Storing food

People say that storing food in refrigerator is good because it can last longer as there will be no bacteria etc. But the truth is Bacteria is OMNI-PRESENT. It's just the cold temperature in refrigerator effects the low-hormone functions, digestive rate, growth rate... that ultimately help in storing the food for longer period. At room temperature (around 35C) the bacteria's activity is high. Thats why in summer food gets spoiled early.
