Eating at fast food outlets may be a delight for the taste buds, but junk food isn’t exactly known for being healthy. Recently fast food chains like McDonald’s and Burger King came under fire for faecal material in ice, and now it seems McDonald’s may be in trouble again.

A former employee of the burger giant posted pictures on Twitter showing greasy pictures of a meal tray, claiming that it came out of an ice cream machine at an outlet he worked at.

His tweets created a buzz on social media as people were shocked by the revelation about the truth behind the ice creams they were consuming.

The employee also tweeted saying that he planned the expose as he was fired from McDonald’s and is already slated to join a new job.
