If you've ever wondered how much the farmer gets for the fruit you're holding in your hand, orange growers want to tell you this summer they're getting very little or nothing at all.

A survey of the supply chain for six fresh foods found that shops get as high as a 76 per cent share of the final price while growers, especially of oranges and apples, feel the squeeze.

Valencia orange grower Tania Chapman said she is getting 25¢ per kilogram, which barely cover her rising production costs. Others are getting as low as 17¢/kg and losing money.

"We're doing it tough. The cost of production is going through the roof, with fertilisers, with fuel, but our returns are going backwards," she said.
