TRIAL OF HEAT INACTIVATION OF SELECTED VIRUSES FOLLOWING IRRADIATION

Four selected viruses were irradiated in ground pork with an electron beam at absorbed doses of 4.1 to 5.27 kG. Irradiated and nonirradiated viruses were heated at four temperatures for four time intervals and assayed for surviving virus. Data were examined for evidence of irradi ation-heat interaction to determine whether absorbed irradiation would sensitize virus set that a lesser amount of heat would be required fo r inactivation. It was determined that irradiation does not increase l ability to heat to a level that has practical application in virus ina ctivation.
