Three customers of The Grove Shopping Centre’s Woolworths store have reported finding that their food had been contaminated with needles and metal thumb tacks.
The Advertiser reports that metal needles were found in a punnet of strawberries and an avocado, with thumb tacks discovered in a loaf of bread.
The incidents took place between June 27 and July 1 at the Golden Grove store.
Woolworths staff investigated all stock linked to the incidents finding no further concerns for public safety.
South Australia Police are investigating what appears to be a deliberate act of contamination.
Similar incidents of strawberries being contaminated with sewing needles were widely reported across Australia in 2018, which led to tonnes of produce being dumped out of fear for public safety.
One woman recently faced charges for the initial contamination which reportedly led to over 240 copycat incidents across the country.
