It provides detailed assessments of the safety of residues from selected veterinary drugs, including imidacloprid and nicarbazin, based on proprietary data submitted for JECFA's review. The monographs contained within this volume offer insights into the biochemical aspects, toxicological studies, and effects of these substances. The work serves as a scientific advisory resource for the FAO, WHO, member states, and relevant committees, aiming to inform policy and regulatory decisions regarding food safety. This book is intended for experts and stakeholders in food safety, veterinary medicine, and related fields, providing vital information for ensuring the safety of food additives and residues.
