This book, prepared by the ninety-first meeting of the Joint FAO/WHO Expert Committee on Food Additives (JECFA), presents a comprehensive evaluation of certain contaminants in food. It contains detailed monographs summarizing the data reviewed by the Committee on selected food contaminants, based on unpublished proprietary data. The primary focus is on safety assessments and dietary exposure evaluations of contaminants like cadmium and ergot alkaloids. The publication serves as a scientific advisory resource to international bodies like the Codex Alimentarius Commission and provides insights into the safety of food additives and residues of veterinary drugs. It is intended for regulatory authorities, researchers, and policymakers involved in food safety and public health.
