Pesticide poisoning

Pesticides can prevent, destroy, or reduce the spread of pests.

The term pesticide applies to:

• herbicides — which kill weeds
• insecticides — which kill insects
• bactericide — which kill bacteria
• fungicides — which kill fungi

Pesticides contain active ingredients that control pests.

The body functions that are changed may be similar in other species – including people and our pets.

High levels of pesticides can harm or poison humans.

Pesticide poisoning can happen when too much pesticide is:

• inhaled (breathed in)
• eaten
• absorbed through your skin

Exposure to low levels of pesticide over a long period of time can also cause poisoning.

Symptoms of pesticide poisoning can range from mild to severe. In severe cases, pesticide poisoning can be life threatening.

If you have been poisoned by pesticides, you should call the Poisons Information Centre on 13 11 26. In an emergency call triple zero (000) for an ambulance.

Symptoms occur within 2 days of exposure to a pesticide.

Symptoms can include:

• headache
• irritated skin and eyes
• sore throat or cough
• diarrhoea
• nausea and vomiting
• extreme weakness
• unconsciousness
• seizure

If poisoning has been caused by exposure to low levels of pesticide over a long period of time, it may take longer for symptoms to appear. This is called chronic poisoning. Symptoms of chronic poisoning include:

• muscle weakness and fatigue
• difficulties with concentration and memory
• generally feeling unwell

Your doctor will examine you and will ask you some questions. They may ask you:

• what pesticide you were exposed to (you may need to refer to the bottle or packet)
• how much pesticide you were exposed to
• when and how you were exposed (mouth, airways, eye or skin contact)
• what symptoms you have

They may also arrange for you to have some blood tests.

Your doctor will need to work out how harmful the pesticide is and treat you accordingly.

You may also have treatment to relieve symptoms (such as pain relief).

You can read more about first aid treatment for pesticide poisoning on healthdirect's Poisoning page.

It is important to only use pesticides when necessary, and according to the directions on the label.

Safety equipment when using pesticides

It's important to use safety equipment and wear appropriate protection when using pesticides such as:

• gloves
• safety glasses
• protective clothing
• respirator

Other safety measures

Other safety measures include:

• keeping pesticides out of reach of children
• avoid using pesticides near children, pregnant women or older people
• throwing out unwanted pesticides at your nearest hazardous waste disposal service

Children absorb more chemicals through their skin than adults.

It's a good idea to:

• familiarise yourself with basic first aid for poisoning
• save the Poisons Information Centre number — 13 11 26 — in your contacts list
