Gene Transfer
Another concern that has been raised by scientists is the cross pollination of plants and weeds that could produce a "super-weed" tolerant to herbicides. Cross pollination can also occur between non-GMO crops and GMO crops planted in close proximity of each other, according to ProQuest. The amount of GMO foods sold in the supermarkets today is minimal but they are making their way into processed foods such as fortified cereals and breads. These gene transfers are creating concern that they may have an unexpected and negative impact on the health of those who eat them. The GMO foods are designed for short-term benefits to the production of plants, but the long-term hazards have not been evaluated.
