South Australia Police have today confirmed they are investigating a second claim of contaminated strawberries in Adelaide.

It has been alleged a metal object was found embedded in a strawberry purchased from the Adelaide Fresh Fruiterers shop at Main South Road, Morphett Vale in the city's south.

No one was injured.

The contaminated strawberry was found in a punnet of Mal's Black Label strawberries, grown in WA.

The same brand was implicated in SA's other contamination case.

Yesterday a seven-year-old girl bit into a strawberry containing a needle.

The punnet was purchased from an Adelaide Hills supermarket on Saturday.

Police said the incident on Saturday was reported by the child's father on Sunday evening and fortunately, the child was not injured.

Police say the punnet was also from Mal's Black Label strawberries, and was purchased on Saturday afternoon from Kloses's Foodland supermarket at Littlehampton.

When the fruit was eaten on Sunday morning, a needle was found inside one of the strawberries.

Police said there were no reported injuries, but all remaining stock has been removed from all the supermarket's locations.

"There was a complaint made to police yesterday evening in relation to a needle being found by a seven-year-old as she was eating some strawberries that were bought in Littlehampton on Saturday evening," Detective Inspector Billy Thompson said.

"She was having those on Sunday morning when she bit into one of the strawberries and discovered a needle, which she told her mum about and as a result of that the father took the strawberries to the store in Littlehampton, reported it to the manager who in turn advised the matter should be reported to police.

"We are investigating the circumstances around that."

Strong possibility of a 'copy cat'

Detective Inspector Thompson also said that the incident in South Australia could be the work of a "copy cat" following other incidents across the country.

"There is a strong possibility that people have an idea that it would be a good idea to copy cat this type of activity, we would strongly advise against that," he said.

"It is an offence to endanger someone else by doing such a thing.

"I also might add that some people may think that it's to take advantage of this situation and make a false report in relation to these matters, again we strongly advise against that.

"Anyone who makes a false report in these circumstances is liable to imprisonment for up to two years.

"If you do come across a needle in strawberries, definitely report it to police … and we will investigate it fully."

Dr Chris Lease, a spokesman for SA Health also used the opportunity to remind people to be vigilant when consuming strawberries.

"With the events unfolding across Australia and now more recently in South Australia about the deliberate contamination of strawberries with sewing needles we thought that it's important to remind people to take a bit of extra precaution and extra vigilance when consuming strawberries," he said.

"Making sure that they chop those before they do consume them."

Police said they were taking reports very seriously and those behind it would face "serious criminal offences".

Mal's Black Label Strawberries are grown and packaged in Gingin — 70 kilometres north of Perth.

A West Australian Department of Health spokesman said while there have been no reports of contaminated strawberries in WA, anyone who has purchased Mal's Black Label strawberries should cut them as a precaution.

"The Department is investigating further to see if this particular brand of strawberries is distributed in WA," he said.

This latest incident comes after several reports of strawberries contaminated by pins and needles up and down the east coast of Australia.

Before this case in South Australia, six brands of strawberries — Donnybrook Berries, Love Berry, Delightful Strawberries, Oasis brands, Berry Obsession and Berry Licious — had been affected.

On Saturday, the Queensland Government issued a $100,000 reward for any information that could lead to the arrest of the culprit.
