More than 100,000 mangoes from a Queensland supplier have been recalled after fruit fly larvae was found in a mango in the Adelaide foothills.
Biosecurity SA issued the recall when a person in the suburb of Hawthorndene reported finding larvae.
At this time of year, mangoes are supplied to South Australia from the Northern Territory and Queensland.
Biosecurity SA's Will Zacharin said the detection did not constitute an outbreak of fruit fly and stressed the situation was being closely monitored.
"Obviously there has been a problem in this case and we will be working with the Queensland Government and authorities to rectify that to make sure it can't happen again," he said.
"But from time to time you know, it can happen."
Mr Zacharin said people should call the fruit fly hotline on 1300 666 010 if they find anything suspicious.
"They are very small white larvae, smaller than a blowfly larvae ... and they will be quite obvious to you when you cut the fruit open," he said.
"If they are there you will see them moving around under the fruit material under the skin."
Mr Zacharin said affected fruit should not be thrown into a bin or compost and should not be returned to where it was purchased from.
"Bag it up into a sealed plastic bag, ring the hotline and we will come and pick it up because we need to try and trace every infected mango that may have come into the state [South Australia]," Mr Zacharin said.
