7. Preservation: After cooking a food, if you are not eating it at that moment then cool it quickly and put it in the refrigerator. Actually keeping it in room temperature for a long time can lead to bacterial attack. And also if the food is not covered properly, insects can get into contact with that. So don’t keep your food uncovered outside.
8. Keep your pets away: If your food is kept outside, then keep away your pets from the food. Pet animals can have a taste of your food. And this is the real cause so that you should keep them away. Actually the pets may contain bacteria in their saliva that is very dangerous for humans.
