Key Points
Two Melbourne toddlers hospitalised with kidney failure after petting farm visit, one with permanent brain damage.
Victoria records 160+ STEC cases in 2026, tracking toward 235 cases if trends continue.
Bacteria spreads through contact with animal faeces and causes vomiting, fever, bloody diarrhoea.
Health authorities advise handwashing after farm contact and warn symptoms can mimic standard gastro.
Two toddlers in Melbourne have been hospitalised with severe kidney failure after visiting the same petting farm, with one three-year-old suffering permanent brain damage. The incident has triggered an investigation by Victoria’s Department of Health into a spike of Shiga toxin-producing E. coli (STEC) infections across the state, which has recorded more than 160 cases this year compared to 156 in 2023.
What happened at the petting farm
A two-year-old boy and a three-year-old girl visited the same Melbourne petting farm and contracted a rare bacterial infection called haemolytic uraemic syndrome (HUS), caused by STEC. The two-year-old spent three weeks in intensive care, including 17 days on dialysis. The three-year-old spent four weeks in intensive care at Monash Children’s Hospital and has suffered permanent brain damage that will affect her for life. Her kidneys may not have fully recovered and she may need a kidney transplant.
How the bacteria spreads
STEC bacteria live in the guts of farm animals and spread to humans through contact with animal faeces. Early symptoms include vomiting, fever, and bloody diarrhoea, which can resemble standard gastroenteritis. Dr Nick Larkins from Perth Children’s Hospital told 9News that beyond standard hygiene measures, there is no way to prevent this entirely. The bacteria is believed to be present at most farms.
Victoria’s rising STEC outbreak
Victoria has recorded more than 160 cases of STEC this year, compared with 156 cases for all of 2023. If current trends continue, the state’s figures will eclipse the 235 cases recorded in 2024. The Department of Health is investigating the two cases linked to the petting farm. Health authorities have advised the farm to increase handwashing stations and display warning signs at its entrance about infection risks.
Advice for families visiting farms
Visitors to petting farms have been advised not to bring dummies, toys, or prams into animal pens. Health experts emphasise handwashing as critical after animal contact. The farm owner says they have met all health requirements and has posted additional warnings about animal-borne disease risks in response to the incident.
Final Thoughts
The outbreak underscores the hidden risks of petting farm visits for young children, even when facilities meet hygiene standards. Parents should ensure thorough handwashing after animal contact and watch for unusual gastro symptoms in the days following a farm visit.
