Irradiation is the process by which an object is exposed to radiation. The USDA states, “Food irradiation is a process in which approved foods are exposed to radiant energy, including gamma rays, electron beams, and x-rays. In 1963, the Food and Drug Administration (FDA) found the irradiation of food to be safe.”
Food manufacturers may provide a statement confirming that their internal process does not include irradiation. While many companies don’t irradiate their food as a part of their normal food production process, imported products it may undergo a random and unavoidable x-ray checkpoint at the port of entry for safety purposes.
