Health authorities have cracked a disturbing case after identifying homemade food products contaminated with rat poison that sent five people to hospital in south-east Queensland. What started as a medical mystery has now centered on two seemingly innocent items circulating in Logan’s local community.
The culprits? A homemade capsicum and chilli paste, and a marinated eggplant dish containing the same paste.
Five Victims, One Dangerous Thread
Queensland Health confirmed on 23 October 2025 that three of the five hospitalized individuals consumed these unlabelled homemade products. Laboratory testing revealed the presence of brodifacoum, a powerful anticoagulant commonly found in commercial rat poison.
The victims, including one child, presented to three hospitals across Brisbane’s south:
- Queensland Children’s Hospital
- Logan Hospital
- Princess Alexandra Hospital
All patients are recovering and receiving vitamin K therapy, the standard treatment for brodifacoum poisoning. Symptoms ranged from minor bleeding to more severe complications requiring extended hospital stays.
Dr Catherine McDougall, Queensland’s Chief Health Officer, stressed the products were not widely distributed. “It is believed they are available only very locally in the Logan community,” she stated.

How Did Rat Poison End Up in Food?
The investigation remains active, with Queensland Police Service working alongside health authorities to trace the contamination source. Products were either purchased or gifted in the Logan area from mid-September 2025 onwards.
Early speculation pointed to contamination at a fast food outlet. However, the confirmed source proves more localized and troubling. These homemade products lack commercial packaging, labels, or safety oversight.
Health Minister Tim Nicholls acknowledged the complexity: “If someone’s done something wrong, then they will know about it, but if they’ve done something wrong, we have to prove it, and we have to make sure that we’ve got the evidence to do it.”
The investigation explores whether contamination was accidental or deliberate.
The Science Behind Brodifacoum Poisoning
Brodifacoum works by depleting vitamin K in the body, preventing blood from clotting properly. Even trace amounts can trigger severe internal bleeding.
Brodifacoum is a powerful anticoagulant
Common symptoms include:
- Bleeding gums
- Unexplained bruising
- Blood in urine or stools
- Prolonged nosebleeds
- Joint swelling
Professor Paul Griffin, Director of Infectious Diseases at Mater Health, warned symptoms can take “many days” to appear. Treatment involves high-dose vitamin K therapy extending over several weeks.
Queensland Health has not disclosed the exact amount of brodifacoum detected. Historical cases suggest significant contamination levels are required to cause poisoning, though individual sensitivity varies.
Urgent Community Warning
Authorities issued clear instructions for Logan residents:
If you have these products:
- Throw them in the bin immediately
- Do not dispose of them in gardens where pets might access them
- Do not attempt to consume them
If you experience unexplained bleeding:
- Visit your local GP or urgent care clinic
- Present to an emergency department
- Call 13 HEALTH (13 43 25) for advice
Dr McDougall emphasized: “We do not believe there is a widespread risk to the broader community however, we encourage people in the Logan area to be alert.”
No additional cases have emerged since the initial five patients were identified last week.
Broader Context: Queensland’s Rodent Problem
This incident unfolds against Queensland’s ongoing battle with rodent populations. Between January and April 2025, agricultural regions reported unusually high mouse numbers following a substantial winter crop harvest.
The increased rodent activity has driven heavier rodenticide use across rural and urban areas. Brodifacoum products are widely available in hardware stores and supermarkets, making proper storage and handling critical.
This isn’t Queensland’s first brush with food contamination concerns. Earlier this year, major retailers recalled salad products over E. coli contamination risks.
Investigation Continues
Queensland Police Service released photos of the contaminated products to aid public awareness. The images show dark-colored paste in small containers and marinated vegetables in what appears to be home packaging.
Authorities continue analyzing distribution channels and interviewing affected individuals. The goal: determining whether this represents isolated contamination or indicates broader food safety concerns in the region.
Health officials maintain surveillance across the Metro South Health region, monitoring for any new cases presenting with similar symptoms.
Food Safety Lessons
This case highlights risks associated with unregulated homemade food products. Unlike commercial manufacturers, home cooks lack quality control systems, ingredient tracing, or contamination detection protocols.
Food safety experts recommend:
- Only accepting homemade food from trusted sources
- Questioning unusual appearances, smells, or textures
- Being cautious with unlabelled products
- Properly storing pest control products away from food preparation areas
The Queensland Health official statement provides updated guidance as the investigation progresses.

What Happens Next
Investigators face a challenging task tracing contamination in homemade products lacking commercial distribution channels. Success depends on piecing together purchase locations, preparation methods, and potential contamination points.
The Logan community remains on alert while authorities work to prevent additional cases. Health services continue monitoring hospital presentations and coordinating with pathology laboratories statewide.
For now, one message stands clear: if you have these homemade products, dispose of them immediately. The consequences of rat poisoning from homemade chilli paste and related items are too severe to ignore.
