Answer 1

Health is basically the state of a person well being physically as well as mentally. We all might have seen exposed food being attacked by the animals that makes it unfit for consumption.

Complete answer: We know that health, for a long time, was considered as the state of body and mind where there was a balance of certain "humours. This is what early Greeks like Hippocrates as well as Indian Ayurveda system of medicine asserted.
Many diseases are caused due to consumption of exposed food. Flies are the insects that contaminate the exposed food and make it unfit for consumption. They do so because they transfer germs from one surface to another.
Flies play a major role as a vector in transmitting various bacteria and pose bacterial contamination risks in the food. They are born in the areas where there is a lot of garbage, faeces and rotting matter. These waste contains harmful bacteria that are on their surfaces. When these flies land on these wastes, they carry with them the germs. The 6 jointed legs of the housefly thus contaminates the food that is kept open.
That is why it is advised to not to keep food open and we should not consume food that is kept open. Safety is in our hands. To prevent yourself from these issues one should always be alert and aware.
One should keep their food covered.
Keep your surrounding clean
Try to avoid stagnant water around your place as it is the breeding place for them.
One should not litter around in public places.

Note: Flies are the insects whose name has been derived from Greek di "two"and pteron "wing". Insects of this order use only a single pair of wings to fly. They have a mobile head and a pair of large compound eyes, and mouthparts designed for piercing and sucking.
