Toxicology results have confirmed the cause of the recent mass poisoning of Corella birds in Newcastle. 

The tests detected the presence of barley grain and pesticides, with fenitrothion identified in the system of all the deceased birds. Fenitrothion is a pesticide commonly used in agriculture to control insect pests. 

Investigations of this nature can be challenging, particularly when the chemical involved is commonly used across a range of agricultural and pest control activities and is readily available for purchase.

The EPA reminds all pesticide users of the importance of using chemicals correctly, following label directions, and taking care to avoid impacts on non-target animals and the environment.

The EPA has been conducting a thorough investigation and will continue looking into all lines of enquiry. Anyone with information about the deaths or possible pesticide misuse is urged to contact the EPA on 131 555.

The negligent use of pesticides that harms non-target animals or plants can attract penalties of up to $500,000 for individuals and $2 million for corporations.
