Is salmonella contagious even after the symptoms end?
Although most cases of Salmonella are contracted from contaminated food or water, it can also be spread from person to person. Yes, a person can continue to be contagious after their symptoms have disappeared. In most areas, if a stool culture tests positive for Salmonella, the local public health department will contact that individual and if he/she happens to work in an occupation where he/she prepares food, cares for the elderly, children, or the ill, then the medical officer of health may order them to stop working until two consecutive stool samples have tested negative for Salmonella.
