Senate Bill No. 4 establishes new regulations regarding the use of specific substances in food products and ingestible drugs in Oklahoma. Effective January 15, 2027, the bill prohibits the manufacture, sale, or distribution of food products containing certain additives, including aspartame, various dyes, and other chemical substances. Additionally, starting January 18, 2028, the same restrictions will apply to additives used in reformulating ingestible drugs. The bill mandates that any products containing these substances must disclose their presence on labels, websites, or via QR codes, with a conspicuous warning to consumers.

The bill also empowers the Oklahoma Department of Agriculture, Food, and Forestry to enforce these regulations through administrative penalties for violations, which can amount to $5,000 for subsequent offenses. The department can also seek injunctive relief through district courts to ensure compliance. Any penalties collected will be directed to the State Department of Agriculture Revolving Fund, specifically for the Oklahoma Farm to School Program Act. The State Board of Agriculture is tasked with creating the necessary rules to implement these provisions, with the act set to take effect on November 1, 2025.
