It's official: The struggle over labeling genetically modified food is now the most expensive ballot-measure fight in Oregon history.



Two campaigns for and against Measure 92 have now reported raising a combined $17.2 million. The "yes" campaign has collected $6.1 million, while the opposition has hauled in $11.1 million.



That shatters the previous record, $16.2 million spent on a failed 2007 measure to raise tobacco taxes.



The latest contributions, reported late Friday, were actually made Oct. 10—so even more money has likely arrived, with three weeks left until election day.



Measure 92 would require a four-word label on foods containing genetically engineered organisms. Health activists see the labels as letting consumers choose whether to consume GMOs, but food producers see labeling as a potential scarlet letter for their products.



The donations reported this weekend fit that pattern. The "no" campaign received $468,000 from Coca-Cola, $230,000 from Mexican bread giant Bimbo Bakeries, and $380,000 from margarine manufacturer Land O'Lakes.



The "yes" side received a $500,000 donation from Tom Hormel of Fort Lauderdale, Florida. Property records indicate Hormel is heir to the fortune of the canned-meat company that created Spam.
