4-year-old 'fresh' cheeseburger becomes YouTube sensation!

London, Sept 1 (ANI): A video of a four-year-old McDonald's burger still not gone bad has become an instant hit on the internet.

Diet writer Julia Havey has posted the video footage of the cheeseburger, which does not have a single speck of mould on it, on YouTube.

The Daily Star quoted nutritional therapist Catherine Andrews, as saying: "It does make you wonder what they are putting in these things."

The burger was kept intact for four years in a lunchbox. (ANI)
