Chief health officer Jeannette Young said her advice remained the same following the latest discovery.
Those strawberries sold after Thursday are said to have been from a later shipment and are safe from the threat.
Chantal Faugeras posted on Facebook that she purchased the punnet from Wingham Coles on Wednesday, with three needles found inside three strawberries.
She urged anyone uncertain about the safety of their fruit to cut the strawberries in half before eating them.
Dr Young said she was particularly anxious about those who may have frozen the strawberries for use later and may not still have the packaging.
Det. Supt. Lawrence said officers were now identifying past and present employees of the two farms concerned, which involves more than 100 people, with plans to interview them.
Berry Obsession, Berry Licious, Love Berry, Donnybrook Berries, Delightful Strawberries, and Oasis are the brands affected.
Investigations are underway after another strawberry contamination case has been reported in Townsville, in north Queensland.
It's unclear if Ms Faugeras' discovery is related to the earlier incidents or a potential copycat.

NSW Police are warning the contamination may have spread beyond the Berry Obsession, Berry Licious and Donnybrook brands confirmed by Queensland Police.
Police are also investigating a copycat saboteur after a Coles employee at a Gatton store, about 90 kilometres west of Brisbane, found a "small silver rod" on top of strawberries in a punnet.
A mother of three in Gladstone also found two needles in a punnet while cutting up the fruit. It was treated as a copycat incident.
Authorities said that the contaminated strawberries-branded Berrylicious and Berry Obsession-came from two farms located next to each other in south-east Queensland.
"People are contacting us out of concern and saying: 'This is what I've got, what do you think?'", he said.
They are sold at Woolworths and possibly other outlets.
The Queensland Strawberry Growers Association believes a disgruntled farm worker may be responsible but police say they are investigating all aspects of the strawberry transit process.
Police were investigating the possibility of an extortion attempt or someone carrying out a vendetta against the supermarket giant.
"As with all farmers who produce food for our nation, strawberry growers strive to ensure the quality, security and freshness of their produce and these spiteful incidents have been extremely disheartening and troubling", the association wrote in a statement. "We're not agreeing with that at all at this particular point in time; our investigation is still open", he said.
"We're not going to speculate at this stage".
