A popular supermarket has pulled strawberries from its shelves after a customer found a needle in the fruit.

Anne Lentakis had purchased the punnet of Berry Indulgence from a Foodland in Stirling, Adelaide Hills, on Thursday.

Ms Lentakis told ABC Radio she and her 11-year-old son had been cutting the fruit for an afternoon snack when they came across the contaminated strawberry.
'He cut one strawberry and found a pin deep inside the strawberry,' she said.

'He said to me, 'Mum, I think there's a pin in my strawberry'.'

The distraught mother said her eight-year-old son later found another needle planted in a different strawberry.
Ms Lentakis has since notified the fruit and vegetable store of the find and it has pulled the Berry Indulgence brand from its shelves.

'I think there have been things put in place since this happened before with metal scanning, so that was a bit confusing to wonder how and why this could happen but [he was] very appreciative that I had called him,' she said.
'He had jumped on the phone and activated their procedures.'

South Australia police are reportedly investigating the incident.

The harrowing find comes after several needles and thumbtacks were found in groceries at South Australian supermarkets in June and July.

A metal needle was found in a punnet of strawberries and avocado and a thumbtack discovered in a loaf of bread after three different customers purchased the groceries from a Woolworths at Golden Grove, in north-Adelaide.

Woolworths provided police with CCTV footage and also launched their own investigation.
We've also commenced our own investigation with the assistance of our suppliers, in line with our established food safety procedures,' a supermarket spokesperson said at the time.
