>> Zimbabwe has joined several other African countries in banning imports of processed meat from South Africa after a deadly listeria outbreak in the country, the world's worst ever recorded. South Africa's government blames producers of cold meat products for delays in tracing the cause. 180 people have died in the past year.
Shares in the country's biggest food firm Tiger Brands tumbled after a discovery that one of its meat products called Polony was linked to the outbreak. They've denied the direct link. The South African government said it was investigating a factory owned by RCL foods that makes a similar product too.
Both companies, which say they are cooperating with the authorities have suspended processed meat production at their plants. Almost 950 cases of listeria have been reported since January last year. It causes flu like symptoms, nausea, diarrhea, and infection of the blood stream and brain. Despite being present in South Africa for over a year, the source of the outbreak wasn't found until preschool children fell ill from eating Polony products traced to processed meat producers.
Since then, dozens of customers have been lining up outside of Tiger Brands outlet with bags of cold meat products demanding their money back.
