Harmful microorganisms

Microorganisms that cause diseases are often called germs.
Some diseases, like chickenpox, are caused by viruses. Diseases caused by viruses usually spread easily from one person to another.
Uncooked foods (especially meat) can contain bacteria. The bacteria are killed when the food is cooked properly. But if you eat food that has not been cooked properly, the bacteria may survive and make you feel very ill.

Mould is a type of microorganism that grows on decaying food. It can make you ill if you eat it.

How to avoid spreading harmful microorganisms

You can avoid spreading harmful microorganisms by:
  • washing your hands before eating, after preparing food and after using the toilet.
  • covering your mouth when you cough or sneeze.
  • keeping away from other people if you have a disease that is easily spread.
  • not eating food which is not fresh or has not been cooked properly.
  • keeping uncooked meat separate from other foods in the fridge.
