Summary
Paraquat is a powerful herbicide used on Australian farms. Swallowing even a small amount can be fatal, and there is ongoing concern about long-term exposure and Parkinson’s disease. This guide is for families affected by paraquat poisoning who want to know whether treatment was right, and for people with Parkinson’s who worked with paraquat. It explains the risks, what should happen in hospital, the 2026 regulatory decision, and the legal questions.
Quick answer · updated November 2026
Paraquat poisoning is a medical emergency: early contact with the Poisons Information Centre (13 11 26) and a toxicology service matters. If treatment was delayed or poisoning wasn’t recognised, you can ask questions. For Parkinson’s, the regulator kept paraquat registered with new restrictions in 2026, while Parkinson’s groups say evidence links exposure to higher risk. Both situations are worth having looked at.

My brother worked on a property out past Moree. The weedkiller was kept in an old soft-drink bottle in the shed because the drum was too heavy to lift.
One hot afternoon he took a swig, thinking it was water. He spat most of it out and felt fine, and he kept working.
By evening his mouth was burning. The small hospital gave him something for the pain and said to come back if he got worse.
Nobody asked exactly what was in the bottle.

If you or someone you love was harmed by paraquat, I want you to know that your questions are reasonable, whether they are about what happened in hospital, how the chemical was stored, or a Parkinson’s diagnosis after years of spraying. These are hard situations, and every one of them deserves a proper look.
This guide covers paraquat’s dangers, what should happen after exposure, the Parkinson’s debate, what records matter, and how the law looks at it.
Why I can write this
I have been a medical negligence lawyer since 2014 and have worked on many hundreds of claims, including many involving medicines, chemicals and devices. My doctorate looked at patterns of failure in medical negligence. I am not medically qualified. The clinical facts in this article are checked against named sources, listed in the references, and I explain how I work in our editorial standards.
Start with your question
- What is paraquat?
- What should happen after paraquat is swallowed?
- How is paraquat poisoning treated?
- Does paraquat cause Parkinson’s?
- Is paraquat banned in Australia?
- Who could be responsible?
- Could this be negligence?
What paraquat is
Paraquat is a fast-acting herbicide. The Medical Journal of Australia describes it as a potentially highly lethal cause of poisoning: swallowing more than about 20 mg per kilogram typically causes kidney injury and progressive lung scarring, with death in one to three weeks.1
Definition
Pulmonary fibrosis means scarring of the lungs that makes breathing progressively harder.
In plain terms: the lung damage paraquat causes, which can develop over days.
After exposure
Anyone who may have swallowed paraquat needs urgent medical help, even if they feel well at first. The Poisons Information Centre on 13 11 26 gives advice 24 hours a day.2 The MJA authors stress the value of early involvement of a specialist toxicology service.1
Call 13 11 26 now
- A mouthful, even if spat out
- Skin splashes with burning
- Unlabelled containers involved
In plain terms: get advice immediately, even without symptoms.
Call 000
- Burning mouth or throat
- Vomiting
- Breathlessness
- Passing little urine
In plain terms: go to emergency and say “paraquat”.
In hospital
Hospitals can diagnose paraquat exposure quickly with a urine test, and blood levels help predict severity. Treatment evidence is limited, which is exactly why early advice from toxicologists matters.1 A missed history, such as not asking what was in the bottle, or a delay in contacting the Poisons Information Centre, can cost precious time.
Questions to ask
- Has the Poisons Information Centre or a toxicologist been contacted?
- Has a urine or blood paraquat test been done?
- What is the plan for kidneys and lungs?
- Should he be transferred to a larger hospital?
Paraquat and Parkinson’s
Fight Parkinson’s says a substantial body of evidence links paraquat exposure to an increased risk of Parkinson’s, while noting there is no definitive proof that paraquat causes Parkinson’s in any individual.3 If you worked with paraquat for years and have Parkinson’s, it is worth recording how, when and how much you were exposed.
The 2026 decision
In 2026, the Australian Pesticides and Veterinary Medicines Authority kept paraquat registered with new restrictions, including an 80% cut in the maximum application rate, a ban on backpack sprayers, enclosed mixing and loading, and stronger protective equipment requirements.3
Who could be responsible
Depending on what happened, questions may involve hospital care, an employer’s storage and safety practices, or the manufacturer. Workplace exposure may also involve workers’ compensation. Our medication, drug and device harm page explains product claims, and our guide to complaint or claim explains the options.
He went back the next morning, struggling to breathe. A doctor finally asked about the bottle, and the urine test was positive within minutes. He was flown to Sydney.
He survived, but with scarred lungs and kidneys that never fully recovered.
When I read the notes from that first night, there was one line: “burning mouth after drinking ?chemical. Analgesia. D/C.” Nobody had rung the Poisons line.
Mum read it at her kitchen table. “One phone call,” she said. I want to know why it wasn’t made.

