The World: Boston - Tyson Foods has 14 days to recall 'misleading' ads

A US federal appeals court has rejected an appeal by a food company against an order to remove misleading advertising.

A judge in Richmond, Virginia, gave Tyson Foods 14 days' notice to remove ads from 8,500 stores that claimed its chickens were safer to eat because they were raised without antibiotics.

Created by Arnold in Boston, the ads sparked legal action by Tyson's rivals. They claimed the ads were misleading as none of the companies used such drugs.
