Microbes are responsible for creating some of our most enjoyable food products-- such as cheese, bread, yogurt, and of course, beer. But other microbes-- such as salmonella, listeria, or E coli 0157-- can do us a great deal of harm. In the UK alone, there are more than 10 million cases of gastroenteritis each year-- a concoction of symptoms, such as nausea, vomiting, diarrhoea, and stomach pain-- caused by eating and drinking food contaminated by microbes. Since ancient times we have done our utmost to keep them out.
