and Agriculture, 2008 Organic Management Stabilizes Soil Carbon and Quality Scientists in New Zealand studied soil carbon dynamics and soil quality in a conventional integrated apple orchard in New Zealand, compared to a nearby organic apple orchard. The integrated system utilized Integrated Pest Management practices, including the application of synthetic pesticides. They found that conventional management reduces soil carbon in the top 0.3 meter of soil in the tree row, while organic management limited C losses to 0.1 meter and improved soil physical properties and the diversity of soil microbial populations. The research team concluded that soil C management was sustainable in the organic system but not in the integrated system. Source: M.

A paper in the April 2008 issue of Molecular Nutrition and Food Research reports that grape juice was more effective than fresh grapes in preventing atherosclerosis in a study involving hamsters fed a high-fat diet. Widely reported research done at the University of Wisconsin-Madison concluded that far smaller doses of resveratrol than previously thought can help promote heart health. Resveratrol is a key antioxidant in red grapes and wine that is thought to explain part of the health benefits of the Mediterranean diet. Previously, research suggested that a person would need to consume 100 bottles of red wine to receive enough resveratrol to improve heart health, but the new study confirmed beneficial effects in rats at a human dose level equivalent to about four glasses of red wine per day. These new findings are expected to accelerate the effort underway in the food industry to produce resveratrol-supplemented foods. Already, several resveratrol dietary supplements are on the market. Editors Note: Before you rush out and start popping resveratrol pills, remember that all beneficial antioxidants, including resveratrol, become pro-oxidants at high doses, and that in setting safe daily doses, it is important to take into account all other dietary or medicinal sources of antioxidants. Companies marketing resveratrol pills or other antioxidant-based dietary supplements bear an obligation to educate consumers on this important point. If any readers of The Scoop know of data helpful in establishing the safe range for resveratrol intakes, please pass it along to The Scoop cbenbrook@organic-center.org. Government Report Highlights Major Changes Ahead in the Wake of Climate Change The U.S. Climate Change Science Program has put out a major report entitled The Effects of Climate Change on Agriculture, Land Resources, Water Resources, and Biodiversity in the United States. The time horizon covered in the report is the recent past to 2030 to 2050, although some longer-term impacts are considered. The authors conclude that Ecosystems are likely to be pushed increasingly into altered states with the possible breakdown of traditional species relationships The report describes a long list of adverse impacts of climate change, and acknowledges that science cannot project how quickly, or how serious the impacts will prove to be, in part because of uncertainty in earths adaptive capacities. In the chapter on agriculture, the authors foresee greater climate-driven variability in crop yields. Research suggests that there will be a northern migration in weed species, and that the number one herbicide in the U.S., glyphosate (Roundup), will not work as well because of elevated CO2 levels and the spread of resistant weeds. Disease pressure on many agronomic crops will worsen, while late season forage production will increase in northern areas. Production on livestock farms will be adversely impacted in hot regions as a result of added stress, in the absence of greater attention by farmers and investment in structures designed to keep animals cool. Heat waves, and droughts, will become more intense, more frequent, and longer lasting. Access the 342 page report here.

The link between specific pesticides and diabetes was strong in the case of seven pesticides, out of a total of 50 specific active ingredients studied. The organophosphate insecticide trichlorfon, mostly used on golf courses, increased the risk of diabetes by 2.5 fold. All seven of the pesticides found to cause the greatest increase in diabetes risk are chlorinated compounds, providing the researchers an important clue for future research. A number of golfing organizations and publications have reported these findings, citing other studies that have reported increased risk of diabetes among people who play golf. Source: M.P.

Beneficial Bacteria Help Suppress E. coli O157 Scientists working for the USDAs Agricultural Research Service have shown that beneficial bacteria can out-compete some harmful pathogens, and in the process, suppress the buildup of pathogens, including E. coli O157. This is one of the primary reasons why the promotion of microbial biodiversity on organic farms can reduce food safety risks. In some cases the pathogen-suppression caused by colonization with beneficial bacteria is linked to a competitive effect the beneficial bacteria use up energy sources or moisture needed by the pathogen. In other cases, the beneficial bacteria produce chemicals that act like antibiotics in suppressing pathogens. In the absence of competitive bacteria or other control agents, pathogen populations can grow 100,000-fold higher in a day or two when moisture and temperature conditions are favorable.

The U.S. seized the moment to promote genetically engineered seeds, while arguing that American biofuels policy accounted for a very small around 3% -- share of the blame for rising commodity prices. That claim, and the Economic Research Service analysis upon which it is based, did not pass the laugh test at the summit. The International Monetary Fund projects that biofuels account for 30% of recent price increases. at last weeks United Nations food summit, the worlds more-developed nations proved, once again, that domestic politics trumps both humanitarian concerns and sound strategic calculations.

