Our Answer
McCain Foods make McDonald’s French fries to our gold standard specifications, which means that they are not quite the same McCain fries you find in the freezer section of your grocery store. Our cooking process is also different from how you might cook fries at home. The reason why our French fries don’t break down or decompose when left out at room temperature, is that once they are cooked, there is not enough moisture to support bacterial or mould growth.
