In the November 2012 elections, voters of Washington state had to decide on Initiative 522. I-522 would require food sold in the state to be labeled if any of its components were produced by genetically modified organisms (GMOs).
Proponents made a necessary distinction between selectively bred plants and animals and those that are GMOs. Selective breeding has been standard practice in agriculture since man began herding animals and growing crops. GMO plants and animals are those that have a genetic makeup that would not occur naturally through normal breeding. For example, a plant that has had a gene inserted that gives it resistance to weed killer and a cow that has been cloned so it is immune to mad-cow disease are GMOs.
It was a contentious battle, with supporters of I-522 telling consumers that genetic engineering has unintended consequences and that ingesting GMO products may make us sick. Proponents insisted that we have a right to know what is in our food.
