The South Australian Health Department says it will not make public the name of the egg company with a possible link to a salmonella food poisoning outbreak.
The source of six cases of Salmonella food poisoning was first traced back to the Buono Pasta Company at Klemzig. Batches with best before dates of September 20 and 27 have been recalled as a precaution.
The Health Department says the pasta company does not appear to be at fault because the people who became sick reportedly ate the pasta raw. However, the department says a further 11 people who have not eaten the pasta have become sick with the same strain of salmonella.
Department Director Kevin Buckett says eggs used as an ingredient could be the source of the contamination.
"But in this case the eggs are still just a working hypothesis," he said.
