Lactose Broth is frequently used as a pre-enrichment medium when testing foods, water samples and dairy products for Salmonella spp. In dried or processed foods, Salmonella species may be sublethally injured and present in low numbers. Pre-enrichment in a nonselective medium such as Lactose Broth allows for repair of cell damage, dilutes toxic or inhibitory substances, and provides a nutritional advantage to Salmonella spp. over other bacteria.
