Pesticide Testing to Help Verify Organic Foods
American Chemical Society’s Journal of Agricultural and Food Chemistry published a report on a new strategy to determine organic authenticity. Researchers developed a method to analyze the metabolites generated within plants when pesticides break down. The test can determine that organic produce has been fraudulently treated with pesticides, even if the pesticides themselves have degraded. The test can also reveal accidental contamination of organic produce. It can also identify pesticide treatment of organic grapes by testing wine made from those grapes. The researchers say that their methodology, with some refinement, should aid in food regulators’ efforts to crack down on illegal practices in organic farming.
