We have been investigating if it really is important to wash our hands before touching food. Do we have bacteria and germs on our hands?
After playtime we all touched a piece of bread without washing our hands.
We then washed our hands with soap and water and then all touched another piece of bread.
We also had a piece of bread that no one touched.
Below are the results after we left them in a sealed plastic bag for a week!
The bread touched with dirty hands developed the most mould, caused by bacteria.
The bread touched with clean hands also developed spots of mould all over but not as much.
The bread not touched by hands, also developed a little mould but it was not as spread as the 'clean hands' bread.
Conclusion. Our hands do carry bacteria and it is important to wash them before handling or eating food!
