California AG Issues Warning Letter to Baby Food Manufacturers re Heavy Metal Testing Disclosures

Short summary

California's Attorney General issued an enforcement letter reminding baby food manufacturers of their AB 899 obligations: test for heavy metals (arsenic, cadmium, lead, mercury) monthly and publicly disclose results on their websites. Manufacturers must maintain disclosures for product shelf life plus one month. Non-compliance can violate California's Unfair Competition Law and face enforcement action.

  • AB 899 mandates monthly heavy metals testing (arsenic, cadmium, lead, mercury) for baby food sold in California
  • Results must be publicly disclosed on manufacturer websites starting January 2025
  • Pending AB 2302 would extend similar requirements to infant formula
