• The Wisconsin State Assembly introduced Wisconsin Assembly Bill 550 (AB 550) on October 15, 2025. The bill proposes a mandate that manufacturers of packaged food products intended for human consumption must include prominent warning labels if the product contains any of the fifty-one ingredients listed in the bill.
  • Ingredients that would require a warning label include certain artificial colors, sweeteners, preservatives, and other additives, including the FD&C certified colors, titanium dioxide, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), acesulfame potassium, and more. Foods containing these ingredients would be required to bear the label “WARNING: This product contains an artificial color, chemical, or food additive that is banned in Australia, Canada, the European Union, or the United Kingdom.”
  • The bill follows similar laws that were recently enacted in Texas and Louisiana, as we previously blogged. Unlike the Texas law, there is no preemption provision in AB 550.
  • Keller and Heckman will continue to monitor this and other bills related to food labeling.
