Hawaii Congresswoman Tulsi Gabbard is calling for people to oppose a bill that would prohibit states or local governments from requiring mandatory labeling on genetically engineered food.

House Bill 4432 was introduced by Rep. Mike Pompeo, a Republican from Kansas, and Gabbard said in a campaign email Tuesday that Congress could vote on it any day now.

“One of the best is our ability to grow our own food, and to do it in a way that’s sustainable,” said the Democrat representing Hawaii’s 2nd congressional district. “But our farmers and our communities are dealing with huge multi-national agribusiness corporations that keep their use of GMOs secret from consumers. That’s just plain wrong. Each of us has a basic right to know what’s in our food. Now is the time to call for action.”

She linked to an online petition calling for mandatory GMO labeling that’s already garnered over 28,000 signatures, and threw in a link requesting campaign contributions at the bottom of the email.

In Gabbard’s district, which includes Kauai County, Maui County, the Big Island, and the rural parts of Oahu, GMOs are fairly unpopular. Both Kauai and the Big Island passed regulations on GMO farming that were struck down in court. Last fall, Maui County voters approved a ballot initiative to temporarily ban GMO farming, but lawsuits from Monsanto and Dow AgroSciences have so far prevented the law from going into effect.
