In the first GMO labeling initiative since California voters rejected Prop 37 last November, voters once again rejected the mandatory labeling scheme.  The vote, which will likely end up being about 54% opposed and 46% in favor when certified, appears to have been heavily influenced by late campaigning from opponents.  Opponents spent about $22 million against the initiative while proponents spent about $8 million, although estimates are that only about 6% of the total amount spent came from in-state sources.

The defeat is a significant blow to proponents of mandatory GMO labeling who, with the exception of legislation passed in Connecticut that is largely contingent upon other states adopting similar laws before it is implemented, have had significant difficulty convincing voters and legislatures to adopt such initiatives. Trade groups, such as the Grocery Manufacturers Association, are looking to shift the conversation towards a “federal solution that will protect consumers by ensuring that the FDA, America’s leading food safety authority, sets national standards for the safety and labeling of products made with GMO ingredients.”
