What is food irradiation?

Preserves food. Food irradiation is the method of exposing food to ionizing radiation to stop or destroy microorganisms, bacteria, viruses, or insects that might be present in the food. The irradiation damages genetic dna so that germs and insects cannot survive or cannot reproduce. The food does not become radioactive, but there can be mild chemical changes in the foods.
Improve safety . Food irradiation is the application of ionizing radiation to food in order to improve the safety and extend the shelf life of foods by decreasing or eliminating microorganisms and insects. The FDA, World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC) and the U.S. Department of Agriculture (USDA) have endorsed the safety of irradiated food.
