This article answers the following questions: What is ionizing radiation? Which are their sources? Where they are applied? How they affect microorganisms and other pets? When they can be used for food items? Why consumers are reluctant to use ionized foods? Do they make food safe? Who allows and regulates their usage in the food industry?
Ionization radiations (beta and gamma) are used to ensure food safety and quality. This irradiation process inactivate or destroy the food spoilage pests, microorganisms and their toxins without significantly increasing the temperature of the treated product. Meanwhile, various intrinsic and extrinsic factors are involved in determining the ecacy of ionization irradiation against these organisms. Therefore, the dose of radiations is recommended according to the type of irradiation, substrate, and microorganisms. However, controversies are surrounding the use of irradiations in the food industry due to a negative perception of irradiations.
This information is a guide for teachers, scientists, field experts and for consumers regarding the ionizing radiations, their usage, mode of action, required doses, limitations, consumer values and regulations. Dr. Muhammad Tanveer Munir, DVM, MS
