Abstract

The wholesomeness of 40 kGy irradiated ready-to-eat (RTE) bulgogi was evaluated by subacute toxicity studies (body weight, food consumption, organ weight, hematology, serum biochemistry, and histopathological examination) with groups of 40 male and female ICR mice fed the agent at dietary levels of 5% for 90 days. There were no treatment-related adverse effects with regard to body weight, food consumption, organ weight, hematology, serum biochemistry, and histopathology. The no-observed-adverse-effect-level (NOAEL) was also determined to be greater than dietary level of at least 5% (3900 mg/kg body weight/day for males, 3500 mg/kg body weight/ day for females) for samples under the present experimental conditions. These results suggest that, under these experimental conditions, RTE bulgogi irradiated at 40 kGy did not show any toxic effects.
