Bacteria are microscopic organisms that can not be seen by naked eye. They can survive everywhere like on skin, hairs and nails. Most of bacteria may not harmful for us. However
pathogenic bacteria having potential hazard on our health.

Pathogenic bacteria are harmful. Those threaten effects our health through increasing in numbers at warm and moist environment.

Bacteria are so small organisms that only 2000 of them could be seen as pinhead. At the appropriate environment, bacteria could increase in numbers, within 7 hours it might be steeply increase to 2 million and within 12 hours it might be increase to 1 billion.

Bacteria can increase in numbers very fast at room temperature. Therefore, you should put your prepared foods, for consuming at school, into fridges quickly. Do not leave them on the table.
