Inactivation by ionizing radiation of Salmonella enteritidis serotype montevideo grown in composed sewage sludge

S. enteritidis ser. montevideo were grown in composted sewage sludge to levels of approximately 10(9)/g. These bacteria were found to be inactivated by ionizing radiation at approximately the same rate (30 krads/log) as Salmonella species in liquid digested sludge.
