The document discusses lessons learned from efforts to achieve Universal Salt Iodization (USI) globally. Key points include: 1) Over 70% of households globally now consume iodized salt, though challenges remain in fully reaching USI and eliminating iodine deficiency disorders. 2) National commitment, effective monitoring programs, education efforts, and strategies to engage small salt producers are important factors in achieving USI. 3) Emerging issues include iodine deficiency in Europe, ensuring iodized salt is used in processed foods, and improving monitoring programs. 4) While progress has been made, continued efforts are needed to fully achieve USI goals and address technical challenges in all countries.
