A former McDonald's chef has revealed just how long it takes for one of the chain's burgers to go mouldy. Mike Haracz, known as @chefmikeharacz on TikTok, says he used to work in McDonald's corporate office – and has been sharing 'insider information' about the business on social media. After customers started to question what's actually in McDonald's food, he settled the debate on whether its produce ever 'goes off'.

It comes after YouTuber DebunkerSam's video showing 'The decomposition of McDonald's burgers and fries' resurfaced online after being originally uploaded 13 years ago. In the five-minute video, he puts its fries and burgers into jars and documents how long it takes for them to decompose. After two weeks, its fries look almost identical from the day he bought them while its quarter pounder burger, chicken burger, and fish burger all start showing signs of mould.

However, he claims the Big Mac remains the same as when he put it in the jar, saying "it hasn't even started to mould yet". After three weeks, the lettuce in the meal starts to go mouldy but the rest of the burger appears to remain the same. By week five, the Big Mac is completely covered in mould alongside the other burgers.

But once again, the fries remain intact. Recording his last video 10 weeks in, and speaking about the French fries, he says: "Look at that! What is wrong with that? there's not even one spore on there, it's not breaking down – nothing. It looks like we bought them yesterday.
