SALMONELLA SELECTIVE PRIMARY BROTH

Salmonella Selective Primary Broth is a pre-enrichment medium designed to help recovery Salmonellae before transfer to a selective medium. This pre-enrichment medium is free from inhibitors and is well buffered and provides conditions for resuscitation of the cells that have been injured by processes of food preservation. It was noted by Edel and Kampelmacher that sub-lethal injury to Salmonella may occur due to food preservation techniques involving heat, desiccation, high osmotic pressure, preservatives or pH changes. This is particularly important for vegetable specimens, which have low buffering capacity. This medium can be used for testing dry poultry feed. Lactose Broth is frequently used as a pre- enrichment medium but it may be detrimental to recovery of Salmonella.
