Instructs the department of social services to apply for a waiver to the USDA to allow SNAP to prioritize the purchase of healthy food and discourage the purchase of highly processed foods

HB 1889 directs Missouri's Department of Social Services to request a federal waiver from the USDA to modify the SNAP (food stamp) program. If approved, the waiver would allow Missouri to prioritize SNAP benefits for healthy foods like fresh produce, lean proteins, dairy, whole grains, and legumes while discouraging purchases of highly processed foods. The bill specifically requires the state to design these changes to support Missouri agriculture by promoting locally produced healthy foods through existing education and access programs. It affects SNAP recipients in Missouri by altering how benefits can be used for grocery purchases. The measure focuses on program structure, not outcomes or advocacy.
