FOOD IRRADIATION

Food Irradiation is a radiation technology used to reduce the pathogens in foods. Depending on the dose, microorganisms, bacteria, and viruses present are destroyed, slowed down, or rendered incapable of reproduction. This reduces or eliminates the risk of foodborne illnesses. Some foods are irradiated at sufficient doses to ensure that the product is sterilized and does not add any spoilage or pathogenic microorganisms into the final product.[1]
