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.

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.

A 2021 review of scientific studies by California state scientists concluded that consuming the dyes may increase hyperactivity and other behavioral problems in some children. The F.D.A. has maintained that food dyes (with the exception of Red No. 3) are safe when used according to regulations.
