Supporters of the idea turned in petitions at the end of last week.
Sandeet Kaushik with Oreogn GMO Right to Know, says they got more than enough signatures to qualify for the November ballot.
"We turned more than 166,000 signatures in. We collected them over the last six weeks, which we did over a pretty short period of time. We had some paid signature gatherers, but we also had hundreds of volunteers. 87.2000 some signatures are required and we had nearly double that."
Twelve years ago, Oregon voted on labeling GMI foods, but that measure went down to defeat.
Supporters feel support on this issue has increased in the state since then.
