Tiger Brands said on Friday it had re-opened a facility that was closed after South Africa's biggest food producer was implicated in the world's largest outbreak of listeria which killed more than 200 people.
The health department recalled processed meat products known as "polony" and closed some processing facilities after the source of the outbreak was traced to a factory owned by Tiger Brands unit Enterprise Foods in March.
The incident prompted the company to suspend production at its Polokwane and Germiston facilities which produce polony and other cold meats and resulted in a class action lawsuit filed against the company.
Tiger Brands said production of its ready-to-cook products including bacon and frozen sausages is expected to begin on Friday at its Germinston processing facility, east of Johannesburg after the municipal health department gave it the go-ahead.
The firm said it was continuing refurbishments at Polokwane which it expects to complete early next month.
"It is showing signs of returning to normalcy again after that horrible black cloud was hanging over them so investors, in general, are looking a little bit more confident," said Ryan Woods, a trader at Independent Securities.
Tiger Brands has shed more than a third of its market value, some 28.4 billion rands ($1.96 billion), since it was implicated in the listeria outbreak on March 4.
