West Virginia has banned most foods containing artificial food dyes. Gov. Patrick Morrisey (R-WV) on Monday signed into law a bill banning Blue No. 1, Blue No. 2, Green No. 3, Yellow No. 5, Yellow No.

West Virginia has outlawed foods that contain some artificial dyes or other additives, in one of the most comprehensive statewide bans of its kind. The move cites potentially harmful health effects and comes amid a broader push from scientists and government leaders to clamp down on synthetics in the nation's food supply.

Governor Patrick Morrisey signed House Bill 2354 into law, which prohibits certain harmful food dyes from being used as an ingredient in school lunches and in food items throughout West Virginia.
