The US state of West Virginia has passed a sweeping ban on seven artificial food colors and additives, citing potential health risks, amid sharp criticism from industry associations. The move comes amid a national crackdown on synthetic food dye that gathered steam with the FDA outlawing red dye No. 3 earlier this year. Governor Patrick Morrisey signed a bill into law that prohibits the usage of Red Dye No. 3, Red Dye No. 40, Yellow Dye No. 5, Yellow Dye No. 6, Blue Dye No. 1, Blue Dye No. 2, and Green Dye No. 3 as an ingredient in food products and school lunches from August 1.
