The WTO Sanitary and Phytosanitary (SPS) Agreement aims to protect human, animal and plant life from risks arising from additives, contaminants, toxins, or disease-causing organisms in their food. It recognizes standards set by Codex, OIE and IPPC to harmonize SPS measures between countries. The SPS Agreement requires that measures be based on scientific principles and risk assessment, be non-discriminatory, and be no more trade-restrictive than necessary to protect health. Problems in implementing the SPS Agreement include non-compliance with international standards and lack of notification, awareness, and development in some areas.
