A man who claimed to work in McDonalds has shared stomach-churning photos of what he claims came out of one of the fast food chain's ice cream machines.
The man, who goes by the name of "Nick" on Twitter and lives in Louisiana, shared the gross photos on his page and they have quickly gone viral.
The image shows a metal tray that he claims came out of one of the chain's ice cream machines - and it appears to be full of green gunk.
Posting the snap to Twitter on July 14, he wrote: "This came out of McDonald's ice cream machine in case y'all were wondering...":.
His tweet has since had 14,000 retweets and thousands of comments.
He then added another tweet, writing: 'People keep quoting this and saying this is the reason it's always down when it works perfectly fine with this in it.'
People were quick to comment saying it must be the remnants of a grease trap, to which he responded: "This is the side of the ice cream machine! It's not from a grease trap."
He then shared photos of the grease trap itself, before sharing more photos of dirty machinery and floors.
He told his followers: "I got fired from McDonald's. I strategically planned this because I start working at my new job Friday. I planned on losing my job."
His tweets have amassed thousands of responses and retweets from social media users.
MailOnline has contacted McDonald's and is awaiting a response.
