If food companies choose voluntarily to label their products as genetically modified, fine. But the power of the law has no business here. But this is not the case. Unaltered foods are no safer. They may even be less safe than GM foods.
Unmodified foods contain endogenous pesticides, toxins, and allergens.
No one can guarantee that GM foods are perfectly safe. The same can be said for unmodified foods. Some anti-GM activists claim that GM foods are not tested. Either way, the claims are false. The FDA thoroughly tests these foods, including soybeans genetically altered to resist Monsanto's well-known Roundup herbicide.
