    Keep food safe        Food poisoning, with its symptoms of vomiting,
                          diarrhoea and stomach cramps, is a very unpleasant
                          illness from which most of us will recover.
                          However, for some people, including young
                          children and the frail elderly, it can be life threaten-

                          One cause of food poisoning is bacteria that have
                          had the opportunity to multiply in food.

                          Bacteria that have the chance to multiply in food
                          cause food poisoning in two ways. They either
                          multiply in foods to sufficient numbers to make us
                          ill or, as they multiply, they produce poisons in the
                          food that cause illness.
