Salmonella enterica is one of the most important foodborne pathogens for public health worldwide. When Salmonella enterica is exposed to low water activity, changes in cellular behavior may occur. These changes can impact the cells that form a colony on specific nutrient media (culturability) and the metabolically or physiologically active cells (viability) of Salmonella cells, with consequences for the analytical methods and food safety management. Thus, this study studied the impact of continuous and recurrent exposure of S. Senftenberg IOC 2319 and S. Typhimurium ATCC 14028 to water activity (a
