Kraft foods has said that its ad featuring a breastfeeding child holding an Oreo, with the headline 'Milks Favourite Cookie' was not supposed to go public, and was online meant to be used in an advertising forum.
The company has denied claims that the image has been widely used in ads in South Korea.
The ad was created by Cheil Worldwide.
A spokesperson for Kraft has said: “This ad was created by our agency for a one-time use at an advertising forum. It was never intended for public distribution or use with consumers.
“It has never run in Korea or any other markets.”
