'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,' the statement read.
'To our current knowledge, two labels, Berry Licious and Berry Obsession are the only affected lines.
'We will update the Australian public as news becomes available to us.'
Joshua Gane was one of the many who found a needle in his strawberries.
Driving with a friend,Haoni van Dorp, the two purchased a punnet of strawberries on Sunday afternoon.
Van Dorp says he bit into one and swallowed half of a sewing needle, before the pair found another.
Police believe the needles may have been deliberately planted with the perpetrator wanting to cause harm.
Gane posted the ordeal to Facebook, along with a picture that shows a metal pin poking out of a strawberry.
Van Dorp had to be taken to the emergency room with 'severe abdominal pain.'
Queensland's Chief Health Officer Dr Jeannette Young said anyone else who had bought the brands of strawberries without signs of tampering should return them to the store or throw them away.
'While it is expected that berries picked early last week would now not be useable, many people freeze the fruit for later use,' she said.
'If you are in doubt, just throw them out.'
Dr Young said that any strawberries bought from September 13 are safe.
'Any strawberries that you are certain are not the brands Berry Licious and Berry Obsession, are safe,' she confirmed.
'If you believe you have eaten a needle, we would recommend you speak to your doctor or call 13 HEALTH.
'There is no reason to stop eating strawberries, we just need to be aware of this incident.'