Source: Andrew Pollack, Monsanto Seeks Big Increase in Crop Yields, New York Times, June 5, 2008 Editors Note: The agricultural biotechnology industry has made many promises over the years that it has been unable to deliver on. For the most part, people take the industrys rosy scenario predictions with a grain of salt. After all, unbridled optimism, even if misplaced, never hurt anyone, right? Wrong. The hype over agricultural biotechnology has played an important role in triggering and sustaining a mammoth shift in the focus of public and private food and agricultural research. The share of research dollars and people trained in molecular genetics and the tools of genetic engineering have gone up dramatically, at the expense of nearly every other scientific discipline and approach to the study and enhancement of farming systems. The uncritical acceptance of biotech industry hype on Wall Street reshaped and concentrated the global seed industry, shifting power, freedom of choice, and money away from farmers and to a few multinational corporations. We have placed a dangerously large share of our collective agricultural science eggs in the GE basket and in the decades ahead, the world will reap the consequences. Given the effectiveness of industry spin and the lack of independent assessment of the impacts of todays GE technologies, it is doubtful that we will ever really understand the full range of these consequences. Biotech hype thrives in todays vacuum of information and insight on the real impacts of Monsanto-style genetic engineering, and erodes the foundation from which consensus might emerge for a new direction in pursuit of food security for all. Buying Local has Modest Impact on Total Food System Greenhouse Gas Emissions A study published in Environmental Science and Technology concludes that the production of food accounts for 83% of food system greenhouse gas emissions (GHG), while the delivery of food to consumers accounts for just 4%. The study concludes that food choices have a far greater impact on GHGs than buying all food locally. In particular, acording to the study, GHG emissions can be dramatically reduced by shifting away from beef and dairy products to fish, chicken or vegetables. Source: Rachel Ehrenberg, For foods ecological impact, meat means more than miles, Science News, May 24, 2008 Editors Note: Like most studies of this type, the authors of the EST study had to make a variety of assumptions in the course of producing their estimates. One of the important assumptions is that all beef and dairy animals are fed grain-based diets in a feedlot setting where pasture plays little or no role in meeting the animals nutritional needs. The GHG emissions of a grass-based beef or dairy operation are profoundly different than from farms that depend mostly on grain, concentrates, and harvested forages. A farm that relies on grazing saves significant energy because
Moreover, well managed, grazing-based operations sequester substantial quantities of carbon in the soil, while preventing the losses of nitrous oxide triggered by the production and application of nitrogen fertilizers on land growing corn. The advantages of grass-fed beef production and dairy farms are bound to grow more compelling in this era of high-priced grain and oil. Big Grant Supports Research on Organic Dairy Production The University of New Hampshire has received a $380,000, three-year grant from USDAs Sustainable Agricultural Research and Education (SARE) program to conduct a study on organic dairy farms as a closed ecosystem. The focus of the project will be on innovative ways to close nutrient and energy cycles on small New England dairy farms. Methane digesters will be explored as one way to meet on farm energy needs. Preliminary research at the university suggests that the goals of a largely closed organic dairy ecosystem, self-sufficient in terms of energy and crop nutrients, may indeed be feasible.

Doyle worries about the ability of food imports to carry pathogens from one continent to another, especially in cases where food is shipped from a place where people and animals have developed a degree of immunity to a pathogen, to places where the pathogen has never or rarely occurs.

Dangerous Strain of MRSA Bacteria Infects People for the First Time Three patients in Great Britain have become infected with the ST398 strain of MRSA (Methicillin-resistant Staphylococcus aureus), a dangerous bacterium previously found only on hog farms in the Netherlands, Denmark, Belgium, and Germany. A survey by Dutch authorities in 2006 found the strain in 20% of pork products, 21% of chicken samples, and 3% of beef. This strain of MRSA is resistant to a different set of antibiotics, and if not detected quickly, can lead to inappropriate treatment prescriptions. Experts suspect that the bacteria infected these individuals after eating undercooked, or handling contaminated meat products.

California Senate Ag Committee Passes GMO Legislation Designed to Protect Farmers Assembly Bill 541 protects farmers from patent infringement lawsuits when GE-pollen or seeds unknowingly blow or find their way onto a farmers land. It also requires companies to get written permission from farmers before taking crop samples of their land to test for the presence of GE-traits. Legislators hope to amend the bill to also address additional liability issues and concerns that are unique to organic farmers. A surprisingly broad coalition supports passage of the bill, including sustainable agriculture, environmental, and consumer groups, the California Farm Bureau, and the California Cotton Ginners and Growers Association.

Creekstone Case Could Undermine Ability to Prove the Benefits of Organic Livestock Products By: Dr. Charles Benbrook Creekstone Farms Premium Beef is a small specialty beef producer selling premium Angus products to grocery chains, restaurants, and customers in Europe, Latin America, and Asia. In 2006, Creekstone started to use a Bovine Spongiform Encephalopathy (BSE) rapid test kit to screen slaughter cattle for the presence of BSE at its plant in Arkansas City, Kansas. The company had been told by several overseas customers that such screening would be necessary to continue shipments of product, especially cuts from cattle under 30 months of age. The company started a testing program, but was blocked by an order from the USDA . Litigation ensued, which has been working its way through the courts over the last two years. The case was argued in May, 2008 before the U.S. Court of Appeals for the District of Columbia, and a decision is expected within weeks. The USDAs only real argument against the use of the BSE test kit by Creekstone is that if Creekstone were to deploy the test kit for this purpose, all other beef manufacturers would be forced to follow suit, and this would increase production costs and reduce the competiveness of the U.S. beef industry. If the USDA prevails in this argument, it could become very difficult, if not unlawful, for the organic livestock industry to carry out testing programs designed to assure consumers that organic meat, dairy, and poultry products are safe and of high nutritional quality. Given the need to improve the nutritional quality and safety of all kinds of foods, both in the U.S. and worldwide, it is hard to imagine why the USDA is working so hard to block a private company from using a proven test methodology in response to requests from overseas customers. An increase in public and private sector testing for pesticides, bacteria, mycotoxins, animal diseases, and adulteration seems like a logical response given evidence that the globalization of the food supply is increasing old, and creating new food safety challenges. But the USDA seems inclined to block or mute attempts to differentiate food based on methods of production, use of biotechnology, nutritional quality and food safety. This policy threatens to undermine the long-term ability of farmers and food companies to enhance food quality and safety through innovative production systems and products that meet legitimate consumer demands.
