$ 100,000 offered to capture the saboteur of berries as six brands related to pollution

Consumers are being told to cut up strawberries to make sure they are safe to eat.

The fruit sold under the Berry Obsession, Berry Licious and Donnybrook brands has been affected, while the NSW police warns that fruits sold under the brands Love Berry, Delightful Strawberries and Oasis were inserted with needles by a possible imitator.

The premier of Queensland, Annastacia Palaszczuk, issued the reward for the concerns of producers and consumers.

Empty shelves, usually stocked with strawberry punnets, can be seen at a Coles Supermarket in Brisbane.

"As the products have not yet been examined in a forensic manner, it is unknown whether the contamination is related to the original Queensland incident or to an imitator," NSW police said in a statement late Friday.

The products sold under those labels have been removed from the shelves, but it is not clear how big the health problem has become with the baskets sold throughout Australia.

A health warning to throw or cut strawberries remains in Queensland, New South Wales, Victoria and South Australia, while authorities hunt down those responsible.

"We have to see this as a whole, it's a very, very broad picture and we can not speculate in any way, shape or form," interim Queensland superintendent Terry Lawrence told reporters on Friday.

He says there is no link between the contamination of the Donnybrook berry and the Berry Obsession and Berry Licious cases.

On Thursday, Queensland police announced they were also investigating a possible imitation incident after a metal bar was discovered on strawberries inside a plastic basket in Coles, Gatton.
