Oreo cookies have come under fire after a controversial advert featuring a breastfeeding baby with the slogan; ‘Milk’s Favourite Cookie’ was leaked online.

The Cheil Worldwide Agency, a South Korean advertising agency, created the provocative advert, including an image of an Asian baby suckling on a fully exposed breast and nipple.

The leaked advert has created quite a stir on Twitter. See a round-up of the mixed reactions below:

In response to the uproar, the creators have come forward, claiming the advert was never intended to reach the public domain...

A representative from Kraft Foods, owner of Nabisco which produce Oreos, claim that the ad was created for a one-time use at an advertising forum and was not intended to go public.

The food company released a statement saying: “Our understanding is that they created it for use at an isolated advertising awards forum in Korea. It was never intended for consumer advertising or public distribution.”
