Food poisoning cases are on the increase. Nearly 7300 cases of campylobactor were reported to health agencies up until November this year.
That is up from the same time last year, when nearly 1000 fewer campylobactor cases were reported.
Campylobactor cases have more than doubled in the Nelson Marlborough region, in the three months from the begining of September. Reasons for the rise are not clear.
Medical Officer of Health Jill Sherwood said there are no obvious links between the cases and suggests that a number of factors may be involved.
Dr Sherwood said those factors include runoff from increased rainfall contaminating surface or well water and people not taking enough care with food preparation.
