Food and clothing manufacturer Sara Lee has said that it is in settlement talks with the Department of Justice over Earthgrains bakery’s handling of ozone-depleting substances.

Sara Lee purchased Earthgrains, the US’ second biggest bakery, in August last year for around US$2.8bn. The bakery was merged into Sara Lee’s own bakery to form Sara Lee Bakery.

The investigation into Earthgrains was referred to the Department of Justice by the Environmental Protection Agency.
