The Farmers' Market Expansion Act of 2025 seeks to amend the Farm Security and Rural Investment Act of 2002, specifically targeting the Seniors Farmers' Market Nutrition Program . The core purpose is to expand the range of eligible food items that participants can purchase through this program. The bill achieves this by modifying Section 4402(b)(1) of the 2002 Act to explicitly include tree nuts , including shelled tree nuts, alongside the currently allowed fruits, vegetables, and herbs. This provision aims to offer seniors a more diverse selection of nutritious foods, thereby enhancing their dietary choices and supporting local agriculture.
