There has been an increase in campylobacteriosis case notifications in the last four weeks in the Nelson Marlborough region.

24 cases have been notified to the Medical Officer of Health in the past four weeks, compared to a range of 6-16 cases in the same period over the previous five years.

Nelson Marlborough Health is working with the Ministry for Primary Industries, the Ministry of Health and the Institute of Environmental Science and Research to try and identify the reasons for the increase.

A number of known risk factors for campylobacteriosis have been identified in the people affected. These are: drinking raw (unpasteurised) milk or untreated water, and contact with animals and/or nappies.

A single source cause has yet to be found and investigations are ongoing.

About campylobacteriosis

Campylobacteriosis is a common water and food-borne gastro-intestinal disease caused by bacteria passed on in the faeces of infected birds, animals and humans. People who are immunocompromised, elderly or very young are at higher risk of severe disease, which rarely can be fatal. Campylobacteriosis can be contracted through:

-consuming raw milk

-consuming uncooked poultry

-consuming untreated drinking water

-contact with infected pets and farm animals

-contact with nappies of infected infants
