SPOKANE, Wash. -

Record amounts of cash have been raised on both sides of Initiative 522, the measure to make Washington the first state in the nation to require foods with genetically engineered ingredients marked on the label. But who is filling each side's war chest?

Initiative 522 would require some products like chips, soft drinks and candy to be labeled if it contains genetically engineered ingredients like peanuts.

If you've turned on the TV lately, you've seen the ads for the initiative, which supporters say that consumers have a right to know if the foods they buy contain genetically engineered ingredients. Opponents, however, say 522 will cost farmers and food processors and raise food prices.

Campaign finance records show the majority of money in this race is coming from out of state.

The No on I-522 has raised a record $21 million. Top contributors include biochemical companies including Monsanto, Bayer CropScience and DuPont. The Grocery Manufacturers Association pitched in $3.8 million against 522 with contributions from companies like Pepsi, Nestle and Coca Cola.

Meanwhile supporters of the Yes on I-522 effort have raised $6.8 million for the initiative. Major donors include an organic soap company from California and the Center for Food Safety in Washington DC.

What 522 could cost the consumer is really at the center of the debate, as both sides have studies supporting their point. The pro-522 side says labeling didn't raise food prices in Europe while the anti-labeling side says it will because food producers will have to reformulate products with more expensive non-GMO ingredients to avoid the new labeling.

The Seattle Times says polls have the race at a toss-up right now.
