What changes to food are caused by irradiation?
Irradiation causes minor chemical modifications, similar to cooking, and some irradiated foods may taste slightly different. Food irradiation does not lead to change in the food that, from a toxicological point of view, would have an adverse effect on human health. Food irradiation, at permitted levels, does not diminish the nutritional value of the food. Any living cells in the food, including potentially harmful bacteria, are killed or damaged.
