California passes bill to ban 6 dyes in school food

California could soon become the first state in the US to ban artificial color additives in food served in K-12 public schools. On Aug. 29, lawmakers passed the California School Food Safety Act (AB 2316). The bill now heads to Governor Gavin Newsom, who must either sign or veto it by the end of September.

The legislation targets six synthetic food dyes—Red No. 40, Yellow No. 5 and No. 6, Blue No. 1 and No. 2, and Green No. 3—that California’s Office of Environmental Health Hazard Assessment has linked to hyperactivity and other adverse behavioral effects in some children. It would prohibit public schools in California from serving or selling food that contains any of the chemicals, effective Dec. 31, 2027. Children could still eat food containing the dyes at school, as long as it was brought in from elsewhere. Food sold in schools for fundraising purposes would also be exempt from the ban.

California has the largest public school system in the US, with nearly 6 million students and more than 10,000 schools.

“California has a responsibility to protect our students from chemicals that harm children and interfere with their ability to learn,” Assemblymember Jesse Gabriel, who introduced the bill, says in a statement in response to the bill’s passage. “This bill will empower schools to better protect the health and wellbeing of our kids and encourage manufacturers to stop using these harmful additives.”
