Police began looking into the potentially risky berries after a Facebook user on Saturday wrote that their friend took a bite of a strawberry and ate "half a sewing needle", according to the Palm Beach Post.
A couple in Gladstone found a needle inserted into a strawberry on Tuesday, after their nine-year-old son bit into the booby-trapped fruit.
Needles have been found in strawberries sold in Woolworths stores.
Acting Detective Chief Superintendent Lawrence said officers were looking into unconfirmed reports of contamination involving other strawberry brands.
Police have been unable to confirm whether the contaminated products are linked to the original contamination in Queensland or a copycat, however they are urging anyone who has purchased contaminated products to take the punnet to their local police station immediately for forensic testing.
He urged anyone who found a needle in a strawberry to provide this to police.
The Queensland Strawberry Growers' Association says a disgruntled farm worker may be responsible, as the two brands affected, Berry Obsession and Berrylicious, came from the same farm.
The strawberries believed to have contained the needle that injured Hoani Hearne was reportedly sold at a supermarket in Brisbane.
Australians have been warned to cut fresh strawberries before biting into them after several people found sewing needles hidden inside the fruit.
English Premier League: Liverpool 2-1 Tottenham
Jurgen Klopp described Liverpool's performance in the 2-1 win at Tottenham as their best so far in a ideal start to the season. Liverpool are scheduled to play seven games in the next 23 days starting with the weekend's trip to Wembley on Saturday.
Berry Obsession, Berry Licious, Love Berry, Donnybrook Berries, Delightful Strawberries, and Oasis are the brands affected.
Yesterday, Queensland police announced they were investigating a suspected copycat incident after a metal rod was discovered on top of strawberries inside a plastic punnet at a Coles in Gatton. "We're keeping a very open mind as to where this may have occurred".
One woman wrote on the post: "Sent my 7 year old to school with this brand strawberries this morning".
Authorities said on September 13 that they believe that they had mitigated enough risk for customers to buy strawberries again, as all stock had been replaced.
Police are checking every step of the production chain, and they say strawberries purchased from Thursday are safe.
"I know that farmers that are still going would appreciate the support by the public".
"But at this stage, please cut them up and just look to make sure they haven't been contaminated", Dr Young said.
'If you are in doubt, just throw them out'.
"We have withdrawn Berry Obsession and Berry Licious branded strawberries from sale while this incident is being investigated with our suppliers".
