1. Campylobacter is the most commonly identified cause of food-borne disease. It has been found mainly in poultry, red meat, unpasteurised milk and untreated water. Although it doesn't grow in food it spreads easily, so only a few bacteria in a piece of chicken could cause illness.
2. Salmonella is the second most common cause of food poisoning. It has been found in unpasteurised milk, eggs and raw egg products, meat and poultry. It can survive if food is not cooked properly.
3. E.coli short for Escherichia coli - is typically transmitted through undercooked minced beef or milk that is raw, inadequately pasteurised or contaminated after pasteurisation. Most strains of E.coli are harmless, but
there have been fatal outbreaks in recent years. An outbreak in Scotland in 1996 killed 17 elderly people and made another 500 seriously ill after eating contaminated meat products from a butcher's shop.
