A Deadly Soil-Borne Threat: Melioidosis Warnings in North Queensland
The recent heavy rainfall and subsequent flooding in North Queensland have led to a concerning rise in melioidosis cases, with four individuals hospitalized and a broader public health concern emerging.
In the small community of Armstrong Beach, Mackay, and the surrounding regions, including Seaforth and Bowen, four elderly individuals, aged between 67 and 89, have fallen ill with this potentially fatal soil-borne illness. All of them had been exposed to mud or floodwaters during the clean-up efforts.
As of January 19, Queensland has confirmed 16 cases across various regions, with a notable cluster in the Mackay area. This has prompted a timely warning from Steven Donohue, the director of the Mackay Public Health Unit, especially for those still engaged in the clean-up after ex-Tropical Cyclone Koji.
"The bacteria can enter the body through a simple skin break or by inhaling muddy droplets," Dr. Donohue explained. He emphasized that those most vulnerable to melioidosis are already unwell, elderly, or have underlying health conditions like diabetes or kidney disease.
The statistics are alarming: from January to November 2025, 36 people lost their lives to this illness, a significant increase from the nine fatalities in 2022 due to both melioidosis and the bacterial disease glanders.
However, Dr. Donohue assures that early diagnosis and prompt treatment with antibiotics can be life-saving. "It's a serious illness, but we don't want to cause unnecessary panic," he added.
But here's where it gets controversial...
Queensland Health has launched a public health campaign, and investigations are underway to determine the cause of the 2025 outbreak. Dr. Michael Clements, the Rural Chair of the Royal Australian College of General Practitioners, highlights the increased risk during post-flood clean-up activities.
"A week of heavy rain has brought the bacteria to the surface, and activities like pressure washing, spraying, or even mowing the lawn can aerosolize these bacteria, posing a risk if inhaled," Dr. Clements warned. He recommends that those involved in clean-up efforts cover their legs or wear masks, depending on the task, to minimize exposure.
"Melioidosis can present late and be deadly. We must take it seriously and take the necessary precautions," he emphasized.
And this is the part most people miss...
While the focus is on the current outbreak, it's essential to understand the long-term implications. Melioidosis can lie dormant for years, and with the increased exposure due to flooding, the potential for future cases is a concern. This highlights the need for ongoing public health education and awareness, especially in regions prone to flooding.
