Does McDonald\'s contain preservatives?
Joann Bruso, 62, a U.S. nutritionist, said McDonald\'s hamburgers contain high amounts of preservatives. She said her claims were based on an experiment at home.
Bruso said she bought a meal from McDonald\'s a year ago that failed to decompose even after a year, the Daily Mail reported.
A picture of the hamburger and French fries, which she posted on her blog, appeared not be drying up and the bun was just dried and cracked.
