Fast food these days are not how it used to be. These days, they contain so many chemicals that even 15 years, this McDonald’s hamburger from 1999 never aged. McDonald’s employees report that McDonalds uses expired meat. When the food inspector comes, they just remove the label and put a new one on. Meat Suppliers were just recently shut down in China when video footage of this was released to the public. There are also reports that McDonalds uses chicken fillers. There are not many fast-food restaurants that still use fresh ingredients. To name a few, Panera Bread and Five Guys still do. The fast food industry has changed a lot since the first McDonalds and KFC’s.
