Other companies to voluntarily label GMO 's in their products

Just this week, national burrito chain Chipotle, which also supported Prop 37, realized like Whole Foods that it can act without being forced to do so by the government and began labeling all GMO ingredients.

This flood of voluntary information is not limited to the area GMO foods. Even as the FDA drags its heels on issuing regulations for restaurant menu labeling, big companies are filling that void thanks to consumer demand.

Panera Bread began posting calorie information in all its stores voluntarily more than three years ago. McDonald’s followed suit last year.

And this week, Starbucks announced it would start providing calorie information for all its products starting next week.
