Salmonella is a bacterium which causes an infection of the bowel. In New Zealand outbreaks of the disease are common. Doctors are legally required to notify the Public Health Service of cases of salmonella disease under the Health Act 1956.
In the Nelson Marlborough district around 35 cases of salmonella disease are notified each year. The highest number of cases notified is in young children.
The disease may cause abdominal pains, diarrhoea, fever, nausea (a feeling of sickness) and vomiting. People usually get sick 12–36 hours after ingesting (swallowing) the salmonella bacteria and these symptoms usually last for 3 – 5 days.
Contact your GP or Healthline (0800 611 116) for further advice.
