Strawberries with needles allegedly found in Tasmania in the middle of a police investigation

Strawberry punnets at a supermarket in Sydney.

The search for culprits by inserting needles into strawberries is spreading after more contaminated fruit cartons were found in New South Wales and South Australia.

It is feared that the imitators are behind the latest discoveries within the supermarket strawberries, and consumers were warned to continue cutting any fruit that is not on the recall list before eating it.

Numerous needles and pins have been found in the fruit throughout the country, prompting the federal government to announce that it is examining the management of the problem by the states.

The last contaminated lot was detected in Woodville, outside of Newcastle NSW.

The Wallace Road Strawberry Basket was purchased from Coles at the nearby Stockland Greenhills Mall, NSW police told AAP on Sunday.

Authorities expect that a reward of $ 100,000 for information provided by the Queensland government will lead to the capture of the perpetrator or the perpetrators.

The NSW detectives will meet on Monday to share information as they work to discover the source of the contamination.

The sabotage spread to South Australia over the weekend, with a needle found in a basket of strawberries Mal & # 39; s Black Label on Sunday.

Tasmania police are also investigating possible contamination of a basket purchased at Woolworths in Hobart.

The discovery came when Coles and Aldi supermarkets pulled all the strawberries from their shelves throughout the country, except in Western Australia, as a precautionary measure.

Berry Obsession, Berry Licious and Donnybrook Berries have removed their strawberries across the country.

The police are also investigating the contamination of the fruit sold by Delightful Strawberries, Love Berries and Oasis in stores in NSW, Queensland, Victoria and ACT.

Health Minister Greg Hunt ordered the national food safety watchdog to assess how states handle strawberry contamination.

"This is a very vicious crime and it is a general attack on the public, and it is also an attack on a specific industry," he told reporters on Sunday.

A health warning to throw or cut strawberries remains in Queensland, NSW, Victoria and South Australia.

"Remember, if you have any doubts, throw them away, otherwise be sure to cut before eating," said Jeanette Young, Queensland Health Director.
