A Residue Management Notice places restrictions on the use of land. The notice is issued where land has chemical residues in the soil that could result in a risk of residues in livestock grazed on that land. Contact the Department of Primary Industries and Regional Development (DPIRD) for further information.
Land is subject to a Residue Management Notice if significant levels of long lasting chemicals such as the organochlorine (OC) pesticides (e.g. DDT, dieldrin) are found. These chemicals can be found in the soil many years after original application. These chemicals have since been banned from use.
OC pesticides are the most common cause of persistent soil contamination and consequently most residue management notices relate to these residues. They are associated with land that has been used, often more than 30 years ago for horticulture crops, around buildings, structures, or power poles treated for termites. Land with an OC soil level above 0.06ppm is regarded as a risk area for grazing livestock but soil tests may give variable results and a single soil test is only an indicator of possible risk.
The land does not pose a significant risk to human health, however livestock grazing these treated areas may accumulate residues from the ingestion of soil and as a result may have residues in excess of the maximum residue limit in their fat. Fruit vegetable and grain crops grown on this land are generally considered safe to eat, as plants only poorly absorb any of the OC residues.
The use of land subject to a Residue Management Notice by livestock is restricted. The owner will be required to prepare and implement a property management plan to minimise levels of residues in livestock. The property management plan will be audited regularly by approved auditors usually as part of an industry food safety program or by officers of the Department of Primary Industries and Regional Development. Where the owner is unable to effectively manage the grazing of the land by animals to minimise residues those animals may be subject to quarantine restrictions.
