Fears over needles secreted in strawberries have now spilled across the Tasman, with one of New Zealand's two major food distributors taking the fruit off its shelves as a precaution.
Police are investigating after metal pins were found in punnets of fruit in five different states.
Federal Health Minister Greg Hunt has ordered the food safety watchdog to investigate Queensland's handling of the strawberry spiking saga.
"We have also tasked the federal agency to investigate whether there are supply chain weaknesses, whether there are actions that we can take to assist the police, whether there are systemic changes which are required," Mr Hunt told the ABC on Monday.
"At the end of the day, the job is very, very clear. Protect the public and keep them safe."
Mr Hunt said the "vicious crime" was not only designed to injure or kill members of the public, it was also an attack on the agricultural sector.
Foodstuffs - which supplies various chains that make up about half of New Zealand's grocery store market - in a statement on Monday said it had stopped shipping Australian strawberries to its stores.
The announcement comes as needles were found inserted into more strawberries in South Australia and NSW over the weekend, adding to incidents across the country and prompting fears of copycat behaviour.
