Now the major supermarkets are following up with tests of their own.
Raspberries are a super cancer-fighting food, packed full of antioxidants, but tests have shown that banned chemicals in the imported frozen raspberries eradicate any health benefits.
In the last year more than 5000 tonnes of both frozen and processed raspberries have been imported into Australia from overseas.More stories from Today Tonight

Richard Clark runs the Westerway Raspberry Farm near Hobart in Tasmania. He can't compete with the cheap imports coming into Australia, and points out that most of the raspberries in jams, smoothie bars and juices are imported.
"I reckon most people who sit down to their breakfast and have raspberry jam on their toast, they'd be expecting most of those raspberries to be from Australia, but that's probably not the case," Clark said.
Go to any supermarket and every frozen raspberry packet you pick up will be imported - mainly from Chile or China - countries that don't have strict chemical regulations or stringent testing.
Once they get here, only five per cent of frozen foods are then tested by customs.
Ausveg CEO Richard Mulcahey is calling on the Federal Government to take the testing of imported foods seriously.
"If it was up to 25 per cent it would be a statistically strong enough base to know if there was serious issues in terms of imported food," Mulcahey said.
"I think the Government has got a responsibility to ensure the food coming into the supermarkets and onto our shelves is safe for human consumption."
In the tests conducted by Today Tonight, six bags of frozen raspberries were sent to a NATA-accredited lab to be tested for 230 different chemicals. Of the six, two recorded violations of our regulations.
According to Jo Immig, coordinator for the National Toxics Network "if (the chemicals) are coming in on imported raspberries we should be concerned ... why do we have berries coming into the country with fungicides that are we don't use in Australia on those same products?"
While the results fell under our levels considered safe, they are both hormone disrupters.
"These are chemicals that can have impacts on the body in the parts per billion. And the carbaryl is a likely carcinogen - these are not the sorts of chemicals we want to be eating every time we sit down to a bowl of berries," Immig said.Response statements
