Eight cases of listeria infection across Australia have found to be linked and a further three cases are under investigation.

Victoria’s chief health officer Rosemary Lester said consumers should discard 1kg brie and camembert cheese branded Jindi, the 1kg Wattle Valley double brie and the 1kg Wattle Valley camembert with a best before date of December 21.

Dr Lester warned consumers to check the best before date of any Jindi or Wattle Valley soft cheeses.

Two Victorians, three NSW residents and one person in Queensland, Tasmania and Western Australia have been diagnosed with the infection.

“Symptoms of illness can take up to 70 days to appear.”
