Citing potential health risks, West Virginia signed into law a ban of seven artificial food dyes and two preservatives from drugs and food sold in the state.

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.

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.
