Ridley Corporation to close Murray Bridge feed mill

Almost 100 years to the day after it opened, Ridley Agriproducts has announced it will close its Murray Bridge mill.

Staff were told of the company's decision this morning, and "wherever possible" had been offered work at other Ridley sites, the company said in a statement.

While the decision was "disappointing", chief executive officer Quinton Hildebrand said, the mill had been losing about $1.5 million per year.

It was heavily impacted by the loss of an Ingham's supply contract last year, after the chicken company opened its own feed mill at Brinkley.

Thirteen employees lost their jobs at that time as the Ridley mill moved to a single shift.

Growers who deliver their grain to the Murray Bridge mill will be asked to send it to Ridley's Wasleys mill, north of Gawler, from October 25.

The mill originally opened on September 30, 1919.

It was subsequently gutted by fire in 1920 but has operated continuously ever since.
