A recount for Measure 92, which would require GMO labeling on food products in Oregon, will begin this week.

The measure was defeated by just 812 votes out of more than 1.5 million cast, according to the final results certified last week.

A full recount is required if the difference between the votes cast for and against a measure is not more than one-fifth of one percent of the total votes cast, according to the Secretary of State's office.

County clerks for Oregon's 36 counties were tasked with appointing counting boards of four people to conduct the recount by hand. The recount will begin at various counties on Tuesday and must be completed by Dec. 12.

Measure 92 would require food with genetically modified ingredients to carry a label saying, "Produced with genetic engineering."

The results were too close to call on election night. By the following morning, FOX 12 political analyst Tim Hibbitts projected the measure would fail.

Further analysis, however, showed a trend that had a higher percentage of "yes" votes than previous returns. There were also 13,000 voters who had signature problems with their ballots that were not initially counted.

Elections officials sent letters to those people, who had a week to resolve the issue and have their votes counted.

After saying the final results would fall within the range of a recount, Hibbitts called the chances of Measure 92's defeat being overturned "extremely unlikely."

"In all probability, with an 800 vote edge, the no side vote will stand up, but there's an infinitesimal chance that there could be some glitch somewhere where we could get a flip," Hibbitts said. "But, again, I have every expectation this narrow defeat is going to hold up."

One advocate for and one against Measure 92 are permitted to observe each counting board during the recount in each county.

Measure 92 was the most expensive race in the history of Oregon, with the two sides raising more than $25 million collectively in the run-up to Election Day.
