What law pertains to salt iodization on a national scale in the Philippines?

The law that pertains to salt iodization on a national scale in the Philippines is Republic Act 8172, also known as the "Salt Iodization Nationwide Program Act." This legislation was enacted to address the public health issue of iodine deficiency, which can lead to various health problems, including goiter and intellectual disabilities. The act mandates the iodization of all salt produced and sold for human and animal consumption, ensuring that the entire population has access to iodized salt, thereby improving overall nutritional health.

Republic Act 8172 specifically outlines the responsibilities of both the government and the salt industry in implementing the iodization program. It also emphasizes education and awareness campaigns to inform the public about the benefits of iodized salt, contributing to the reduction of iodine deficiency disorders in the country.

Other options refer to different laws—Republic Act 9003 focuses on ecological solid waste management, Republic Act 8976 pertains to the nutrition labeling of food products, and Republic Act 10611 covers the Food Safety Act, which relates more broadly to food safety and consumer protection rather than specifically addressing salt iodization.
