Laboratory testing has confirmed a Launceston bakery was the source of Tasmania’s worst salmonella outbreak. Sixty-four people have been infected with the bacteria over the past few weeks. Of the 64 people infected, six were taken to hospital but all have since been released.

The Trevallyn Bakery and the associated Sugar Shack bakery voluntarily closed last week after the outbreak was linked to their products.

The Public and Environmental Health Service says tests have identified salmonella in piping bags, used to dispense cream and icing, at the Trevallyn Bakery.

The director of Public Health, Roscoe Taylor, says it is highly likely a lack of hygienic controls at the bakery allowed other food to become infected.

Dr Taylor says the bakeries will be allowed to reopen once staff have received training in food safety and tests have confirmed the cleanliness of the premises and safety of food products.
