The Australian Health Department says it has found no evidence of contamination at the factory of an egg supplier it has been investigating as the possible source of the recent salmonella outbreak, according to ABC News.
Seventeen people have been infected with the bacteria and six of those cases have been linked to ravioli products made by Adelaide company Buona Pasta. It had been thought the source of the contamination may have been eggs used in the pasta recipe.
Director of public health Dr Kevin Buckett says authorities will now have to consider other possibilities.
