Description:
Research was conducted to investigate the regrowth of salmonellae in composted sewage sludge. Though composting effectively stabilizes and disinfects sewage sludges, the decrease in salmonellae may be only temporary, since this pathogen can survive and grow without a human or animal host. Modification of an agar medium improved our ability to detect salmonellae in composts. Salmonellae was detected in four composts from 30 composting sites across the United States. To determine the nature of salmonella suppression in composts, they investigated the effects of groups of the compost microflora, and the characteristics of the substrates used by salmonellae in composts.
