A McDonald's customer was left "sickened" after she claims she found multiple piles of fly eggs inside her cheeseburger.
Georgia Poole, 18, from Birmingham, visited her local branch on September 6 where she opted for the saver menu item.
As she started driving back home, eagerly awaiting a bite, she claims to have heard a buzzing coming from the takeaway bag.
The veterinary nurse assistant opened up her double cheeseburger, where she allegedly spotted a fly – which prompted her to inspect the food further.
Seconds later, Ms Poole reportedly noticed "wriggling" eggs underneath the gherkin.
"I just keep thinking if I hadn't seen that fly, I would have eaten it," Ms Poole told NeedToKnow.Online.
"I am trying to get my head around the fact of how McDonald's have managed to wrap up an alive fly.
"I am sickened by the thought that I had eaten a Big Mac before taking out the double cheeseburger – it's such a stomach-turning surprise.
"I'm just utterly disgusted by this, it has left me in total shock," she said, adding that the experience has put her off all takeaway food indefinitely.
"I want to warn as many people as I can to check their food before they eat it."
Ms Poole has attempted to contact the local branch, but claims she's been unable to get through.
Since then, she's contacted McDonald's and the Food Standards Agency in a bid to escalate the complaint.
In the meantime, Ms Poole uploaded photos of her find onto Facebook, which has clocked up 1,800 comments and 2,500 shares – and left social media users horrified.
"Surprised you didn’t get charged for the extra topping," one person said.
"Villeeeeee," another person wrote.
"As Bear Grylls would say 'Free Protein'," added another, while others vowed to never eat McDonald's again.
"Hope you reported it to environmental health... That's disgusting," one person commented.
A spokesman for McDonald's apologised for Ms Poole's experience.
"Food safety is of the utmost importance to us and we place great emphasis on quality control, following rigorous standards to avoid any imperfections," a spokesperson said.
"We have carried out extensive investigations at the restaurant, including a third party expert, and no issues have been identified.
"We've asked the customer to return the item to allow us to continue investigations, but this request has been declined.
"Our customer services team will continue to liaise with the customer to help find a resolution.”
