A Queensland woman was recently charged with inserting needles into strawberries, triggering a nationwide food-tampering crisis.

My Ut Trinh, 50, was charged with seven counts of contamination of goods with intent to cause economic loss after police identified her DNA on a needle found in a strawberry punnet in Victoria, news.com.au reported.

According to the report, prosecutors allege the former strawberry farm supervisor was seeking revenge over a workplace grievance when she contaminated the fruit.

A Brisbane Magistrates Court heard the accused allegedly told a co-worker, “If I hate anyone, I would put the needle in the strawberry and make them go bankrupt.”

Trinh was granted bail after her lawyer argued the case against her was circumstantial.

“There is no motive. There has been no suggestion why this would occur,” Mr Dore said.
