（3）卫生与动植物卫生措施协定涉及食品安全和人类、动植物安全和健康规范。该协定认可成员方制定SPS措施的权利，但规定这些措施必须以风险评估为基础，不得对贸易造成不必要的壁垒（应当仅在保护人类、动植物生命和健康的必需程度内实施），并且不应在相同条件的成员方之间形成无端的、不合理的歧视。该协定鼓励成员方根据为其供应进口的领域的差别（地区、国家或国家的部分领土）来调整SPS措施。
SPS协定对技术贸易壁垒协定来说起到了补充的作用。它允许成员方为环境目的制定SPS措施，但需要满足一定的条件，例如风险评估、非歧视和透明度等。
Members,
Reaffirming that no Member should be prevented from adopting or enforcing measures necessary to protect human, animal or plant life or health, subject to the requirement that these measures are not applied in a manner which would constitute a means of arbitrary or unjustifiable discrimination between Members where the same conditions prevail or a disguised restriction on international trade.
