On World Food Safety Day 2026, we highlight the theme "From burden to solutions: safe food everywhere." This emphasizes the critical need for both science-based evidence to understand foodborne disease risks and practical solutions to address them. FAO is dedicated to helping countries translate this evidence into effective action, identifying priorities, and allocating resources efficiently.

We support Members in strengthening food control systems, developing international standards under the One Health framework, and building national capacity to manage risks. These efforts reduce illness, protect public health, and foster economic development. Food safety is everyone's business—governments, businesses, and consumers all play a vital role. Through sustained commitment and science-based solutions, we can ensure safe food for all.
