Health authorities in South Africa say 172 people have died this year from the food-borne bacteria, listeria.
Most of the more than 900 cases of listeriosis were in Gauteng province.
The government has not confirmed the source of the outbreak and has urged people not to panic unnecessarily as it tries to find the reason for the spike in cases.
The bacteria can be found in unpasteurised milk, meat and soft cheeses and the symptoms include high temperatures, vomiting and diarrhoea.
