The investigation showed that the outbreak was linked to chocolate produced in Belgium, which had been sold to at least 113 countries and regions, including China.

  Salmonellosis is a disease caused by non-typhoid Salmonella bacteria.

Although approximately 2,500 serotypes have been identified, most human infections are caused by two serotypes of Salmonella: Typhimurium and Enteritidis.

  Prevention of salmonellosis requires control measures at all stages of the food chain, from agricultural production to food processing, manufacturing and preparation in commercial establishments and households, WHO said.
