Proposition 37 is simple. It would require a label on foods sold in California which are genetically engineered or contain engineered ingredients. Just like existing nutrition, ingredient, and allergen labels, a Proposition 37 label would provide relevant information to consumers about the food they might buy.
It's hard to imagine a rational argument against providing consumers with additional information about the products they buy. And opponents of Proposition 37 haven't provided one.
The opponents are mainly big pesticide and junk food companies who are worried that their products might not sell as well if consumers knew what they were eating. But they don't want to admit that their only concern is their own profits, so they're spending millions to try to confuse voters instead. That's why the opposition's advertising campaign doesn't actually argue against labeling per se; incredibly, its main argument is that Proposition 37 has too many exemptions!
Voters should know that many of the exemptions opponents highlight are the same ones that already apply to practically every other food label. Others are included to avoid duplication of existing laws or to make the law more enforceable. The fact that opponents have chosen to bombard us with ads about these arcane legal issues, rather than talking about labeling itself, shows that they have lots of cash but no good arguments.
If you think you have the right to know what's in your food, ignore all the misleading ads and vote yes on Proposition 37.