What to look for in the records
Your records are often where the story becomes clear. You have a right to access your own health information. In NSW the Health Records and Information Privacy Act 2002 covers both public and private providers, and the Information and Privacy Commission explains how to ask.4 Our step-by-step guide to getting your medical records in Australia walks you through it.
| Record | Why it matters |
|---|---|
| Emergency notes | Show what history was taken and what was done. |
| Poisons Information Centre call log | Shows whether and when advice was sought. |
| Pathology | Urine and blood paraquat tests and kidney function. |
| Transfer records | Show how quickly specialist care was arranged. |
| Work records | Storage, labelling and spraying records. |
| Neurology records | For Parkinson’s, the diagnosis and history of exposure. |
| Your own diary, photos and messages | Notes made at the time are evidence too. Keep them. |
How the law looks at it
A paraquat injury raises different legal questions depending on how it happened. For poisoning, the questions are usually about whether it was recognised and treated promptly. For long-term exposure, the questions are about safety at work and the product itself, and they are complex.
A claim usually turns on three questions: whether the care fell below what peers would widely accept as competent practice (section 5O of the Civil Liability Act 2002 (NSW))5, whether that shortfall probably caused harm you wouldn't otherwise have had (Tabet v Gett)6, and, where it matters, whether you were told the material risks first (Rogers v Whitaker)78. Our guide to how a medical negligence claim works explains each one in plain terms.
In a paraquat case, the questions might be: was an exposure history taken? Was the Poisons Information Centre contacted? Were appropriate tests done and transfer arranged? At work, was paraquat stored, labelled and used safely?
In plain terms, the question is whether faster recognition or safer practices would probably have avoided or reduced the harm.
Consent is rarely the central issue in poisoning; the focus is on recognition and treatment.
Who can claim, and when
The person harmed can claim. If they have died, their family may have a claim. Workplace exposure may also involve workers’ compensation. In NSW, time usually runs from when you knew, or ought to have known, enough to claim, not from the treatment itself, and courts can sometimes extend it, so an old injury may still count. See time limits in NSW or other states, and ask early.

In my practice
In poisoning files, the emergency department notes often record a vague chemical exposure and early discharge. The later notes, after the patient returns very unwell, show what should have been asked the first time. Families are often the ones who knew exactly what was in the bottle.
Both things can be true
The hospital may have saved a life once the poisoning was recognised, and still have missed it the first time. You can be grateful for the later care and still ask about the earlier hours.
The bigger picture
Paraquat is banned in many countries, and its continued use in Australia remains contested.3 You can check a practitioner on the Ahpra public register,9 and complaints about care in NSW can go to the Health Care Complaints Commission.10 Our guide to getting your medical records explains how to ask for your file.

Frequently asked questions
Is paraquat poisoning fatal?
It can be, even in small amounts. Get urgent help after any possible ingestion.
What should I do if someone swallows paraquat?
Call 000 or the Poisons Information Centre on 13 11 26 immediately.
Does paraquat cause Parkinson’s?
Parkinson’s groups say evidence links exposure to higher risk, though it can’t be proven in any one person.
Is paraquat banned in Australia?
No. In 2026 it stayed registered with tighter restrictions.
Who could be responsible for paraquat harm?
Possibly a hospital, an employer, or the manufacturer, depending on what happened.
Can I claim for paraquat poisoning?
You may well have a claim if care or safety practices fell short and that caused harm.
