The Food and Agriculture Organisation of the United Nations (FAO) recently published a “Guide to Ranking Food Safety Risks at the National Level”. The objective of this guide is to provide direction to decision-makers on how to start ranking the public health risk posed by foodborne hazards and/or foods in their countries. The guidance focuses on the ranking of microbial and chemical hazards based exclusively on their impact on public health. It covers various metrics, including disability adjusted life years (DALYs).
