Rural communities warned to be on alert for illness caused by toxin producing bacteria
Taranaki’s rural communities are being warned to be on alert for illness caused by bacteria carried in the intestines of
cattle and other animals which can cause severe gastroenteritis in young children.
Taranaki DHB’s Medical Officer of Health, Dr Jonathan Jarman says “Taranaki has high rates of Shiga toxin producing
E.coli (STEC), also known as Verotoxin producing E.coli (VTEC). Young children on farms with cattle are at high risk of
catching this disease, with nearly half of cases ending up in hospital.”
August through to October is the peak season for STEC/VTEC, with the main symptoms being watery diarrhoea, blood in the
diarrhoea, severe stomach pains and vomiting.
Other risk factors include drinking unpasteurised milk or untreated water, eating undercooked or contaminated food,
swimming in water where you can’t see your feet and being in contact with people who have the infection.
Dr Jarman says “Young children with STEC illness are more likely to get a severe complication called Haemolytic Uraemic
Syndrome (HUS) which could damage their kidneys. On average we get a child with this complication once a year in
Taranaki.
We’ve already had one case in April where a very sick child ended up needing further treatment in Auckland.”
Dr Jarman says that the main source for these toxin producing bacteria was animal waste, but can also be found in places
contaminated with animal waste such as muddy puddles near farm animals or animals drinking troughs, farm clothing and
footwear, and in dogs and other farm animals going inside a house.
“Children under five living on or visiting farms with cattle and calves are most at risk from STEC illness. Anyone
showing signs of the STEC infection should seek advice from their doctor or by calling Healthline on 0800 611 116 before
taking any medication for this illness as some may even make it worse,” he says.
One of the best ways to prevent infection is regular hand washing before eating, after helping out on a farm and after
touching animals. Other ways to prevent infection include cooking meat thoroughly to kill any STEC bacteria and boiling
untreated water and raw milk before drinking it.
