Ilagan learned that widely publicized studies purporting to show ill health effects from eating genetically modified foods have been discounted. He found that there is little risk of genetically modified genes cross-pollinating with plants of other species, although the risk is never zero. He learned more about "superweeds" that resist herbicides designed to kill them. They likely arise from extensive herbicide use with Monsanto's Roundup Ready crops, not directly from the Roundup Ready genes themselves. They're a problem, but not necessarily one that has to come with GMO foods.
