摘要:The term ‘enteric diseases’ includes a multitude of conditions. In the public health context, it usually refers to infections (or intoxications) that are food- or waterborne, or otherwise transmitted by the faecal-oral route. Symptoms are usually non-specific – nausea, vomiting, diarrhoea, abdominal pain and fever in varying combinations – and unpleasant, rather than serious or life threatening. The importance of enteric infections lies mainly in their numbers. The results from The National Gastroenteritis Survey 2001–2002 estimated that 17.2 million cases of gastroenteritis occur annually in Australia, leading to 7 million courses of medication (including antibiotics), 6 million days of paid work lost, 3.7 million doctor visits and 0.5 million stool tests.1 A third of gastroenteritis cases (5.4 million each year) are due to foodborne infection. There are also approximately 6000 cases annually of other foodborne diseases in which gastrointestinal symptoms are not prominent, such as invasive listeriosis.2 Overall, foodborne diseases are responsible for approximately 18 000 hospital admissions and 120 deaths, and cost $1249 million, annually in Australia.3
