More than 92 % microorganisms was inactive at the irradiation dose of 4kGy, while more than 99 % was inactive at 6kGy. The microorganism load of irradiated pet food by 8kGy met the requirement of national standards. The 10kGy irradiation could sterilize the treated pet food. Salmonella had not been checked in irradiated or unirradiated samples. When irradiation dose ranged 4 10kGy, there was no significant difference on contents of moisture, fat, protein, coarse fiber, carbohydrates,minerals ( not including Calcium) or amino acids between irradiated and un2irradiated pet food. There was also no significant change on sensory quality of irradiated samples within this dose range. It is concluded that the recommended irradiation processing dose range for pet foods is 4 10kGy.
