In the Netherlands, an estimated 35,000 cases of salmonellosis occurred in 2009, which equals around 212 cases per 100,000 inhabitants. Overall, based upon data from the Dutch laboratory surveillance network for gastroenteric pathogens, the incidence of salmonellosis in the Netherlands has decreased since 1997, with some peaks due to outbreaks. Almost every year, 15 to 20 outbreaks of salmonellosis are detected at a regional or national level.
The National Salmonella and E. Coli Centres are involved in identifying and typing Salmonella spp. and E. coli from within India and around the world.
