All food has bacteria all over it. When you wait too long to eat some food, food that isn't cooked properly or is left at room temperature too long after cooking, there's some extra stuff on the food. This is because the bacteria poop on the food.  When you eat bacteria poop,  the bacteria that breaks down food in your stomach tries to break down the poop and releases gas. A lot of it. The gas puts pressure on your stomach and intestines which can cause a lot of painful  tummy aches.
