Johannesburg - Four countries in southern Africa on Monday took steps against South African chilled meat imports made at a factory found to be the origin of the world's worst-ever listeria outbreak.
Mozambique and Namibia announced they were immediately suspending imports of the products. Botswana said it was recalling the items "with immediate effect", while Zambia called on South African retail chains in its country to pull the incriminated goods from local shelves.
Since January 2017, 948 people in South Africa have contracted listeriosis - a disease caused by bacteria from soil, water, vegetation and animal faeces which can contaminate fresh food, notably meat.
At least 180 have died, according to official figures.
Health officials say the source of the outbreak was an Enterprise Food plant in Polokwane. The Wolwehoek Rainbow Chicken in Sasolburg in the Free State was also issued with a notice of closure after it was identified as one of the sources of the Listeriosis outbreak.

Queues formed outside Enterprise sites in the country as angry consumers and small retailers gathered to demand refunds on their purchases of ready-to-eat meat products that include polony sliced ham and Frankfurter-style sausages.
"I've eaten already some polony and Russian. I don't know, maybe I can get some disease," said taxi driver Bongani Mavuso as he queued outside Enterprise's factory shop in Germiston, Johannesburg to seek a refund. "I'm just coming to collect my money."
On Sunday, Health Minister Aaron Motsoaledi took the unprecedented step of advising South Africans to avoid eating all processed meat products sold as "ready-to-eat" after announcing Enterprise as the outbreak's source.
The Department of Health ordered retailers to immediately recall affected products.
The chief executive of Tiger Brands, which owns Enterprise, denied that its products had been shown to be responsible for the deaths.
"There is no direct link with the deaths to our products," Lawrence MacDougall told a news conference.
MacDougall did acknowledge that the government had linked the ST6 strain of listeria bacteria detected in Enterprise facilities with the outbreak that has resulted in 180 deaths.
"We are being extra cautious and vigilant. We are recalling all products made from the two facilities" affected, he said, adding that the government had only ordered the company to withdraw three product lines.
"Any loss of life is tragic. It is devastating for me to have our products linked to this outbreak."
Enterprise-branded products accounted for 28.2 percent of processed meat sales in South Africa in 2017. The local market was worth R6.02 billion last year alone.
Tiger Brands, one of South Africa's food giants, made pre-tax profits of R4.27bn in 2017.

South Africa's two largest supermarket operators, Shoprite and Pick n Pay, have also pulled products made by Rainbow Chickens after Motsoaledi confirmed that listeria had been identified in samples taken from one of its facilities.
Motsoaledi said on Sunday that Enterprise and Rainbow Chicken's registration to export their products outside of South Africa had been temporarily suspended. Namibia also said it was suspending imports from Rainbow Chickens.
As fears of listeria continued to rise in South Africa, several other smaller food retailers have also announced product recalls.
High-end food chain Woolworths announced it was recalling dozens of sausage and ham products "as an additional precautionary measure".

Zambia's High Commissioner to Pretoria Emmanuel Mwamba called on South African supermarket chains operating in his country to also recall ready-to-eat meat as a precaution.
"Chain stores should emulate measures put in place by the South African government," he said in a statement.
Mozambique Agriculture Ministry spokeswoman Florencia Cipriano told reporters on Monday that officials were working with importers to halt the flow of South African chilled meat products.
The United Nations has previously said South Africa's listeriosis outbreak is believed to be the largest-ever worldwide.
The infection mainly affects children and has a three-week incubation period, making it difficult to track.
Contamination in humans - especially those with compromised immune systems - can result in flu-like illness, infection of the bloodstream and, in severe cases, infection of the brain which can prove fatal.
