Bacterial contamination

Bacterial contamination. Conceptual computerartwork of a human hand contaminated with coloniesof bacteria (blue/pink patches). The lurid coloursrepresent the danger posed by the bacteria. Handscome into contact with a wide variety of surfaces, and can transmit bacteria to and between the eyes, nose and mouth. Common sources of particularlypathogenic bacteria are raw meat and faeces. Handwashing with soap and water can prevent most casesof disease transmission by hand contamination. Ifhands are not washed, the bacteria will quicklymultiply into colonies many millions strong..
