A $100,000 reward has been posted to catch Queensland’s strawberry spiker, as the food sabotage scandal continues to spread.

Premier Annastacia Palaszczuk stumped up the reward for information leading to the capture of those spiking strawberries with needles.

The reward came as the tampering spread, with up to six brands now affected nationwide.

Police have been investigating this week after sewing needles were found in strawberries sold in Victoria and Queensland but the crisis has now spread to NSW, ACT and South Australia.

It is now believed the contamination may affect six brands of strawberries: “Berry Obsession”, “Berry Licious”, “Love Berry”, “Donnybrook Berries”, “Delightful Strawberries”, and “Oasis”.

These brands are believed to be sold in stores in NSW, Queensland, Victoria, and the Australian Capital Territory.

So far NSW Police Force has received reports of contaminated strawberries purchased at supermarkets at Tweed Heads, Taree, and Wingham.

It follows reports of contaminated strawberries in Queensland and Victoria.

It’s unclear whether the NSW strawberries originated from a Queensland-based supplier that is at the centre of the scare, or if they are copycat incidents.

Police are urging shoppers to cut up strawberries before eating them.

“They are not only endangering people’s lives, they are threatening an entire industry,” the Premier told The Courier-Mail.

“We’re not going to stand for it. We have to come together.”

The reward came as the tampering spread, with up to six brands now affected nationwide.

NSW mother Chantal Faugeras posted to Facebook about her young child finding needles in strawberries bought at Coles on Tuesday.

Queensland Health is yet to recall the brand, saying it is assessing reports as they come in.

“When we get three (reports), it suggests there’s something going on that we then need to withdraw that entire product,” Dr Young said.

Acting Chief Superintendent Terry Lawrence said the investigation was complex, and he wouldn’t comment on whether police had any suspects.
