Idaho lawmakers are requesting the federal government to ensure that all genetically modified food labels are voluntary.
The Senate passed the non-binding resolution by voice vote Friday.
Republican Sen. Jim Rice from Caldwell told lawmakers that a patchwork of state labeling laws would be too complex for manufacturers and could raise food prices.
Rice says the Food and Drug Administration should make the rules standard across the county.
The House has already passed the request 41-24 last week.
Oregon voters defeated a measure last November that would have required labels for genetically modified food by roughly 800 votes.
