Abstract
Food irradiation is a scientifically validated and internationally endorsed technology that
applies ionizing radiation to improve the microbiological safety and shelf life of food products.
By effectively inactivating pathogens, parasites, and pests without significantly compromising
nutritional or sensory quality, irradiation serves as a potent alternative to conventional
decontamination methods. This review provides a comprehensive analysis of the scientific
principles underlying irradiation, detailing the mechanisms of action, microbiological efficacy,
toxicological safety, and minimal impact on nutritional value. These findings are supported by
extensive evaluations from authoritative bodies, including the World Health Organization
(WHO), the Food and Agriculture Organization (FAO), the International Atomic Energy
Agency (IAEA), the European Food Safety Authority (EFSA), and the U.S. Food and Drug
Administration (FDA). The paper also explores the regulatory landscape surrounding food
irradiation, with particular focus on the European Union’s limited list of approved irradiated
food categories under Directives 1999/2/EC and 1999/3/EC. The implications of regulatory
fragmentation within the EU and the contrasts with countries such as the United States, Canada,
India, and Thailand are assessed. Key applications, such as pathogen reduction in meat and
poultry, insect control in spices and grains, and phytosanitary treatment for exportable fruits are
discussed alongside economic and logistical benefits. Consumer perception remains a major
barrier to widespread acceptance, often shaped by misconceptions and negative associations
with the term “irradiation.” Strategies for effective communication, labeling transparency, and
public education are examined. The review further assesses CEN (the European Committee for
Standardization)-standardized and emerging detection methodologies critical for regulatory
enforcement and traceability. Finally, it highlights the role of irradiation in advancing climateresilient food systems, reducing post-harvest losses, and supporting global food security, while
calling for harmonized regulation and greater international cooperation.
