One Queenslander and two Victorians have reported discovering sewing needles in their strawberries, and police believe the contamination is deliberate.

It has prompted an urgent supermarket recall and a health warning across Queensland, Victoria and NSW after the needles were found in punnets of strawberries from a south-east Queensland farm.

The two brands involved are Berry Licious and Berry Obsession, which were supplied to Woolworths and other stores.

The Queensland man who reported the contamination on Sunday was the only person known to have consumed the fruit with needles inside and was being assessed by doctors.

In a Facebook post, Joshua Gane said his friend swallowed "half a sewing needle" after biting into a strawberry.

"We then checked the other strawberries and found another sewing needle lodged inside one of them. We are now at the ER because he subsequently started experiencing severe abdominal pain.

"Just being a helpful member of the community and making sure your children don’t have to endure what we have had to experience today. Please make your family and friends aware."

Two more cases in Victoria reported the contamination on Tuesday night, but had not eaten the strawberries. Victoria Police said the punnets were found in Yarram and Ballarat.

Queensland’s chief health officer Dr Jeannette Young said the products had been recalled on Wednesday to ensure any potentially contaminated strawberries were removed, but would be back on shelves on Thursday.

"I'm out here today to advise people that if they have bought strawberries in Queensland, NSW or Victoria since early last week that they should dispose of them," Dr Young said.

"Definitely those two are the only brands of concern, but if people don't know and they want to be ultra-cautious then it would be best if they just throw out any strawberries they've kept."

Dr Young said the two brands of strawberries came from the same south-east Queensland farm and particularly warned those who had stored strawberries in the fridge or freezer to check the brand.

There could be serious health risks, because the needles could get caught in the gut.

Anyone who believes they may have swallowed contaminated strawberries should call 13 HEALTH (13 43 25 84) or see their local doctor.

Queensland Strawberry Growers Association industry development officer Jennifer Rowling claimed a "disgruntled ex-employee" may be responsible for the contamination.

"At this time, the Queensland Strawberry Growers Association have reason to suspect that a disgruntled ex-employee may have orchestrated the occurrence, wherein sewing needles were found in a number of strawberries, in Queensland and Victoria," Ms Rowling said in a statement.

"The Queensland Strawberry Growers Association is waiting on more information from Queensland Police on this matter and will update the Australian public as news becomes available to us."

The Queensland Police Service declined to comment on the claim.

Detective Superintendent Terry Lawrence said those responsible for contaminating the fruit could be charged with maliciously causing grievous bodily harm.

"We're fairly confident that if people do come forward with a needle in a strawberry and in particular the packaging, that will provide us with some direction," he said.

"It's been some time for us to look at this sort of investigation."

The farm owner and employees were assisting police with their inquiries.
