Monsanto’s Glyphosate in Californian Wines

After the news of beer in Germany testing positive for glyphosate, now comes word that various wines have been analyzed and proved positive for glyphosate contamination. Microbe Inotech Lab of St.Louis found 10 different wines, from large and small vineyards, contained glyphosate, including wine made with organic grapes.
The contamination of conventional wine was 28 times higher than organic wine, with levels ranging from 0.659 ppb in organic to 18.74 ppb in conventional wine.
The wines tested came from Napa Valley, Sonoma and Mendocino counties in California. The brand names of the wines were not revealed.
Roundup/glyphosate is sprayed every year in conventional vineyards. A 12 ft strip is sprayed on either side of the grape vines which are planted in rows, to kill weeds when the plants are dormant in late winter or early spring. This results in a 24 foot strip of Roundup sprayed soil with grapevines in the middle.
According to Dr. Don Huber at a talk given at the Acres USA farm conference in December of 2011, the vine stems are inevitably sprayed in this process and the Roundup is likely absorbed through the roots and bark of the vines from where it is translocated into the leaves and grapes.
Roundup/glyphosate cannot be used in organic vineyards so the presence of glyphosate/Roundup in the two wines using organic and biodynamic grapes is obviously unexpected. Since the majority of vineyards in these three counties use Roundup and spray at the same time, it is suspected that airborne drift from nearby vineyards contaminated the organic and biodynamic crops.
