Campylobacter causes severe diarrhoea, nausea, vomiting and fever. It is found on raw or undercooked meat (particularly poultry), unpasteurised milk and untreated water. The illness can also be passed on by animals, pets and birds. Symptoms usually appear 2 to 5 days after eating contaminated food and usually last up to a week.
E.coli causes severe stomach cramps, vomiting and diarrhoea. It is found in the digestive system of many animals and humans. Most cases of E. coli food poisoning occur after eating undercooked beef (particularly mince, burgers and meatballs) or drinking unpasteurised milk.

Shigella causes severe diarrhoea, nausea, vomiting, fever and often blood or mucus in the stool. It is found in any food that has been washed in contaminated water.

Dysentery is a disease which causes severe diarrhoea, nausea, vomiting and high fever.

Symptoms usually appear after 1 to 3 days and usually last up to a week.
