Before you take your next bite of that McDonalds burger and fries you might want to take a look at these photos.
It would appear that Oak Brook-based McDonalds makes an indestructible product.
Davies checked on the food roughly every three days and took a picture each time. Judging from her images, Day One and Day 137 aren't that different. Wonder if she did a taste test?

Food scientists say it's two things: fat, and salt.
The more fat a product contains the less moisture it absorbs, and the less likely the food is to decay because elements like mold have trouble growing. Fifty percent of the calories in McDonald's burgers and fries come from fat.
Salt also prohibits moisture, and the Happy Meal has plenty to spare. One Mickey D's happy meal provides around half the daily recommended intake of sodium for an adult.
