Survival Strategies Used by Salmonella to Persist in Dry and Low-Moisture Processing Environments
Salmonella contamination in dry and low-moisture food processing environments is a food safety concern recognized by the FDA. For a microorganism to grow in a food processing environment, there must be enough available moisture for the organism to use. In a dry or low-moisture processing environment, there are typically not enough consistent sources of moisture for microorganisms to grow; however, Salmonella has shown the ability to adapt to this low-moisture stress and survive for long periods of time through accumulation of osmoprotectants, up-regulation of outer membrane porins, alteration of gene expression, rRNA degradation, entering a viable but not culturable state, filamentation, and biofilm formation.
