1. Keeping the cooked food covered
2. Developing the habit of cleanliness
3. Not walking barefooted

Cleanliness helps in maintaining personal hygiene and clean surroundings whicch is vital for curbing infections and promoting good health
Many fungi and virus can enter via our feet if we walk barefoot
Hair and the scalp remain healthy when washed and combed regularly as it improves blood circulation and does not let dirt accumulate
Hands should be washed before every meal so that germs are not transferred from hands to our body while eating
