What is Bacteria?
Bactria is a  member of a large group of unicellular microorganisms which have cell walls but lack organelles and an organised nucleus, including some which can cause disease.

What does Bacteria need to survive?
Bacteria need water to dissolve the food they use for energy and growth. Energy sources such as sugars, starch, protein, fats and other compounds provide the nutrients Some bacteria require oxygen to grow (aerobes) while others can grow only in the absence of oxygen (anaerobes).

What are three examples of how to not spread bacteria?
Some examples of 'vehicles' are our hands, insects, droplets in the air, wind-blown dust, water and blood, which carries germs around the body. If germs can get into the body they can make a person very sick. Below are some of the methods by which 'vehicles' can help spread germs to people.

What does the term cross contaminated mean and what is its effect on us?
Cross-contamination is a cause of food poisoning that is often overlooked. It occurs when harmful bacteria are spread between food, surfaces and equipment. Cross-contamination can also occur if raw meat is stored above ready-to-eat meals. If juices from the meat drip on to the food below, it can contaminate it, and this can lead to food poisoning.
