VAAL TRIANGLE - Vaal Triangle residents can rest assured as it seems the deadly listeriosis outbreak that hit the nation earlier this year is now well and truly under control. The National Institute for Communicable Diseases reports the number of reported listeriosis cases across the country is steadily decreasing. The NICD’s Lucille Blumberg says during the last six weeks, there has been less than five cases per week. Blumberg says a steady decline can be seen since the products were recalled. The listeriosis outbreak was the deadliest outbreak on record globally which claimed 209 lives. The majority of those cases were reported in Gauteng.
