Fruit growers at Orange in New South Wales have been shocked by the discovery of counterfeit cherry boxes in China.

Recent storms and rainfall have increased the urgency for cherry growers to pick their fruit before the extra moisture causes any splitting or cracking.

Now another challenge has hit the group marketing its fruit under the BiteRiot brand, with a number of counterfeit BiteRiot boxes of cherries uncovered in China.

Caernarvon Cherry Company general manager Allan Bramble says the origin of the fruit is actually unknown.

"It's pretty easy to see the difference between ours and the counterfeit product," he said.

"People will exploit other people's success and that's quite complimentary in itself. It's a testament to the quality of the fruit that comes out if this region."

Mr Bramble says a customer alerted him to the scam.

"We're in the process of trying to find some contact details and narrow down exactly who's supplying that produce and selling it and we'll be taking every avenue we can to pursue and obviously stop the practice from occurring again," he said.

The small volume of the counterfeit haul leads Mr Bramble to believe it was an opportunistic attempt to cash in on the renowned Australian brand.

"I think it's someone that's seen the BiteRiot brand top the China market a couple of times last year and they've just obviously taken advantage of that."
