Biotech critics are calling on Oregon lawmakers to overturn a prohibition against local government restrictions on genetically engineered crops because statewide regulations haven't been enacted. In 2013, the Oregon Legislature passed a law that preempted cities and counties from setting their own rules over seeds, which blocked most local ordinances banning genetically modified organisms, or GMOs. Groups that opposed the preemption bill say state inaction since then has justified the passage of House Bill 2469, which would carve out an exemption allowing local GMO regulations.
