Waitrose is extending the range of fruit covered by its Foundation ethical trading scheme, which helps South African workers.

The scheme, which began in June 2005, has raised £600,000 for its growers and pickers of South African citrus, grapes and avocados. Waitrose will add stone fruit by mid-December, and plums and grapes shortly after.Fruit carries a Waitrose Foundation sticker.

The first two projects kicked off last April to provide improved education facilities and allow farm workers to acquire new skills that would provide work opportunities outside the main fruit season.

"The extension of the scheme to stone fruit and grapes builds on the success we've had with citrus," Waitrose central fruit buyer Rupert Thomas told the in-house Gazette. "A little money goes a long way in South Africa. However, we are not going to change anything overnight, and are in this for the long term."
