"Whoever is behind this is not just putting families at risk across Queensland and the rest of Australia - they are putting an entire industry at risk", Queensland Premier Annastacia Palaszczuk said Saturday.
An urgent recall was originally issued on Wednesday following the discovery of needles planted inside the fruit, with Queensland's Chief Health Officer Dr Jeannette Young advising anyone who has purchased strawberries from the Berry Liscious and Berry Obsession brands to dispose of their fruit immediately.
Officials said it is still safe to buy strawberries but consumers should cut them up before eating them.
"I won't go as far as saying we have specific leads. We have to come together".
The concerned consumer handed in the infected product to their local police station after they found the three sharp objects inside the berry.
One man was taken to hospital after eating a strawberry with a needle inside.
The contamination is believed to have affected the brands "Berry Obsession", "Berry Licious", "Love Berry", "Donnybrook Berries", "Delightful Strawberries", and "Oasis". He is being assessed by medics but his condition is not known.

Coles supermarkets across the country, except for West Australian stores, will pull all Queensland-grown strawberries from the shelves as a precaution over needle contamination fears.

The statement added: "As the products have yet to be forensically examined, it is unknown if the contamination is related to the original Queensland incident or a copycat".
He said unless confidence and sales recovered quickly, growers would have to leave strawberries on the ground to rot.
Some Australians have posted photos on social media showing needles they found in their berries.
NSW police say they are continuing to liaise with retailers to ensure that all stock from the affected date has been removed from sale.
