McDonald's Corp released a statement saying it plans to end its 40-year relationship with HJ Heinz Co due to the appointment of Bernardo Hees, former top executive at Burger King Worldwide, Inc. Heinz declined to comment. The change will be more noticeable outside the US--in the states, only the Pittsburgh and Minneapolis markets still use Heinz brand ketchup in stores. The move could benefit Heinz rival Hunt's, owned by ConAgra Foods and Del Monte. Burger King says it will continue to use Heinz products.
