public schools; ultraprocessed foods

HB 2164 prohibits Arizona public schools from serving or selling ultraprocessed foods during the school day, directly affecting school meal programs and cafeteria operations. The law defines "ultraprocessed food" as any item containing specific synthetic additives like certain dyes (e.g., Yellow #5, Red #40) or preservatives (e.g., potassium bromate), excluding foods parents provide to their own children. The Arizona Department of Education may create implementing rules but is not required to mandate specific alternatives. Signed into law on April 14, 2025, this policy aims to improve school meal nutrition by limiting low-nutrient processed foods.
