The document discusses the Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement) which came into force in 1995. The SPS Agreement recognizes countries' rights to adopt science-based food safety, animal and plant health measures but aims to prevent such measures from being disguised protectionism. It establishes rules for risk assessment, harmonization of regulations, and transparency in the application of sanitary and phytosanitary measures. The SPS Agreement also includes provisions for technical assistance to developing countries and recognizes constraints they face in implementation.
