microbiological problems in foods. In September 1997 a Study Group was jointly convened by the WHO, FAO and IAEA to evaluate the wholesomeness of food irradiated with doses above 10 kGy. This Study Group concluded that there is no scientific basis for limiting absorbed doses to the upper level of 10 kGy as currently recommended by the Codex Alimentarius Commission. Food irradiation technology is
