Three food manufacturers have been issued with safety recall notices after being identified as the source of the listeriosis outbreak in the country. The symptoms of listeriosis include fever, muscle aches, and sometimes nausea or diarrhea. If infection spreads to the nervous system, symptoms such as headache, stiff neck, confusion, loss of balance, or convulsions can occur.
Tiger Brands, on behalf of its division Enterprise Foods, has committed to recalling products that are identified with listeriosis outbreak, but are conducting its own tests as well. 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.
“The company proactively amplified its testing for listeria and can confirm that we had found a low detection of a strain of listeria in some products on 14 February but the presence of the ST6 strain [the outbreak strain] has not been confirmed by our tests.
“The company has furthermore sent its samples to an external laboratory to test for the strain itself and should receive the results tomorrow [Monday].”
