A USDA study shows that a GM alfalfa has gone wild in alfalfa-growing parts of the West. This may explain GMO contamination incidents that have cost US growers and exporters millions of dollars - and it exposes the failure of USDA's 'coexistence' policy for GMOs and traditional crops.

The US Dept. of Agriculture (USDA) has long maintained that genetically engineered (GE) crops can co-exist with traditional and organic agriculture.

According to this 'co-existence' narrative, if neighboring GE and traditional farmers just sort things out among themselves and follow 'best management practices', transgenes will be confined to GE crops and the fields where they are planted.
