Cereulide Contamination in Infant Formula Containing Arachidonic Acid Oil: A Multi-Country Food Safety Alert and Global Regulatory Concern

Abstract:

The recent multi-country recall of infant formula contaminated with cereulide toxin has raised significant concerns regarding food safety, infant health, and global supply-chain surveillance. Cereulide, a heat-stable cyclic dodecadepsipeptide produced by emetic strains of Bacillus cereus, is resistant to conventional food-processing conditions and may cause serious toxicological risks, particularly in infants. This review aims to provide a comprehensive overview of the recent cereulide contamination event associated with Arachidonic Acid (ARA) oilcontaining infant formula and to summarize current knowledge regarding its toxicological properties, contamination pathways, analytical detection methods, clinical implications, and regulatory challenges. The review discusses the biosynthesis and mechanism of action of cereulide, the role of lipid-rich ingredients such as ARA oil as potential contamination vectors, and the public health consequences of large-scale international recalls. Recent advances in toxin detection, risk assessment, traceability systems, and Hazard Analysis and Critical Control Point (HACCP)-based preventive strategies are also examined. Furthermore, existing knowledge gaps related to contamination dynamics, infant-specific risk assessment, and harmonization of international regulatory standards are highlighted. By integrating current scientific evidence and regulatory developments, this review provides researchers, food safety authorities, healthcare professionals, and infant formula manufacturers with a structured understanding of cereulide contamination. It identifies priorities for future surveillance and prevention strategies aimed at safeguarding infant nutrition products worldwide.
