A semi-dried tomato product mixed with garlic, herbs and oil has been linked to a spike in hepatitis A cases in at least three states, Australian health authorities say.
South Australian director of public health Kevin Buckett says there have been 26 cases in the state since March, more than 70 in Victoria and an increased number in Queensland.
The cases are thought to be linked to the tomato product, which is manufactured in both Victoria and Queensland and sold in various states by weight.
Queensland Health Deputy Director-General Aaron Groves says an investigation into the possible contamination of unpackaged, loosely purchased semi-dried tomatoes is underway.
