This means that 134 actual patients were traced to their health facilities, i.e as to what eventually happened to them. We await confirmation of the strain testing to confirm the strain.
We are all extremely concerned by Listeriosis - we all want to find the source or sources of Listeriosis, together with government. That is why we have called you here to brief you. As of 16 January, 764 cases had been reported nationally with 212 in Johannesburg.
A chilly, handled meat item made by South Africa's greatest maker of buyer sustenances is the reason for the progressing outbreak, which has a shocking 27 percent casualty rate.
In our constant search for the source of the outbreak and the treatment of people who are affected, a team from the NICD has interviewed 109 ill people to obtain details about foods they had eaten in the month before falling ill.
South Africa began investigating the outbreak on January 12 after a pediatrician treating nine children younger than 5 at Chris Hani Baragwanath Hospital suspected a foodborne disease was involved, including listeriosis. A paediatrician who suspected listeriosis alerted inspectors, who visited the crèche the children attend.
Rainbow Chicken polony is also a cause of listeriosis. These isolates were sent to the NICD Centre for Enteric Diseases, and underwent whole genome sequencing and genomic analysis.
All three samples showed the presence of sequence type 6 (ST6) bacteria, the specific strain that is strongly believed to be behind the South African outbreak.
"To conclude the investigation, whole genome sequencing analysis was performed from this Enterprise factory".
"While we know that polony is definitely implicated, there is a risk of cross-contamination of other ready-to-eat processed meat products, either at production, distribution or retail. Recalled meat is being isolated and will be safely destroyed", Pick n Pay, which has 1,420 stores in South Africa, said in a statement.
Listeria has been traced to another Enterprise facility in Germiston on the East Rand, and a Rainbow chicken facility in the Free State, but further tests were needed as the sequence type was not yet known. Such products could be cross-contaminated in shops as they are often stored next to polony. "Also, over 10% of environmental samples collected by the EHPs at this facility have tested positive for L. Monocytogenes".
National Consumer Commission deputy commissioner Thenzi Mabuza said "companies would have to come up with a plan on how they would recall all products which they must present on Monday morning".
"We advise members of the public to avoid all processed meat products that are sold as ready-to-eat", Motsoaledi said.
"This is on the grounds that Listeria on the outside packaging (bundling) of polony can be exchanged to different products it comes into contact with, including viennas, russians, hotdogs, different wieners, and other "cool meat" products that are ordinarily not cooked before eating".
Those at high risk of developing severe disease include newborns, the elderly, pregnant women, persons with weak immunity such as HIV, Diabetes, Cancer, Chronic liver or Kidney disease.
